Drill America DWTT1/2-13 1/2-13 Carbon Steel Taper Tap (Pack of 1), DWT Series, Uncoated (Bright)

Worked like a charm! Very satisfied with this bit

I used these to prep a new steel bicycle frame derailleur nut. Because the paint was in the threads, I could not properly screw on the derailleur. I used the more blunt one first, as I had already crossed the threads with repeated failed attempts, then I proceed to use the sharper one for a final cleanup. Very effective! Derailleur screwed right in afterwards.

good!

good!

This is a taper tap which easily advances in a prepared hole of correct size or for use in chasing damaged threads. Good value for the money.

Good price for my needs easy to use for re-tapping holes

Nice, easy and quick transaction. Tap set was perfect for reclaiming a 10-24 thread on a tool that woud have cost $50 or more to replace.

Jan2023: a performer for the price point, cuts cleanly with properly ground/dressed flute edges. Nickel-alloy content similar to more expensive taps thus easier to get started in steel.. At least the ones i received this order werent like the poorly manufactured threads you see too often.

I use this tap on a small block Chevy bell housing just to clean the threads if they get rusty or whatever just for clean up and Ill get a good bolt makes a good bolt thread for your new bolts

Worked as advertised. Easy and did a great job.
