Needed this specific size for a custom muzzle brake project and it worked flawlessly. The high-speed steel holds an edge much better than the cheap sets you find at the big box stores. The tap cut smooth threads in 4140 steel without any binding, just make sure you use plenty of cutting oil. It's a solid investment for any machinist.

The drill bit is great but the tap felt a little stiff on the first few passes. I managed to finish my project but I was worried about snapping it. Its okay for the price but maybe not the highest quality out there.

Honestly surprised by the quality here. Drill America is usually hit or miss for me but this kit is a win. Saved me a trip to the specialty tool shop and cost half as much as the individual bits usually do.

Exactly what I needed! The 5/8-28 size is hard to find locally. Five stars.

It’s a decent kit for light duty work. The 37/64" bit is sized correctly, which is the most important part, but the finish on the tap flutes was a bit rough out of the box. I spent a few minutes cleaning up some burrs before using it. It works fine for aluminum or mild steel, but idk if I’d trust it on anything harder. It's a fair middle-ground option.

Drill bit was dull right out of the package. I had to resharpen it before I could even start the pilot hole. For what they charge for these "kits," you'd expect them to actually be ready to use. Very disappointing quality control.

Way better than the generic brand I bought on a different site last month. The tolerances feel much tighter and the threads come out clean every time. No wobbling with the bit either.

Got this for a spesific job and it held up well. I was worried it might be flimsy since the price was lower than the industrial suppliers, but it did the job nicely. Pro tip: go slow and back it out often to clear the chips.
