Drill America 3/8-16 UNC High Speed Steel Tap Set

Arrived in good time, and used in Aluminum material tapped gave a great thread.

I spent over 10 years in a machine shop and can say these are legit taps. Not the cheap carbon ones...these are HSS and ground well. True gun tap, bottom tap and plug taps.

Was just tapping aluminum, but did a great job. Had some mounting bolt threads that stripped on a Kohler engine. I drilled them deeper, and tapped with this set. The bottoming tap gave me a few more threads to screw in to.

good quality for the price, they work well.

These are great 2-56 taps. Im using them in aluminum. A little tap magic and going slow is all you need.

These taps DO NOT have the center for using a tap follower as pictured.

Used it the first second I got a chance with proper cutting fluid. Extra careful 1/4 turn and back out a little to break the chips. Broke off inside of the hole.
