Multi-Roller Burnishing Tools

ROLL-A-FINISH multi-roller tools deliver an efficient solution for burnishing cylindrical surfaces and bores. Designed for both internal and external applications, they improve surface finish while increasing surface hardness and fatigue strength—all in a single operation. Suitable for steel, stainless steel, aluminum, and high-strength alloys, the tools provide outstanding process reliability, consistent results, and shorter cycle times. Multi-roller technology ensures uniform surface quality with minimal tool wear, making ROLL-A-FINISH the ideal choice for demanding production environments.
