Flutes are nicely ground and the reamer cut cleanly leaving a perfectly tapered hole in no time. I used a tap handle and manually reamed two pin holes in a couple of minutes.

Used to ream holes for taper pins for an A2 style front sight base. Worked perfectly.

Cuts cold rolled 4140 easily. Cut a hardened steel shaft on an ancient milling machine too, with some effort. Stayed sharp.

This bit worked perfectly paired with a No.31 drill bit. I have only used it a few times so I cannot comment on its longevity but for light use it worked perfectly.

Perfect for that lovely A1 in your life that you're trying to taper, never having done it before it is easy to use and makes for a great product. Don't over size your hole! Measure often and cut slow. You too can achieve your dreams
