Norton 66253019348 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253019348 is a Type 1 surface grinding wheel engineered for demanding material removal on hard ferrous metals and specialty alloys. Built on a ceramic abrasive grain with a vitrified bond, it delivers consistent cut rates and long wheel life under wet grinding conditions. The wheel measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole. At 60 grit and H hardness (medium-soft grade), it balances aggressive stock removal with controlled surface finish. Maximum operating speed is 3600 RPM. Licensed professionals in precision machining and tool grinding environments install this wheel in surface grinder and cylindrical grinder applications.

This wheel is suited for wet-operation surface grinding of 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Typical install scenarios include production surface grinders and CNC cutting tool machines in job shops, toolrooms, and industrial maintenance settings. The 3SG series ceramic grain is semi-friable, meaning it fractures to expose fresh cutting edges during use, extending effective wheel life on difficult-to-grind materials without excessive heat buildup at the workpiece.

Key Features

• Ceramic abrasive grain with vitrified bond for consistent cut rate and long service life
• 60 grit, H hardness (medium-soft) for aggressive stock removal on hard alloys
• Porous wheel structure supports wet grinding and improved coolant delivery
• Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines
• Semi-friable grain continuously self-sharpens to reduce glazing between dresses
• Purple wheel color identifies the 3SG series for quick visual identification in the shop

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, 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 and OSHA 29 CFR 1910.215 guarding requirements. Inspect the wheel for cracks or chips using the ring test before mounting. Power down and lock out the grinder before installing or removing wheels. Never exceed the rated 3600 RPM maximum operating speed, and always use the correct flange size and blotter paper when mounting.
