Tap & Drill Chart For Gunsmiths

[Dixie Gunsmithing]

All,

Below is a tap and drill chart by Hanson, that includes most gunsmithing screws, along with the proper drill sizes, though some may fudge these. Anyhow, the 6-48, etc., is here.

Attention, Update: The photo was edited to correct the 1/64th size at the top. If you have the old one, and want the updated one, use this new version.

Thanks, can always use a tap and drill chart.
Especially for the smaller sizes.

You're welcome.

I forgot to add, that the diameter/type column is the drill diameter. Why they didn't call it that is beyond me. It is in either number, letter, fraction, or millimeters.

The poster sized drill and tap charts from Starrett sell for $10 on Ebay, but I got a few just by contacting Starrett.

Today's problem was the wife had stripped out the 6-32 screw in the GFI outlet in her bathroom.

Can't do nuthun' without a drill and tap chart.

Groovy

Thanks, I already printed several copies to post on numerous tool boxes and such.

at the top of the list there is a typo. 1/64 should be .0156 and not .0516

I appreciate this contribution to the forum. I have been using a similar chart, for years. Your is better than the one I have been using. ....

Thanks again and;

steveno,

You are correct. The 1/64th size needs to be changed to .0156" when printed out.

 

[steveno]

if you expect to do any machining beyond drilling and tapping a couple of holes I would suggest that you get a copy of Machinery's Handbook. yes it is kind of expensive but there is a LOT of information in it.

I updated the photo and corrected the 1/64th dimension at the top. How Hanson never caught this, I don't know.
