Cool. When you drill, do you have to take special measures to keep the bit from breaking out to the side?

This is the drill bit Sharpton uses to remove pins. It does not wander off the pin.
He does not file or flatten the top of the pin first and he does not use a center punch. He puts the bit into the drill press then raises the razor pin into the bit. He does not lower the bit into the razor pin.
He takes his time and checks frequently.

Thanks so much Bruno.

Coming from a professional such as yourself, that means a lot to me.

If I had it to do over I think that I would have chosen a different scale material.
What I used was black and blue jean micarta. It's not letting me get a top notch final finish that I'm really happy with.
I am really happy with the 1095 blade and the fit and feel of the knife.

I believe the # size of that drill to be wrong. A #9 is about 0.196 diameter and bigger than 3/16ths.
Here is a chart to find the correct diameters of drill bits for your purpose.

I would guess the correct diameters to be #51 or #52 about 1/16th" and a bit larger.

Split points are a great improvement over regular bits for our works.

A screw machine length drill bit has shorter flutes and is less apt to bend while drilling.

PS, Listed supplier id a good svender.

Thanks Richard

What happened is that Sharpton told us the type of drill bit and mentioned the "jobber" length. So i did a google
search and saved the link with no thought of looking at the size.

Thanks Randy for all the pics. You must have been running around clicking at everything. Its great to see all the guys and projects.

I bought the bits the Richard pointed out. I love them. They work very well for drilling out pins. The right bit and going slow makes it so much easier to drill out. But i still lower the bit to the scales. Not nearly as good as Tom being able to bring the pin the the bit.

Oops ... my second oversight ....

"Set the speed of the drill press as low as possible" is one other requirement that Sharpton has for drilling out the razors pins.

Thanks for mentioning this.

I hope that someone who has actually used these bits posts the info into the "workshop" forum.

Hint, hint ......

I had to use Charlie's a bit faster than I was used to.
Seems the back top pulley was half-there!
