Hint, hint ......

answer to an earlier post with a recommendation:
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. Larger the # smaller the drill bit diameter.

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.

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.
