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

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.

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

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

Tapped hole in 12L14 steel in one pass, no need to backout to clear chips! Very nice quality.

This is a taper tap. NOT plug style. Looks nice otherwise.I will try and get it to work for me but I need to get down close to the bottom of a blind hole. Hopefully I can get enough threads in there for my part to work.

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

The tap was as described and worked great. Shipping was 7 days.

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.

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.
