Norton 66253246824 Surface Grinding Wheel 60 Grit 7in

Product Description

The NORTON 66253246824 is a Type 1 surface grinding wheel engineered for precision flat and surface grinding applications. Built around an aluminum oxide abrasive bonded with a vitrified bond system, this wheel carries a 60 grit, medium grade (Hardness Code L) specification suited to aggressive stock removal on ferrous and non-ferrous metals. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and is rated to a maximum of 3,600 RPM. At 2.86 pounds, it is sized for standard surface grinder spindles. Licensed HVAC, mechanical, and machining professionals specify this wheel for toolroom and production grinding work.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. Confirmed material applications include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Series 32A Type 1 designation identifies it as a straight-profile, non-recessed wheel with no taper, making it straightforward to mount on standard surface grinder arbors. It is sold individually with a minimum order quantity of one.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cut rates
• 60 grit, medium grade (Hardness Code L) for balanced stock removal and surface finish
• Type 1 straight profile with no recess and no taper for direct arbor mounting
• Rated to 3,600 RPM maximum operating speed
• Confirmed compatible with multiple ferrous and non-ferrous workpiece materials including stainless, carbon steels, and cast iron
• Non-porous bond structure supports coolant use in wet grinding setups

Compatibility

Confirmed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron workpieces.

Installation Notes

Mounting and dressing of grinding wheels should be performed by a qualified machinist or toolroom technician following ANSI B11.9 and OSHA 29 CFR 1910.215 guarding requirements. Always perform a ring test before mounting and confirm the spindle speed does not exceed the 3,600 RPM wheel rating. Power down and lock out the grinder before changing wheels. Never exceed the rated maximum RPM; operating above this limit creates a wheel burst hazard.
