Norton 66252939549 Surface Grinding Wheel 7in 60G

Product Description

The NORTON 66252939549 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous materials in industrial grinding operations. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and predictable wear characteristics across a range of surface and cylindrical grinding applications. It measures 7 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole, and carries a 60 grit, J hardness (medium grade) rating. Rated to 3600 RPM, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Series designation is 32A60-JVBE.

This wheel is appropriate for toolroom and production grinding environments where close tolerances and surface finish quality are required. Compatible 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 non-tapered, no-recess wheel with a porous structure and gray wheel color. Typical users include tool and die makers, machine shop technicians, and maintenance machinists working with surface grinders or cylindrical grinding equipment.

• No recess, no taper — straightforward Type 1 flat wheel geometry
• Series 32A60-JVBE designation for direct specification and reorder

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications listed 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

Wheel mounting should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and fully de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per standard practice. Never exceed the wheel's maximum rated RPM of 3600 under any operating condition.
