Norton 66253044169 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253044169 is a Type 1 straight surface grinding wheel engineered for precision stock removal and surface finishing on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 8 inches in diameter, 3/4 inches thick, and carries a 1-1/4 inch arbor hole. The 60-grit medium-grade specification suits general-purpose surface grinding where controlled material removal and consistent finish are required. Rated at a maximum of 3600 RPM, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Licensed machinists and tool-and-die professionals are the primary installers and operators.

This wheel is appropriate for shop environments handling a wide range of metals. Stated material applications include 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a solid choice for production grinding operations where a medium-grade, vitrified-bond wheel delivers repeatable results across varied workpiece materials. The gray, non-tapered, non-recessed profile simplifies mounting and dressing on standard surface grinder spindles.

Key Features

• Aluminum oxide abrasive with vitrified bond for durability and consistent cut rate
• 60 grit, medium grade (Hardness Code I) for balanced stock removal and finish quality
• Type 1 straight wheel profile with no recess and no taper for straightforward mounting
• 8 inches diameter x 3/4 inches thick x 1-1/4 inches arbor hole — standard surface grinder sizing
• Maximum operating speed of 3600 RPM
• Porous structure aids coolant flow and chip clearance during wet or dry grinding
• Series specification 32A60-IVBE for direct cross-reference and replacement ordering

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications stated by the manufacturer include 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Mounting and dressing of grinding wheels should be performed by a qualified machinist or grinding machine operator following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the machine before changing wheels. Never exceed the maximum operating speed of 3600 RPM; verify spindle speed before starting.
