Norton 66252838161 Surface Grinding Wheel 60 Grit 6 in

Product Description

The NORTON 66252838161 is a Type 1 vitrified silicon carbide surface grinding wheel rated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The wheel measures 6 inches in diameter and 1 inch thick with a 1-1/4 inch arbor hole, making it a standard fit for bench and pedestal surface grinding setups. At 60 grit with an I hardness code (medium grade), it delivers controlled material removal suitable for non-ferrous metals, cast iron, masonry, and natural stone. The vitrified bond provides rigidity and open porosity for consistent chip clearance. Maximum operating speed is 4,140 RPM. Weight is 1.35 pounds.

This wheel is built for professional grinding operations across a range of materials including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It suits trade shops and maintenance environments where a reliable, medium-grit silicon carbide wheel is needed for ferrous and non-ferrous surface work. The 39C series designation indicates a green silicon carbide formulation, which performs well on harder, brittle, and low-tensile-strength materials. It is non-porous and non-tapered with no recess.

Key Features

• Type 1 flat wheel profile — no recess, no taper for straightforward mounting
• 60 grit medium-grade cut for controlled stock removal on non-ferrous and hard materials
• I hardness vitrified bond resists glazing and maintains wheel integrity under load
• Silicon carbide abrasive (39C series) suited for stainless, titanium, aluminum, masonry, and natural stone
• 4,140 RPM maximum operating speed
• Green silicon carbide color coding for quick identification on the shop floor

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible materials include 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone.

Installation Notes

Wheel mounting and dressing should be performed by a qualified grinding machine operator following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or changing wheels. Inspect the wheel for cracks or chips before installation — never mount a damaged wheel. Verify spindle RPM does not exceed the 4,140 RPM maximum rating marked on the wheel.
