BROWNELLS - Taper Pin Reamer

Worked good. Not sure what the other reviews were talking about. I went slow and used lots of oil. It took probably 20 mins to ream one hole..

With respect to other reviewers on here, I will tell you that this reamer works fine. It is not a DRILL, IT IS A REAMER! Drill your holes from the small side of the sight if using one with the holes already drilled in it. Use a #32 drill bit. Use a clamp on one of the barrel bands to hold it where you want it. Go slowly. Then use your reamer from the large hole side. That is the ejection port side. Take your time. Only turn the reamer clockwise. Use some tap oil.

As others have noted in the reviews, the handle comes off easily by gripping the reamer shaft in some plastic soft jaws in your vise and pulling the plastic handle off by hand. Once I did this, I was greeted by a square drive taper reamer that I could put in my small tap handle and get much better control over the process. With the stock handle, this reamer is great for cleaning up a taper pin hole, but when working a freshly drilled front sight base it's best to use a bigger handle since you're going to be turning it a lot.

The force needed to ream the pin holes destroyed the plastic handle in seconds. You are left with a standard 2/0 reamer with square drive top. Using a square drive tap handle, the reamer worked perfectly to install two standard FSB taper pins. I'm not sure how many pins this reamer is good for, but it worked well for my limited use.

This is a fair price for an Asian imported #2/0 High Speed Steel, 4 flute twist tapered pin reamer. Any SMALL tap wrench handle will fit it, but the long screw handle twist handles work best for tapering straight holes. You don't want a faster twist rate, trust me! If you want made in USA, it's out there, for $45-$55, with no handle and no shipping. Made in Germany or Switzerland? $60-$90. You can chuck this up in a drill motor too, but plan on breaking one or two before you figure out exactly how that procedure works. If you already know, go for it. You probably also know you run a risk of breaking it any time you do use this technique, but it can be done. USE CUTTING OIL! It really helps a lot! THE HANDLE WILL PULL OFF or it can be chiseled off. Then use a small tap handle, as this does have a square pin/peg on the end, just like any tap does.
