Drill America DWT54511 5/16"-18 UNC High Speed Steel Tap Set

I have only used this set once so far, but that's all I really hoped to get out of it. I have an aluminum AeroPrecision lower that came to me with a stripped or poorly threaded takedown pin mounting hole, which takes a 4-40 setscrew.I used the bottoming tap in this set and a little oil to successfully re-tap the mounting hole. These taps are tiny and any tap handle you already have will likely be too big. You need what is called a pin vise, basically a handle with a small collet on the end, to hold these small taps.These taps saved me a whole lot of hassle, dealing with returning a serialized item for warranty work. They cut quickly and smoothly, at least in aluminum. Worth every penny, even if I never use them again. Besides, what real man has ever said "I wish I had less tools?"

Arrived quickly, and worked perfectly!

The tap set (I ordered #8-32 3-piece set) arrived promptly. It was nicely packaged and appeared to be of good quality. The cutting surfaces were sharp, and the taps nicely finished. I used them to tap several blind holes in brass, and they worked just fine. Other reviewers have complained that they are flimsy and not durable, but I certainly didn't observe that. They seem just like any other tap I have used in the past. I'd definitely recommend them.

Needed to tap my bell housing bolts normal tap wouldn't thread deep enough, this one worked better, right tool for the job.

Drill America seems to make good taps and drill bits . They hold up well

I stripped the threads out of the cast blinker on my bike. I went up a thread size but my pointed tap only put in about 2 threads (a little less actually). I couldn't find a bottom tap in town so I ordered this one. I ran the bottom tap in the blinker and was able to get a couple of more threads. Everything worked out good.

I was replacing plastic casters on metal plant Dollys. The plastic caster had a stud that screwed into the dolly about a quarter of an inch. The replacement casters had a stem that was longer. I need to extend threads in a plant dolly to get a more secure installation. Overall I purchased three of these taps. Great quality. I did use cutting oil and cleaned out the hole before and after. I cleaned the tap after each use. I have twenty of these dollys and replaced four casters on each.

These worked flawlessly

This set of taps is NOT what is shown in the photo to be a set of three taps taper-mid-bottom taps but what arrives is a single tap. Don’t be fooled by the photo and lack of item description like I was, buy elsewhere!

Parts had a coating that looked like rust, but isn't.Good tools, they work fine. Great delivery, I am happy!

Works as described

Does the job as it was intended......Would buy again as long as the price is competitive

Broke several brand-name taps when tapping into railroad spikes for a small DIY project, but those held on. Positively surprised.
