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

cant have to many 1/4x20 taps

Used for manual thread cleaning. working well even w/o lubricant

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.

Great addition for the hobbyist, starting and bottoming taps included.

Always a great product. Never had any issues. Keep em lubed.

I’m new to the hobby and broke a tap I purchased from another seller fairly quick so I thought I’d experiment with the set. I’m using a 1/16th to bore out the post and getting beautiful threads. I refer to the set as a cutter, a rough and a finish. I’m using the cutter and rough as often as I can, but some of the posts are so shallow I use the finish because the others won’t bite. I’ve got a dozen cars done already and see these taps working for easily double, triple, who knows how many more.

These are not high speed taps, so if you put them in your cordless drill to tap a number of holes, there is a good chance youre going to break at least one. I guess thats why they come in 3s.

Performed as expected.

one of the three broke immediately on light metal. not a happy camper.

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.
