    There are three basis types of taps: flute, plug and bottoming. This is a flute tap, not a bottoming tap, the photo does not include the flute point at the end of this tap. It looks like the bottom of the tap in the photo has been cut off in the photo. This lead me to believe the description, which said this was a bottoming tap, which it is not. Unless I want to grind off the point of this flute tap, I can not use this tap.

    Worked perfect....for those that dont know use your drill press manually to thread your hole right after you drill it..once you reach how far you want unchuck the tap and back it outby hand to make sure you feel that it threaded good and comes out with ease. I bought three taps afraid they would break but using above method kept that from happening. Will probably rust away before I ever get to second one.

    Hard size to find 6-48 Needed a bottom tap to clean up some holes on a gun barrel for mounting a scope. Worked perfect!

    It did what it supposed to do on my savage 12fv. Needs to be lubricated to push excess metal pieces. 4 stars cuz of 2 days late delivery.

    Seems well made, but did not use, since appeared would have enlarged threads for Savage 12 FV scope bases too much, and ended up not even having to chase threads in order to mount Warne 7666-20MOA picatinny rail.

    A good quality tap, does the job effectively. But, the bottoming taps Im used to are completely flat at the end with the cutting edges all the way to the end, this is not. This is more like a plug tap than a bottoming tap. Still works, but be aware of that.

    This tap has the common thread pitch for shotgun sights and is very difficult to find in stores; if not impossible. I have a Remington 870 express magnum shotgun which has the front ball sight pressed in; not threaded. After removing the ball sight, I used this tap to begin threading the hole. The hole is very shallow though, so once the tap hits the bottom, I had to dremel off the tapered bottom so I could continue tapping the threads all the way down to the bottom of the hole. For the price, the one time use didnt bother me : )
