Worked fine

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..

Works Fine

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.

It's secretly a square drive reamer

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.
