Does anyone use a drill bit for chamfering instead of a countersink? If so, which size, or do you use several different ones depending on hole size.
 
If you`re talkin about chamfering for pin holes
in the bolsters, I made mine own tool for that.
Its cuts a tapered hole.
 
Actually I was referring to chamfering decorative holes in the handles. Sorry I didn't make that clearer.
 
RA, since drill bits are made to cut more agresively than a counter sink, they chatter alot and leave an uneven bevel. I would recommend going ahead and paying the extra to buy a good counter sink bit. You can get them from Sheffields for a reasonable price as well as stores like Lowes. Although I don't recommend the Lowes ones for steel. I think you'd be alot more satisfied with the results.
 
If you do buy one, get a single flute instead of the multi-flute chamfer bits. It's much smoother with no chatter. I just picked one of these up after using a cheaper (multi-flute) chamfer bit and couldn't believe the difference. Pricey little guys but worth it after relieving several dozen holes in a drilling session.
 
I use single flute carbide countersinks. They cost more up front, but they last longer and cut clean. Avoid impacts that will chip the leading edge.
 
Yup ! single flute, good stuff and I like slow speed. Howver, I have used drill bits for the same and the results are usually as mentioned above (chattery and uneven bevels as far as metals) for handles materials not so bad at all. But get th countersink, no sense wasting time with drill bits. Good luck bro :D
