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

The taps look OK. I have not yet used them. However, a set of 3 was advertised and I only got 2 in the package. It was not worth the effort to try to return them, but I feel cheated.

Nicely made taps, but not a set of 1 each of taper, plug, and bottoming taps as described. Replacement set the same so did not bother to return replacement set.

I was able to tap into a harden shaft with this. Did it very slowly and a lot of cutting fluid.

Performed as expected.

Delivery was timely, cost was righteous, quality was good.

I ordered a set of three and just got two. Thats unacceptable

They worked perfect. The price was perfect since I won’t have a use for left handed taps very often. I used them in aluminum and were sharp enough to make clean threads. I don’t think there will be any issues using them in steel.

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.

One of the taps (the bottoming tap) fell out of the box some time before it got put into the bubble-bag for shipping. If I had _really_ needed the bottom tap I would have raised an issue with the seller but the other two taps did the job for me (it was a through-hole that I ended up using in both cases). Perhaps they could make sure that all of the tap boxes are taped before shipping.... NOTE: You do NOT have to send me a replacement tap!!! This is the first time in my life that Ive needed a 4-48 tap. (for storage spots for the little flat & ball-ended tips of a dial indicator and a little electronic height gauge)

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.
