Norton 66260195018 Diamond Dresser Convex Radius

Product Description

The NORTON 66260195018 is a single-point diamond dresser designed for dressing and truing grinding wheels in precision grinding applications. It features a convex radius point geometry with a 75-degree included angle, making it suited for controlled material removal and consistent wheel profile restoration. The 0.125-inch shank diameter and 1-inch shank length fit standard dresser holders commonly found on surface, cylindrical, and tool-and-cutter grinders. This dresser is a non-resettable type, meaning once the diamond tip is worn, the tool is replaced rather than repositioned. Machinists, tool grinders, and maintenance technicians install this type of dresser as part of routine wheel conditioning to maintain cut quality and dimensional accuracy.

This diamond dresser is used in machine shops, grinding rooms, and maintenance departments where grinding wheel condition directly affects workpiece finish and tolerance. The convex radius point is appropriate for dressing standard straight wheels as well as profiled wheel faces. It fits into dresser holder setups on bench grinders, cylindrical grinders, and surface grinders that accept a 0.125-inch shank. It is not resettable, so it is treated as a consumable tool replaced when tip wear degrades dressing performance.

Compatibility

Designed as an OEM-style single-point diamond dresser for use in standard dresser holders that accept a 0.125-inch shank diameter across common bench, surface, and cylindrical grinding machines.

Installation Notes

A qualified machinist or tool room technician should install this dresser. Before mounting, power down and lock out the grinder per OSHA lockout/tagout procedures. Secure the shank fully in the dresser holder with no overhang beyond the specified shank length, and verify the holder clamp torque is appropriate for the application per the machine manufacturer's guidelines. Never use a worn or chipped diamond tip, as irregular dressing can cause wheel imbalance or surface finish defects on the workpiece.
