Hi,
I use a lot of really small endmills for circuit boards and I get them from
http://stores.ebay.com/CARBIDE-PLUS?_trksid=p2047675.l2563
Great value for money and mainly Kyocera Tycom brand.

Try PreciseBits. That's their speciality. But note: such bits are FRAGILE!

Cheers

Hi Bill,

I do a lot of engraving and a few years back I used to buy quality engraving bits from France and also re-sharpen my own bits, but no more…
Although many Chinese vendors do not seen to be able to tell the difference between HSS and Carbide their engraving bits are now so cheap on ebay that my grinding machine has been retired and I now bulk buy the bits from China. I do get a few rejects (with excess run-out) but they are just discarded.

My recommendation, check out ebay for ‘carbide engraving bits’.

Hi,
last lot of stuff I got from Drillman was these:
http://www.ebay.com/itm/0-50mm-0197-2-FLUTE-MICRO-CARBIDE-ENDMILLS-Kyocera-Tycom-1600-0197-079-/151724700078?hash=item23537f31ae
They were on special at $2.65 ea so I bought 30 of them. Use them for circuit boards, Kyocera Tycom  is a good brand, just the dogs dangly bits.

Thank you all ! ! !   The only one to get back to me was PreciseBits and John was very helpful for the Brass Bits....Anteres is now making bits for CNC just like the ones we use for our Dahlgren so we will get our bits for plastics from them
