Drill America - DWT54506 5/16-18 UNC High Speed Steel Bottoming Tap, (Pack of 1)

Great for mounting sights on guns.

This 6-40 tap cleans the Ruger front sight hole on the Mark III & IV 22/45 Lite.

Used this tap to remove some metal that had ponded in the threads of a nut that I had welded to something. The tap removed the metal cleanly and accurately, no discernable difference in fit between the repaired nut and a new one. For the average Joe this will likely work fine. Just remember to use a cutting oil to prolong the life of the cutting edges!

It works. But it’s too small for my application

Cut threads very well into extruded aluminum

Bought this tap to thread holes in a cast iron transmission pan on an old tractor. It cut the iron no problem. Did 8 holes and was still cutting the threads well. Very happy. I used a size F drill bit and then tapped the holes with this. Nice tool.

I used this to clean up the threads on a Model A Ford Zenith carburetor jets.

I bought these having to do a project. Tap works great!

Worked like charm saved my but on valve cover head did what supposed to do. Stripped and crossed threaded bolts suck glad u guys had right size great quality held up still looks good glad to add to my tap set will get more taps from u guys in future

I use a cheap one to chase stuff etc but this was hi quality to me anyway
