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

I expected to get a pack of three bottoming taps like the photo indicates. I had searched for bottoming taps and when I saw a photo with three bottoming taps I ordered it. Needless to say I was surprised to discover that only one of the taps is a bottoming tap. The others are a tapered tap and a plug tap. I went back to the original sales description and scanned through all the photos. In every photo where three taps are displayed side by side all the taps are flat nosed indicating that they are bottoming taps, however, in one of the photos the set is described as consisting of one bottoming tap, one tapered tap and one plug tap. Note to seller: when you display a set of items that are different from each other then display the items contained in the set and not a photo of one item repeated three times.

Only one tap is a bottom tap. The other two are standard tapered 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.

These tap are marked HSS and seem to be well made. Im threading in Bakelite so they should last awhile.

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.

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

Worked Great , Good Products ,Great quick delivery as needed as soon as possible to straighten out a Club Car President with Frt. End Lift issue.

I needed a reverse tap to adapt a weed cutter to work with fixed blade modification that replaces the string assembly. The kit used a 3/8 reverse bolt to attached the blades. Once I received the tap, I was able to cut threads required by the bolt. Worked out well. Have used the weed cutter several times and the bolt has not come loose.

The tap set (I ordered #8-32 3-piece set) arrived promptly. It was nicely packaged and appeared to be of good quality. The cutting surfaces were sharp, and the taps nicely finished. I used them to tap several blind holes in brass, and they worked just fine. Other reviewers have complained that they are flimsy and not durable, but I certainly didnt observe that. They seem just like any other tap I have used in the past. Id definitely recommend them.

Got a set of two tapers and a plug. Complained and got another set as replacement. Same thing. If you really need a bottoming tap I guess you need to order it separate. Quality was not bad.
