Step Reamers for Precision Hole Sizing & Finishing in Metal

The Step Reamers collection features Champion Cutting Tool’s XSR series step reamers, engineered for precise hole sizing, deburring, and finishing in metal applications. Unlike step drills designed to create holes, step reamers are used after drilling to bring holes to accurate size while improving roundness and surface finish.

This collection includes individual XSR step reamers as well as the XSR-SET, providing multiple step diameters in one tool or kit. Each reamer features carefully ground steps that allow technicians to incrementally size holes without chatter, grabbing, or over-cutting.

Step reamers are commonly used in fabrication, maintenance, electrical, and mechanical work where bolt holes, conduit holes, or fastener openings require controlled enlargement and clean edge finishing. The XSR series is ideal for steel, stainless steel, aluminum, and non-ferrous metals.
