Norton 66253149729 Surface Grinding Wheel 60 Grit 10 in

Product Description

The NORTON 66253149729 is a Type 1 straight surface grinding wheel engineered for precision stock removal on ferrous and non-ferrous metals. Built with an aluminum oxide abrasive grain and a vitrified bond, this wheel delivers consistent cutting action and open-pore structure suited for wet or dry surface grinding operations. It measures 10 inches in diameter, 1/2 inch thick, with a 3-inch arbor hole. Hardness is rated J (medium) with a 60-grit designation, making it appropriate for moderate material removal where surface finish and wheel life are balanced. Maximum operating speed is 2,485 RPM. Licensed machinists, tool-and-die shops, and grinding specialists are the primary installers and users.

This wheel is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, vitrified structure allows coolant penetration and chip clearance, reducing heat buildup during aggressive passes on harder alloys. The gray, non-tapered, non-recessed Type 1 profile fits standard surface grinder spindle setups with a 3-inch bore.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled cut rate
• Type 1 straight wheel profile with no recess and no taper for universal surface grinder fitment
• 60-grit, J-hardness (medium) combination balances stock removal with wheel longevity
• Porous wheel construction promotes coolant flow and chip evacuation
• Rated to 2,485 RPM maximum operating speed
• Series designation 32A60-JVBE confirms OEM-grade specification compliance

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a Type 1 straight wheel with a 3-inch arbor bore. Suitable for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Mounting and dressing of grinding wheels must be performed by a qualified machinist or grinding specialist following ANSI B11.9 safety standards. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI procedures. Never exceed the 2,485 RPM maximum rated speed marked on the wheel.
