Metric: Most common: 3, 4, 5, 6, 8 mm?
I have Huot bulk drill case, in a small shop. The oddball sizes I figger a
cupla drills would be enough, but for things like #7, 21, 1/4", etc, I
should have at least 10 on hand.
Probably drill point angle would be an issue as well. Get 118 and 135 deg?
If I just went with one angle, what would be better?
In general, is cobalt worth the extra $? Coated?
I proly break shit before I wear it out..... :(

We just buy HSS drills.. 118 angle.. Unless your in a production
environment I can't see spending the extra money on cobalt/coated
drills. Drills over I'd say 3/8" we resharpen, anything smaller we just
toss and buy more. We're MSC whores so when we need something, we get it
the next day.. MSC and enco usually has deals on cutting tools so if we
know we're running low we'll wait till the coupon comes in and stock
up.. Normally buy 10 drills at a time of any particular size.

Re:metric
Get the most common clearance and tap sizes for those. And you'd be
surprised at how much you use those off sizes in the regular 115 piece
sets. I'm always needing a drill just a bit bigger for drilling out
busted screws and the like. If I could get a metric set for a decent
price by tenths(and refills!), I could probably chuck all the
fractional/letter/number stuff. It's always been a mystery, with 90+%
of the world on the metric system, how we end up being screwed on
metric tooling costs.
As far as cobalt, I've found these useful for the harder steels, like
on guns. For aluminum, probably no advantage. They're brittle, so if
you do a lot of free-hand drilling, prepare to buy spares. There is
no one drill type and material that's going to do it all.
Stan
I've never regretted purchasing my 115 piece set, and have had the need to
use quite a few of the oddball sizes when a hole had to be "just so".
I still rely on my 13 piece set for most holes though, only cracking open
the big one when I need to.

Isn't Shars just another importer? My Shars (has Shars etched on them)
vises came in Chinese crates even though they shipped to me from your neck
of the woods.
P.S. I am very happy with my large (6" opening) Shar's vises by the way. I
did have to do some minor improvements on the cross bar assembly, but at the
price I can't complain. The machined bodies of the vises are superior in
accuracy to anything I need at this time. I'm considering buying 3 of their
small 1" step jaw vises for small stuff, for the machine I intend to
dedicate to drag engraving, and for use as a lower profile two piece vise.
To the OP. I have a couple of the 115 sets. I like being able to pick up
the decimal drill bit chart and then pick out a bit within a few thousandths
of of what I want every time. I've have/had a Tin, Cobalt, and HSS sets.
The cobalt coated do seem to last longer initially, but after they get a bit
worn they are all pretty much the same. I also find that I mostly use the
same bits over and over again, so for certain things I'll probably bulk
purchase bits in specific sizes in the future. In my contracting business I
already by 3/8 bits by the half dozen. D & F also get used a lot for
setting alignment pins in molds. Also, 21 & 7 for clamping screws.
The big thing is organization. A 115 pc set is wonderful until you push it
off the work bench once. The bigger sizes are no big deal, but all those
smaller number sizes are impossible to sort again. I get a new cabinet (new
to me) and decided to put my newest 115 piece set in a drawer and never take
it out so that couldn't happen. Didn't really realize that it didn't have
proper drawer slides so of course the first time I left the drawer out while
I turned to check one of my size tables it fell on my foot. Not only did my
toe hurt for three days, but now I have a drawer full of loose bits I
scooped off the floor. LOL.
Anyway, my thought on buying specific sizes you use a lot is develop a good
system for keep new unused bits, good used bits, and worn bits straight by
usage and size.

I also have that 6" Shars vise and I am not at all complaining -- it
does its job for me.
I am thinking about buying a second one.

I like cobalt bits for drilling stuff like steel pipe. However, with small
diameter bits, it seems more likely you'll just break them before they
wear out.

I have a budget Enco set of HSS - nothing fancy. When I wear out or
break one, then it's time to consider getting a better drill bit (or
bits) in that size. As such, the sizes I haven't used are not costing me
much, but I have something in all sizes. If not budget constrained, or
less hobby and more production, different economics may apply.

TiN is coated. Cobalt is cobalt through and through - if sharpened
properly, good as new. If you just run them dull and toss, different
economics again.

Easy as reading a micrometer. Something you can set the apprentice or
kid on if you have one or the other and a slow period. Or do yourself,
unless you bring in so much money that it's worthwhile to just buy a new
set rather than take the time. Most places there's somebody who can be
useful at least part of their time doing background tasks like sorting
drill bits.

Cats, coffee, chocolate...vices to live by
I don't think they're a waste of money.
First, you get a nice drill index. Second, you get a complete set of
bits, so there's always the size you need.
Sure, the bits are junk, but that's ok. Some of them you hardly use at
all, so they won't get dull very quickly. It's just nice to have them
in case you need them.
Those that *do* wear out, you just replace with a nice cobalt bit and
drop it in the same spot in the box the dull one was in.
So you always have a complete set of bits, and the ones you use most
often are high quality. It's worked for me for years.
Or, you could spend a couple hundred bucks and get a complete set of
cobalt bits, most of which you hardly use.

It depends on your usual material and what you are using to
drive the drill, i.e. loosey-goosey drill press, Bridgeport,
lathe, etc. In general the sharper points work better with
softer material and the blunter points [135 degree] work
better for hard material. The 118 degree is a general
point. A 135 degree w/ or w/o split point will tend to walk
less than a 118 degree point. Unless you have a need to
drill the deeper holes, the jobber length drills flex more.
Without anymore information on what you are doing I suggest
135 degree screw machine length drills.

Cobalt, while it increases the heat/wear resistance also
makes a drill more brittle and prone to breakage/chipping.
Unless you are in high volume production with rigid
equipment, good quality HSS drills will most likely be more
satisfactory and economical. TiN coating can be helpful in
reducing chip welding.
One dodge that I have found helpful is to notice which
taps/drills I use the most frequently, and buy both taper
and bottoming taps, and possibly a gun tap, with 135 degree
split point drills for a tap drill, and both tight and lose
body clearence. I like to keep the taps and drills in a
plastic reloader box as this keeps everthing together and
protects the tools.

Buy a couple cheap assed sets and fill the hout up with them...
After that ( since IIRC you basically have a dedicated product line) I
would suggest buy any sizes that you routinely use in production on an
as-needed basis by purchasing at full package quantity and in the particular
style that the job dictates.
For instance, while my own kit has copius amounts of spare stub length
drills in certain sizes, which are often used for pre-reaming dowel pin
holes, ( eliminates the need for center-drilling ) as well as for clearance
and tap drill sizes for the 1/4-20 and 10-32...( and usually they brights
because I mostly machine aluminum ) it also has quite a few empty
spaces--spaces which I see no need to suddenly rush out and buy replacements
because they are basically oddballs sizes antways.
Cart is currently empty.

They are not accurately sized or ground on center.
All of the cheaper sets tend to drill oversize because of off-center tips,
or gall because the metal was not properly tempered, or do so because the
rake angles are mis-ground.

A digital caliper is close enough to determine what goes where.
Measure across the flutes at the tip, because the shank is often a
little smaller than the tip. And at least the Huot indexes mark the
decimal diameter by each hole -- even decimal inches on the metric sets.
(Yes, I keep a pair of metric sets -- 1.0-6.0 mm and 6.1 to 12.0 mm to
both give the right size for metric hardware, and to fill in gaps in
sizes between the letter, number and fractional sets.

Ouch!
But it is worth your time (you are a hobbist, are you not) to
sort them properly back into the index. If a commercial machinist, your
time is money, and you may be better off getting a new set to save you
time finding the right bits from that drawer. :-)

Well, yes. Mostly. LOL. People have started finding me though. Its

You didn't say what you paid for the set, but if you do any (read that as
_ANY_) press fits or shrink fits, you'd notice in a big hurry.
LLoyd
Yes, I said: "bought the Enco $100 118 degree set a couple of years ago"
You may be correct about a press fit. I was taught to drill undersize &

MikeB
> You may be correct about a press fit. I was taught to drill undersize &

You certainly can't drill directly on large diameters (say, over .25"),
but you can with smaller bits and a good, low TIR chuck -- IF the bits
are well-sized and properly ground.
I've had multiple sets of both the inexpensive "made in USA" and Chinese
115 bit sets, and ultimately they always dissapoint. FWIW, the usual
flaw the the low-cost USA brands is mis-grinding, not Chinalloy hardening
or tempering, or under-sized/oversized drill stock. Hell, I've had
offshore sets where adjacent sizes in the index were exactly the same
size! (AND mis-ground!)
I even followed the (good) advice of "buy cheap, then replace the ones
you use with good bits", but inevitably ended up screwing up some
expensive work with the _next_ cheap bit I used. So I eventually broke
down and sprung for a _really_good_ set, and haven't looked back. (and
yeah... I still bugger one up now and then, but I buy the replacements
from the same source). Just one messed-up part 60% into the job is
justification for the price.

My own preference is for the 135 degree angle, which usually
includes a split point -- does not walk on starting on a slight angle,
unlike the chisel points with the 118 degree points. I even was able to
drill a cross hole in a 5/16" round shaft (for a roller for the garage
door tracks) to install a cotter pin using a hand held electric drill
motor with it still in the garage door. No way I would have been able
to do that without a spotting drill first with the 118 degree chisel
points.
The split point also means that you need a lot less force to
drill reasonably than with a chisel point.
I've seen one with one of the two flutes ground with a negative
clearance angle on the tip. :-)
And the index that these come is is a real pain to use compared
to a real HUOT index.

Mea culpa, DoN.
See also my corrected reply to PrecisionmachinisT
As for Chinalloy -- I had a set perhaps around 1962 or so of
bits from Japan before good tools started coming from there. Butter
steel. Terrible -- a set of 1/16" to 1/4" in a little index with a clear
plastic front panel in the index.
> Hell, I've had

The 115 piece bit set which I got, while marked "Made in USA" on
the flyer, was over $200.00 perhaps ten years ago or more, and was (and
still is) a very good set (from MSC, FWIW).
Had I known then what I know now, I would have paid extra for
the 135 degree split point set. I've got a set of semi "Silver &
Deming" fractional bits with split points -- and no shank larger than
3/8" even with the largest bit size being 1/2". Index is painted bright
yellow, and I picked them up at a yard sale. Not cheap, but good
quality steel and well sharpened. (No, I would not have paid that for a
similar set of 118 degree points. :-)
I've also got a set of cobalt steel number (wire sized) bits in
screw machine length with the 135 degree split points. I'm quite
pleased with these.

I tried that with a cheap set of metric bits -- and quickly gave
them away after looking at the grind -- and experiencing the index,
which was terrible. :-)

Mine *knows* that any project involves purchasing tools. She

I am under the car or whatever. She's even gotten to the point where
she anticipates the next tool some of the time. :-)

> But don't reamers cost a fortune?
They aren't free, new. But I picked up nearly a shoebox full of assorted
decimal sizes - all in hot-dip - from .25" through just under 3/4" from a
garage sale for $25. You'll see decent ones around occasionally.
Still, a straight-flute chucking reamer in .785" (which happens to be the
common size for one of the tools I make a lot of ) only costs about $30,
and lasts for many, many holes if it's treated properly.

I'd also like to know. Doesn't a center-punch (or center drill, on a
mill) help with that? Have you found drill bits to walk in an ordinary
drill press?
I'd have thought that the 135 degree bit would be applicable for a more
aggressive cut than a 115, or maybe it simply has to do with what you
want the bottom of the hole to look like, but I simply don't know.

Yes -- those actually work. But the catalog numbers and the
main catalog URL were sufficient. And easy enough to go from one to the
next with the "find it" near top center of each page.
Interesting that they only list 0.5 mm size steps for the metric
drill bits. I've got two HUOT metric drill indexes with 0.1 mm steps.
I guess that Huot makes the dispensers in 0.1mm size steps too.
I like the #1 - #80 dispenser (the most expensive one listed
there.)
Thanks,
===========
Much depends on the type of work you are doing.
"Complete" sets are indeed expensive, but normally you only
need a few sizes. It can be useful to get three reamers,
one undersize, one on size and one over size in your common
sizes. Most any good mill supply should have in stock, but
for illustration see
http://tool.wttool.com/search?p=KK&srid=S9-4&lbc=wttool&ts=custom&pw=reamer%20straight%20flute&uid=21976513&isort=score&view=grid&w=Chucking%20Reamer&rk=2
http://www.wttool.com/index/page/product/product_id/34395/product_name/7-Piece+Chucking+Reamer+Set+%28WT%29
Depending on your shop practices/equipment, a useful reamer
modification is the trimming the reamer length to about the
same length as a jobber or even s/m length drill in the same
size as this will allow you to drill and ream a hole in the
same set-up with out losing alignment cranking the table
down or head up for clearance, moving the table to change
tools, etc.
Unless you have a heat problem, the invention of loc-tite
eliminated much of the need for press fits and very tight
hole tolerances.
If you have the time you can also make your own reamers, and
these are easy to sharpen. see

One bonus of the drawers is that after I retrieve a bit, I can take

Penn Tool is a little cheaper for that part:

That is a nice one. I have it's little brother (#1 - #60) and the
fractional dispenser. Both are real time savers.

How do you define a non-integer count of drawers? By weight
compared to some standard drawer?
There is such a thing as excess precision. I knew a machinist
who did woodwork to 0.001" -- even knowing that it was going to change
when the next cloud blew by. :-)
He was doing it for himself, so he was free to do so -- but
doing it for someone else, and *charging* for the extra time and care
needed to reach that level of precision is another thing. Of course, if
the drawings *called* for that level of precision, everything would be
rejected by outgoing inspection anyway, unless the whole shop and
inspection area were climate controlled. :-)

O.K. When I go to the bins of bit envelopes, that bit is going
into an index to replace the too-dull one as soon as its immediate job
is done.

O.K.
Yes -- quite a bit cheaper. And I see that *they*, at least,
list the smaller metric in steps of 0.1 mm -- though to cover the full
range that I have we still have problems -- because the 7.0 to 13.0 (in
the 1 mm to 13 mm case) is in steps of 0.5 mm. Hmm not using the 1.0 to
7.0, which give 13 extra spaces in that one, but I need 51 spaces for
the 7.0 to 12.0 which I actually have in an index -- and need to
re-label the drawers. Two of the 1 to 13 drawers should do it. The
question is whether the smaller end of the metric drawers would hold 7.0
mm or larger bits?

BTW Have you noticed the little hook on the left side of the
partition between the letter and number sizes in the 115 bit
HUOT indexes? Ever wondered what it is for? It turns out to be
just right to hold the HUOT #61-80 index, which I already had,
so I have a 125 bit index instead of 115 bit. :-)
I wonder which of the wire size ranges is covered by the
"Fractional, Wire & letter Dispensers"
And I wonder which of the drawer sets has been relabeled to make
the #1 to #80 (84 compartments) set. Since the price is the same as the
"Metric 1mm to 6.9 mm by 0.1 mm" set, and I suspect that they go by the
amount of metal used, they may be the same but for labeling. But the
metric set would use only 59 slots, not 84.
Enjoy,
Either that or by determining what fraction of an additional bit
a given drawer could accommodate in relation to the average
drawer of the same size range. I will stop here because I do
not want the headache. :)

BTW, today I saw Joe the Real Machinist turn an aluminum part down to plus
or minus half a thou or less. I was sitting here in my office, and he came
to my door, and said, "Hey, Rich, my dial caliper said I still have seven
thou to go, so I miked it and it's within a thou, but I think I can kiss
it down to dead nuts. My dial caliper is off by seven thou!" I said,
"Well, it's a good thing you stopped to check!"
I think he got it dead nuts, at least at room temperature. I think it's a
pride thing. :-)
Oh, just remembered - for lube he was using something that looks
and feels very much like 80 weight gear oil. And he had a brand-new
carbide insert in his bit holder in his tool holder.
Cheers!

In addition to showing the next larger fractional, letter/number and
metric size drill bits corresponding to a decimal value input, plus the
next two larger and smaller drills - and the clearance, it now also
displays target RPM for a particular drill size,
It defaults to 60 SFPM (a good start for mild steel) and you can tweak
the value depending on the material being cut or drilled.

Winston Churchill once came to Virginia after WWII to attend the
unveiling of a bust honoring him at a local university. At the reception
afterwards this well-endowed southern belle pushed her way through the
crowd and came up to Churchill, where she told him that she had driven
all night over 200 miles to see the unveiling of his bust. Churchill
looked down at her chest and then up into her eyes and said "Madam, I
would have done the same for you!" No wonder why we love this guy.
Silly me! When you said, "well-endowed," I thought you meant smart! ;-)
I once saw a t-shirt on a large-breasted woman that said, "I wish

Cool! I'm looking forward to it.
So far, I have an error running under wine (Ubuntu Linux)
Apparently it needs a helper program, because it alerted:
"import_dll Library MFC42.DLL".
*Further 'Feature Creep' Request:*
It'd be cool to have a dialog box revealing the 'cone depth'
for a given drill ground to a given angle.
For example:
A 0.25" diameter drill ground to 118 degrees included angle
will leave a full diameter through hole in a workpiece if
the point of the drill travels at least 0.0751" past the
bottom edge of a given workpiece. Less, and the hole
will have a conical cross section at the bottom.
This feature would be excellent for determining the thickness
of a sacrificial backing plate on a mill or drill press, for
instance.
--Winston
You can download today's update (same URL) and see if the features you
requested do what you want... It defaults to a 118 degree drill point.
If you're using a different drill angle, change that first before
entering the decimal size, or enter the decimal size, tab to the drill
angle and then tab out of that to get it to recalculate cone depth.

That (mfc42.dll) is a standard MS Windows file. The only hassle you
might have is finding a version that works with both Wine and
Fractions. For some more info (because I can see you're uneasy) see:
http://wiki.winehq.org/FAQ#head-2697b3c2437625eb387ae7360d9b224be0d20bce
I've downloaded numerous dll's from that site in years past when I was
still running WinNT4. No problems, other than finding the version I
needed...
Thanks again Leon!

Carla's utility is growing to encompass the information
that machinists need in one place. It'll answer the most
critical questions we have about RPM and depth clearance
as well as the proper drill for a given tap size.
Think of it as a Grand Unified Wall Chart. :)

With a full load of bits, I would expect it to crumple in the
middle if you picked it up by the ends. :-)

Where were you Micing the bits? They normally taper a little
being made widest at the tip -- so they don't drag on the sides as much
in a deep hole. If you mike at the shank, there is no certainty how
much smaller they will be -- but they are unlikely to be larger at the
shank, unless they are really weirdly constructed.
