Jayru 17 Report post Posted March 20, 2010 Anyone know what this is comparable to in a "standard" size? No one in the greater NE PA area seems to carry it (or even know what it is). The Global West rear leaf spring bushings say it's required to run a 1/4" x 28 size tap through. I'm stumped! Quote Share this post Link to post Share on other sites

Fordrevhead 29 Report post Posted March 20, 2010 that's a "number drill." Number drills fall between the common fractional sized drill bits below .23". Above that these same "in between sizes" are called letter drills up to .413". The closest standard fractional bit to that is .2031 (7/64") and then .2187 (7/32"). Both of these are included in standard small drill sets. Quote Share this post Link to post Share on other sites

I figured the other bits would be to small/big to use. Quote Share this post Link to post Share on other sites
