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

I got two taps and a die from Drill America on this order. The taps are good/excellent but the hex die was a weird comically tiny nonstandard size (an M8x1.0 with a bizarre tiny 11/16 hex width almost like youd expect with the micro and jewelers tiny round dies or something). The M8 tap I received had to be returned but overall it was decently ground and good quality with some niggles in form/design compared to typical US made or US branded taps. This little 4-48 tap is great, though, darn close to US hss taps I normally use. The teeth are expertly ground and clean, angles seem right, both ends are finished cleanly. Ive only put one hole 1/4 deep into some mild steel but the action felt great and the threads were beautiful. Ill be angry-sad when this tap eventually snaps, as all the tiny ones eventually do, but initial impressions are excellent.

Benchcrafted sends machine-threaded screws to attach the Retro Crisscross and Glide hardware for their renowned leg vise, rather than wood lag bolts/screws. Surprisingly for me, they actually worked quite well. This Bottom Tap has thread cutters almost to the end of the tool, allowing you to drill a hole slightly longer than the effective depth of the screw, unlike the taps available at big-box home improvement stores which have a longer distance between the full-sized cutting thread and the end of the tap. Since Im using it on Southern Yellow Pine, theres no appreciable wear on the tap while using it, and it was the right tool for this job.

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

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.

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

The tap worked well its too bad I only needed it once

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!

Great for mounting sights on guns.

Thought a new 6-32 tap would be the right way to start a new project... It snapped on the second hole. Had to revert back to the one I had which got me through the next 22 holes.
