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

This 3-48 tap cut cleanly and easily, small taps are always a challenge. Very nice

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

I hand tapped over 30 holes at 4mm depth for some grub screws and they all came out perfect. Lots of the negative comments are from misuse. Remember to use cutting oil and back out a little constantly. Most importantly, make sure you are pre-drilling the right size diameter hole before tapping. The correct size can be found online. For an M4 tap, you need a 3.3mm hole.

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.

As a gunsmith I deal with many abused platforms. This tap works wonders for chasing 6-40 screws like scope rings and small trigger group screw holes. Ordered and it showed up as promised.

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

worked for me

Good price. Works well.

Good quality and cuts through aluminum like butter.
