Norton 66252941488 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252941488 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of metals and hard materials. Built around a silicon carbide abrasive grain bonded in a vitrified matrix, this wheel delivers consistent, coarse-grade cutting action at up to 3600 RPM. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The vitrified bond provides rigidity and free-cutting characteristics that hold up under the heat and pressure typical of surface grinding operations. At 1.711 pounds, the wheel is sized for standard surface and cylindrical grinder spindles common in machine shops and fabrication environments.

This wheel is rated for use on 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It is designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46 grit and J hardness rating make it well suited for aggressive material removal rather than finish grinding. Fabricators, toolroom machinists, and maintenance technicians will find it applicable across a broad range of common shop materials where fast cutting and wheel longevity are priorities.

Key Features

• Silicon carbide abrasive grain for effective cutting on metals, masonry, and stone
• Vitrified bond provides rigidity and resistance to heat distortion during grinding
• 46 grit coarse grade for high material removal rates
• J hardness (medium) rating balances wheel wear against cutting aggression
• Non-porous, non-tapered, no-recess Type 1 flat wheel profile
• Rated to 3600 RPM maximum operating speed

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Series designation 37C Type 1, specification 37C46-JVMT.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the grinder before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 guidelines. Never exceed the 3600 RPM maximum speed rating marked on the wheel.
