I used, abused and ruined a couple of regular HS steel bits making a few
new nailing holes. They work but you will only get a few holes each.

Sure they do.
Maybe you might get a better reply if you describe why the masonry bit
doesn't work for you.
I tried to drill a hole in the siding to mount a flag pole holder. Since the
siding is cement board, it seemed to me that a masonry bit would be a good way
to drill the hole. Therefore, I grabbed a 1/8" masonry bit, inserted it into the
chuck of my trusty drill, and commenced to try to drill the hole. Unfortunately,
even though the bit was turning and was in full contact with the siding, the
hole did not appear. Even though I pushed harder, the bit did not drill a hole
in the siding.
While masonry bits may work for every other person who uses one to drill a hole
in Hardieplank, in this particular case, even though I followed normal operating
procedure for drilling a hole, the procedure did not result in a hole. The drill
was a standard rotary drill, not a hammer drill. The masonry bit was not carbide
tipped.
Does that help?
Was this bit some big box "special deal"? Never saw a masonry bit that
didn't have a carbide insert. But even a good quality twist drill will
make a hole in hardieplank.
Are you sure the drill was rotating in the cutting direction?

Yep, it's easily done. No matter how ludicrous it sounds check the drill.

LOL....my first thought.
Give they guy a break fellas. I burnt up two bits because my tapcon masonry
was already fried and I need the job done before it rained.
>Are you sure the drill was rotating in the cutting direction?
My thoughts exactly :-/ Don't ask me how I know! BTDT

As does a diamond burr in a Dremel. Also works well for drilling
holes in ceramic tile. And the diamond drill set at HF is cheap and
good.
KC
If the drill is turning the right direction, then the bit is dull/shot.
Without being carbide tipped, they don't last long, especially if it's
used without water to keep it cool and/or run at high speed and
overheated it.
There was another guy, in another group, that asked: How do I drill a square
hole?
And he was serious.

Why not?
Yeah...I've heard of such a thing. Not readily available. In this case a
metal punch was more appropriate.
