Norton 66253464836 Surface Grinding Wheel 16in 60 Grit

Product Description

The NORTON 66253464836 is a Type 1 surface grinding wheel engineered for high-stock-removal operations on ferrous and non-ferrous materials. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and thermal stability across extended grinding cycles. The wheel measures 16 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and weighs 10.66 pounds. The 60-grit, J-hardness (medium grade) specification suits production grinding where surface finish and dimensional accuracy must be balanced. Rated at a maximum of 2,030 RPM, this wheel is appropriate for CNC cutting tool machines, cylindrical grinders, and surface grinders in professional shop environments.

This wheel is suited for flat and surface grinding applications in industrial and production machine shops. Material compatibility includes 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The vitrified bond and porous structure promote coolant flow and chip clearance, making this wheel effective for continuous-duty grinding on surface grinder tables and cylindrical grinder setups. It is identified by the specification code 32A60-J8VBE and belongs to the NORTON 32A Type 1 series.

Key Features

• Aluminum oxide abrasive for reliable cutting on steels, cast iron, and aluminum
• Vitrified bond with porous structure for chip clearance and thermal management
• 60 grit, J hardness (medium grade) for balanced stock removal and finish
• Type 1 straight wheel profile, no recess, no taper
• Rated to 2,030 RPM maximum operating speed
• Specification code 32A60-J8VBE for direct cross-reference

Compatibility

Designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders requiring a Type 1 straight wheel with a 5-inch arbor hole and 16-inch diameter. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Wheel mounting and dressing should be performed by a qualified grinding machine operator or machinist following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards for abrasive wheel machinery. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 2,030 RPM maximum speed rating stamped on the wheel.
