IRWIN Bottoming Tap, #6-48NS (1221)

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.

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.

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!

The IRWIN Bottoming Tap, #6-48NS (1221) is just what the gunsmith ordered. Save yourself a bit if hassle and get the one that comes with the correct drill bit.

The tip of the tap (which will not make threads) is a bit longer for a bottoming tap but the quality of the tap is OK and it fits very well on the threaded holes of the rifle leaving a clean thread.

Worked as advertised

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.

its works great. thank you.

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.

Great quality and it works perfectly!
