Drill bits for phenolic/g10/micarta

They are using a 1" deep material

and trying to get production maching speeds.

In the small sizes of knife scales and blocks- just use a HSS twist drill.
 
Man, I've cut a bunch of it and I can't recommend a burr for that. Good lord.

Carbide circuit board drills work lovely, but I'm using a regular old twist drill this afternoon. Maintain a healthy chip load, I'm turning a 1/4" 1800 RPM and feeding 20 IPM. This is wet, BTW.
 
Likewise, I just make sure it's a sharp bit but I generally just use cobalt bits since I'm already using them. I use straight flute reamers now to get the final size. I do the same with micarta.
 
I just use regular bits. I always have titanium coated on hand cause they're cheap and they seem to work good. If I happen to have a carbide in then it works good too. Mind you I don't typically drill anything more than 3/16 thick...

Bingo, that's exactly how I drill my handle materials, whether it's G-10, micarta, carbon fiber, or any other resin based material. I save my cobalt bits for the steel. The cheap Ti coated Dewalt bits I have go through the G-10 and what not just fine. I clear chips fairly often to keep things smooth and to let the material cool briefly to avoid burning.
 
Yep, regular bits here. I use a brad point sometimes on G-10 (depends what set I have out), since I'm use to using it for reducing chips/cracking when drilling wood. But I find G-10/micarta is strong enough to not chip the same way... it more or less *carves* and leaves long stringy bits wrapped around the bit afterwards.

Just always use a sharp bit and you should have no issues :thumbup:
