4-Step Standard Prop Reamer

Stepped Reamers are for use enlarging the hole in aircraft propellers whilst maintaining centring. Since they cut the material accurately, your propeller will run more concentrically, thus reducing vibration, a major cause of engine/radio wear! It's even possible to remove the handle and mount the cutting bit in a drill press for added precision! Taper Reamers are used primarily for cutting holes in model car body shells, but will work equally well on soft woods and thin sheet metal – the pointed tip means that you don't even need to drill a pilot hole. Drills holes from 3~14mm. Cutting bit can be safely stored in its own handle.
