A reamer is a rotary tool that is used to bore into very hard and difficult materials. Depending on the function required, they are inserted into either a drill press, impact wrench socket, turret lathe or screw machines. Zoro supplies reamer tools in a variety of shank types, including a hex nut shank reamer, a morse taper reamer, taper pin reamers, several different straight reamers and more. Most are fluted and tapered and made of high speed steel or solid carbide steel. Items also vary by size and overall length.
