Norton 66260157007 Diamond Dresser 1/4 Carat

Product Description

The NORTON 66260157007 is a single-point diamond dresser used to true and dress abrasive grinding wheels in machine shop and industrial grinding applications. The tool features a 1/4-carat diamond tip mounted to a 3/8-inch diameter shank that is 2 inches in length, allowing it to seat securely in standard tool holders and dressing fixtures. Single-point dressers restore wheel geometry, remove glazing, and open the wheel face to maintain consistent stock removal rates. This dresser is non-resettable, meaning the diamond is permanently set and the tool is replaced rather than reconditioned when the tip wears.

Single-point diamond dressers are used in precision grinding operations across tool and die, metalworking, and industrial maintenance environments. They mount in surface grinder dressing attachments, bench grinder tool posts, and cylindrical grinder dressing units. The 3/8-inch shank is a common size compatible with a wide range of dressing fixture holders found in production and job shop settings. Typical users include machinists, grinding machine operators, and maintenance technicians performing wheel conditioning between grinding cycles.

Compatibility

Installation Notes

Installation is performed by machinists or grinding machine operators familiar with wheel dressing procedures. The dresser shank should be clamped securely in the dressing fixture with no more than the minimum necessary overhang to reduce vibration. The grinding machine spindle must be running at operating speed before the dresser contacts the wheel face, and the machine must be fully powered down before mounting or removing the dresser tool. Always wear appropriate eye protection during dressing operations, as grinding debris is generated during the process.
