Norton 66253261858 Aluminum Oxide Cutoff Wheel 12 in 60 Grit

Product Description

The NORTON 66253261858 is a Type 1 flat aluminum oxide cutoff wheel designed for aggressive, straight cutting on steel. It measures 12 inches in diameter with a 0.075-inch thickness and accepts a 1-1/4-inch arbor hole, making it compatible with standard stationary grinders. The wheel is resinoid-bonded with a 60-grit aluminum oxide abrasive and carries an O hardness rating, delivering a balance of cut rate and wheel life suited to production and heavy-duty shop environments. Both sides are reinforced for added durability under lateral stress. Maximum rated speed is 5,095 RPM. This wheel is installed and operated by metalworkers, fabricators, and maintenance trades using stationary cutoff machines.

This cutoff wheel is intended for use on stationary grinders in shop and fabrication settings. It is well suited for cutting steel stock, bar stock, pipe, and structural shapes in both light industrial and heavy fabrication applications. The 12-inch diameter and 60-grit specification make it appropriate for production cutting where consistent results on ferrous metal are required. This is not a portable angle grinder wheel — it is rated for stationary equipment only.

Key Features

• 12-inch diameter Type 1 flat profile for straight cutoff work on stationary grinders
• Aluminum oxide abrasive at 60 grit for efficient material removal on steel
• Resinoid bond provides durability and resistance to shock loads during cutting
• Both sides reinforced for additional structural integrity
• O hardness grade balances wheel longevity with consistent cut performance
• 5,095 RPM maximum speed rating for stationary grinder compatibility

Compatibility

Designed for use with stationary grinders. Rated for steel cutting applications. Confirm that the host machine's operating RPM does not exceed the 5,095 RPM maximum rating before mounting.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel. Ensure the machine's spindle speed does not exceed the wheel's 5,095 RPM maximum rating, and use the correct flanges and arbor hardware as specified by the grinder manufacturer.
