MSC has anything you need.Thier catalog has charts and conversion tables in it, ect...
I use it for info all the time.
If it is made (drill-wise) MSC has it.
There's a link on my web page.

When you get MSC you might consider a metric or a "number" sized drill, compare the decimal equivalent to the drill and get exactly the size you want.

Hopefully, you're a weight lifter, if you have them send you a catalogue. It must weigh 20 lb.!

You can also order from them on line www.mscdirect.com/

I've also ordered stuff from these guys with good results www.travers.com/

Mr Johnson
I am a weight lifter I have MSC catalog I know what you mean

Nathan. Glad you can handle that book!

You cannot, I guess, get a drill exactly .223" there. But... you can come very close. I go a bit oversize so thet the screw will fit in the hole a little easier.

Look on page 35 and 36 of the giant MSC book for screw machine drills. I like this type of drill because they are pretty short and stiff and you can get by using them without a center punch, most of the time. Other types of drills are in the same area of the book.

5.7mm = .224" order # 01293307

#1 = .228" order #01383017

"A" size = .2340" order #01384015

15/64" = .2344" order # 01382159

I hope one of these will work for you. On the handles screw holes, for the large 5/16" headed Corby-type bolts that I use, I use the 15/64" size, but the others would work. I use a #11 for the smaller, 1/4" head bolts. That's a slightly over-sized 3/16" drill.

Take care, Steve

P.S.. Now I need to rest, after lifting that book around!

If you have to have it exactly .223, get a larger drill, spin it backwards with a smooth sharpening stone to hone it to the exact size.
You can also get reamers made to any size.
a reamer in an undersized hole is the best bet for repeatable accuracy.
