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

Seems to be well made and is of great quality, performs great for what I needed.

worked for me

Cut threads very well into extruded aluminum

Very economical tap. Works fine!

I received this product and it was of great quality and completed the job perfectly. I used it to tap aluminum piping. Unfortunately after completing the job, I realized I had purchased the wrong size. Overall though, it did a great job at what I ordered it to do. Thank you!

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 tap worked for me. Had to redo a cross threaded bolt hole on my Harley. Just took it slow with plenty of oil, and after a few turns I was able to restore the threads. Just take your time.

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.

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

it literally broke on the first bolt hole I tied to clean the existing threads on.... I never have broke a tap in my life and did not put hardly any pressure on it, I do believe it was defective... I lost my money this time
