Norton 66252941314 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 66252941314 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous materials. It measures 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole. The wheel is constructed with aluminum oxide abrasive bonded in a vitrified matrix, producing a consistently porous structure that resists loading and maintains a free-cutting action throughout its service life. Rated at a maximum of 3,600 RPM and graded medium hardness (Hardness Code H), it is suitable for production surface grinding, tool room work, and CNC grinding operations performed by machinists and tool and die professionals.

This wheel is well suited for flat and surface grinding applications in both job shop and production environments. Its aluminum oxide grain performs effectively on 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use on surface grinders and cylindrical grinders, as well as CNC cutting tool machines. The 32A60-HVBEP specification identifies the full bond, grade, and structure designation for this wheel in the Norton 32A Type 1 series.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous and non-ferrous metals
• Vitrified bond provides rigidity, form-holding, and resistance to coolant degradation
• Porous wheel structure reduces loading and extends wheel life between dressings
• Medium grade (Hardness Code H) balances material removal rate with surface finish
• Type 1 flat wheel profile fits standard surface grinder and cylindrical grinder spindles
• Full specification designation 32A60-HVBEP for precise wheel matching and reorder

Compatibility

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

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding technician following ANSI B11.9 safety standards for grinding machines. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3,600. Power down and lock out the machine before changing wheels, and confirm the arbor hole fits the spindle without forcing. Appropriate eye protection and machine guarding are required during operation.
