Norton 66253261910 Cutoff Wheel 12 in Aluminum Oxide 60 Grit

Product Description

The NORTON 66253261910 is a Type 1 flat cutoff wheel designed for stationary grinder applications. Built with aluminum oxide abrasive and a resinoid bond, this 12-inch diameter wheel delivers consistent, controlled cutting on steel. At 0.075 inches thick, it produces narrow kerfs that minimize material loss and reduce heat buildup during cuts. Both sides are reinforced for added structural integrity under load. The wheel is rated to a maximum of 5,095 RPM. At 0.5 pounds, it is a straightforward drop-in consumable for stationary grinding setups. Grinding and fabrication professionals working with structural steel, pipe, and bar stock will find this wheel a reliable production-floor or shop option.

This cutoff wheel is suited for stationary grinder use in metalworking shops, fabrication facilities, and maintenance departments. The aluminum oxide grain and 60-grit designation make it appropriate for general-purpose steel cutting where a balance of stock removal rate and cut quality is needed. The 1-inch arbor hole is a standard fit for most stationary grinder spindles. The A60-OBNA2 specification grade confirms this is a production-class wheel built to consistent dimensional and hardness tolerances. Typical applications include cutting steel bar, tube, angle iron, and similar ferrous stock.

Compatibility

Designed for use with stationary grinders accepting a 12-inch diameter, Type 1 cutoff wheel with a 1-inch arbor hole. Rated for cutting steel.

Installation Notes

Installation and wheel changes should be performed by qualified personnel in accordance with ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never exceed the marked maximum RPM. Ensure the spindle speed of the stationary grinder does not exceed 5,095 RPM before operation.
