Norton 66252830975 Type 11 Grinding Wheel 60 Grit

Product Description

The NORTON 66252830975 is a Type 11 flaring cup grinding wheel designed for precision tool grinding and surface conditioning applications. Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal with a medium grade, 60 grit cut. It measures 5 inches in diameter with a 1-3/4 inch overall thickness and a 1/4 inch face width. The friable aluminum oxide grain breaks down during use to expose fresh cutting edges, maintaining cut rate over the life of the wheel. Rated to a maximum of 4,585 RPM, it suits bench and pedestal grinder setups operated by machinists, tool-and-die workers, and maintenance technicians.

This wheel is suited for offhand tool grinding, drill sharpening, and general bench grinder work in industrial maintenance, machine shops, and trade shop environments. The 60 grit medium grade makes it appropriate for moderate material removal on carbon steel tooling, HSS drill bits, lathe tools, and similar shop implements. The 1-1/4 inch arbor hole fits standard bench and pedestal grinder spindles commonly found in trade and production environments. The white aluminum oxide composition is a good fit for heat-sensitive tooling where minimizing workpiece burn is a priority.

Key Features

• Type 11 flaring cup wheel profile for tool and cutter grinding applications
• White aluminum oxide abrasive with vitrified bond for consistent, free-cutting action
• 60 grit medium grade balances stock removal rate with surface finish
• Friable grain structure self-dresses during use to maintain cut efficiency
• Rated to 4,585 RPM maximum operating speed
• Non-porous construction for controlled wheel wear and dimensional stability

Compatibility

Designed as a replacement-style Type 11 cup wheel for standard bench and pedestal grinders fitted with a 1-1/4 inch arbor spindle. Specification code 38A60-KVBE identifies this wheel within the Norton abrasives system for cross-reference purposes.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test; do not use a wheel that fails inspection. Ensure the machine speed does not exceed the 4,585 RPM maximum rating marked on the wheel.
