Precision Reaming System
Proto-Cutter XR Reamers are designed for tight hole tolerances, concentric holes and superior micro finishes. One replaceable cutting blade is supported by guide pads to guide the reamer in a predrilled, bored, or cored hole. Reamers are made for through or blind hole reaming. Proto-Cutter can custom design an XR Reamer beyond our standard dimensions.
XR Xtreme Blades
Proto-Cutter XR Reamer blades are manufactured from high quality micro-grain polished carbide. Edge honing is applied to the blades for certain applications to reduce micro chipping. Blades are double ended to minimize cost. Lead and rake angles are determined by our sales engineers to maximize micro finish and concentric holes. Please consult Proto-Cutter sales engineers for lead angle geometries to suit your application. Reamer blades can be coated with TIN, TICN or TIALN. Other coatings are available depending on the material and application. Proto-Cutter also makes replacement blades for reamer bodies made by other manufacturers.
