Norton 66252941609 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66252941609 is a Type 1 surface grinding wheel engineered for aggressive material removal on hard and non-ferrous metals. Constructed with silicon carbide abrasive grain and a vitrified bond, this wheel delivers consistent cut rates and shape retention during extended grinding operations. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, and carries a 60 grit, medium-grade (I hardness) specification rated to 3,600 RPM. The vitrified bond resists heat and loading, making it well suited for precision surface grinding where dimensional accuracy matters. Machinists, tool and die technicians, and industrial maintenance trades are the primary installers and operators of this wheel.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and job-shop environments. The silicon carbide construction makes it effective on a wide range of materials including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. The green wheel color is characteristic of silicon carbide tooling and helps operators quickly identify abrasive type on the shop floor. It is a non-porous, non-tapered, no-recess Type 1 flat wheel suited to standard straight-wheel grinding setups.

Key Features

• Silicon carbide abrasive grain for effective grinding of metals, masonry, and stone
• Vitrified bond construction provides rigidity, shape retention, and resistance to heat buildup
• 60 grit medium grade (I hardness) balances stock removal with surface finish quality
• 3,600 RPM maximum speed rating for safe use on standard surface and cylindrical grinders
• Type 1 flat wheel profile with no recess and standard 1-1/4 inch arbor hole for broad machine compatibility
• Non-porous wheel construction reduces loading when working non-ferrous and soft materials

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Verify spindle speed does not exceed the 3,600 RPM maximum rating before mounting.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified machinist or grinding technician in accordance with ANSI B11.9 and the machine manufacturer's instructions. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM marked on the wheel. Flanges, blotters, and arbor hardware must be properly sized and torqued to manufacturer specifications for the specific grinder model in use.
