Preamer 2 pcs No.3 Straight Shank MT3 Morse Taper Reamer Set for Lathe Milling Tool

I used these reamers to create an MT3 taper in a 10" pulley I purchased to replace one that broke on an old air compressor pump. These reamers did the job beautifully milling the aluminum pulley. I expect the will work just as will for cast iron but have not verified that to be true.

P Reamer went above and beyond in the customer service area with a replacement set of reamers even when it was not their responsibility to do so. Reamers are of good quality and will serve my purpose well. Thanks Again.
