Drill bits & tap for titanium liners?

[XSanguin8]

Can someone recommend some drill bits and taps to drill and tap titanium liners to accept pocket clip screws?

I have several knives I want to convert to left hand carry and provide tip up/tip down carry options to.

It only needs to drill thru about 1/16 of an inch. Hole is about 3/16th to be tapped. Screw threads are the ones used on Emerson pocket clips.

Recommendations and tips/tricks would be appreciated. I've drilled and tapped for automotive applications before, but not for knives.

Thanks!

Screw threads are the ones used on Emerson pocket clips.

I'm assuming that since Emerson quotes inch specs on his site, he uses inch spec fasteners and not metric.

You choices are

0-80
1-72
2-56
4-40

google a chart and measure what you have and then get back to us

I'm betting on 2-56
and a drill tap chart will reveal a different #ed drill for each size


then when searching for taps, try to find a spiral flute tap.

Emersons are indeed 2-56 thread.

If I recall correctly , its been awhile since I drilled and tapped 2-56 in .050 Ti , I believe I used a 5/64 bit , but that only gives approx 65% thread , for more thread use a #50 bit.

If your using 2-56 plug tap go with a #48 drill. but i reccomend you use a thread forming tap with a #47 drill or 5/64. thread forming are far tougher and much harder to break.
