Hmm... I suspect that some or most of those cheap bits at ebay
are Chinese products.

It wouldn't make much difference for me even if they did ship to
India because import hassles are a real PITA and well nigh
insurmountable for those of us in remote parts of the country.
But things have started looking up a bit recently in that
respect. There are now at least a couple of Indian companies who
offer to import just about anything from the US for a client.
Their minimum shipping charge is for 1lb.
The prices are comparable to those at ebay and are certainly
better than at those other sources. At least the manufacturer's
name is known. Do you know anything about the other brand
mentioned there - Precision Carbide? Unless someone comes along
with a more attractive suggestion - not necessarily a lower
price - I think I'll make a trial order for a ten-pack each of 2
or 3 different sizes.
Another thing I'll have to deal with is the drill. The 10k rpm
drill I now use came only with 0.8mm, 1mm and 2.3mm collets.
Thanks for the helpful input.
