About to send some of my cutters in to get sharpened and was wondering if any of you guys have used a diamond hone or something similar to touch up the cutting edge on BB taps. I've heard of this as an elbow grease machinist method. A couple of machinists I know also recommended a Dremel with a grinding bit that matches the rake, but I think I'm too clumsy to risk that on a $160 tap
. I have a good set of kitchen knives that I'm able to keep nice and sharp with the occasional honing, was wondering if this logic also applied to taps
. The facing mills and reamers I'll leave to a tool grinder, I think sharpening those is more tricky.
