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

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

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.

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

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)

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 used grade 8 bolts into schedule 40 pipe after drilling and tapping. The tap started and cleaned easy.

Machining brass these work great. These taps do not list the H value for pitch size, example H1 is .0005 inch over nominal pitch diameter each value add .0005 inch. Most taps are made at a H2 or H3 value. These seem to be H3 work very nice and you cant beat the price. These are 4 flute, hand taps, tapping block is recommended, get any tap sideways and good bye tap. The shank diameter is above the minor diameter so thru tapping past the end of thread is not possible, you would need a special taps for that, this is not it. Nice tap set great for hobby work, professionals dont guess at pitch sizes.

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

Just one tap. Expected 3 as shown in picture.

All three styles of taps are included in this purchase.
