Size: 3System of Measurement: Taper Pin Verified Purchase
I use this for reaming holes for taper pins to lock cutting jigs in place. The left hand spiral pushes the waste material toward the end of the reamer, and keeps it stable while drilling. It works surprisingly well with a hand held drill, shaving off a little material at a time until the pin is the desired depth. Note that these taper pins all have the same taper angle, but come in different sizes (length and min/max diameter.) One size of reamer may cover more than one size pin depending on how deep you go with the reamer and how long the pin is.
