Norton 66243530246 Type 11 Grinding Wheel 46 Grit

Product Description

The NORTON 66243530246 is a Type 11 vitrified aluminum oxide grinding wheel designed for precision grinding and tool dressing applications. Built to specification 32A46-KVBE, it features 46 grit aluminum oxide abrasive bonded with a vitrified bond for consistent stock removal and durability under load. The wheel carries a K hardness code rated as Medium, which balances abrasive retention with controlled breakdown. Rated to a maximum of 5,730 RPM, it suits bench grinders and pedestal grinders used in tool rooms, maintenance shops, and fabrication environments. Licensed tradespeople and tool-room machinists are the primary installers and operators of this wheel type.

This grinding wheel is suited for bench or pedestal grinder applications requiring a cup-style Type 11 form. The 4-inch diameter and 1-1/2-inch overall thickness make it appropriate for grinding high-speed steel tooling, carbide-tipped tools, and general ferrous workpieces. The 1/4-inch face width provides a narrow contact zone for controlled material removal. It is commonly used in HVAC, plumbing, and electrical trade shops for maintaining cutting tools and custom-fitting metal components on the bench before installation.

Key Features

• 5,730 RPM maximum rating suitable for standard bench and pedestal grinders
• Gray, non-porous wheel construction per specification 32A46-KVBE

Compatibility

Designed as an OEM-style replacement or standard-service grinding wheel for bench and pedestal grinders that accept a Type 11 cup wheel with a 1-1/4-inch arbor hole and a 4-inch diameter.

Installation Notes

Grinding wheel mounting should be performed by a qualified operator following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test; do not mount a damaged wheel. Never exceed the 5,730 RPM maximum speed rating marked on the wheel.
