Norton 66253364100 Surface Grinding Wheel 60 Grit 14 in

Product Description

The NORTON 66253364100 is a Type 1 flat surface grinding wheel built for demanding material removal on hard ferrous metals and exotic alloys. Measuring 14 inches in diameter and 1-1/2 inches thick with a 5-inch arbor hole, this wheel uses a ceramic abrasive grain bonded in a vitrified matrix rated at 1800 RPM maximum. The 60-grit, I-hardness (medium) specification delivers an aggressive cut with controlled wear, making it a go-to choice for production grinding operations where stock removal rate and wheel life both matter. At 15.5 pounds, the wheel has the mass expected of a production-grade tool for horizontal spindle surface grinders.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications in job shop and production environments. Designed to handle 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron, it covers a broad range of workpiece materials commonly encountered in tool rooms, machine shops, and heavy manufacturing. The porous, semi-friable ceramic grain structure promotes cool cutting, which is particularly valuable when grinding heat-sensitive materials such as titanium and stainless.

Key Features

• 60 grit, I hardness (medium grade) for aggressive stock removal with moderate wheel wear
• Porous and semi-friable construction promotes cool cutting on heat-sensitive alloys
• Rated to 1800 RPM maximum operating speed
• Approved material applications include stainless steel, tool steels, titanium, super alloys, and iron grades

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, 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 safety standards for grinding machines. Always inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Power down and lock out the machine before changing wheels, confirm the spindle speed does not exceed the 1800 RPM maximum marked on the wheel, and use the correct flanges and blotters sized for a 5-inch arbor hole. Ring-test the wheel per OSHA and ANSI standards before initial use.
