Norton 66253117880 Cutoff Wheel 10in Aluminum Oxide Type 1

Product Description

The NORTON 66253117880 is a Type 1 (01/41) aluminum oxide cutoff wheel designed for stationary abrasive cutting tools. Measuring 10 inches in diameter and 0.063 inches thick with a 1-1/4 inch arbor hole, this wheel is built for straight, flat cutting operations at up to 3,500 RPM. The resinoid bond and aluminum oxide abrasive grain make it well-suited for cutting hard steels, including materials in the Rc 40-55 hardness range. It carries the ML-210 specification designation and is supplied as a single wheel. Fabricators, metalworkers, and tool-and-die professionals typically use this wheel with stationary chop saws and cutoff machines.

This cutoff wheel is intended for stationary tool use in industrial and fabrication environments. Its primary application is cutting steel, with a specific callout for hard steels in the Rc 40-55 hardness range. The non-reinforced, Type 1 flat profile makes it appropriate for straight plunge cuts only. It is not rated for use with angle grinders or portable handheld equipment. Shops handling structural steel, tool steel, or hardened components will find this wheel suited to their stationary cutoff operations.

Installation Notes

Mount this wheel on a stationary cutoff machine with a matching 1-1/4 inch spindle arbor. Always power down and de-energize the machine before changing wheels. Confirm the machine spindle speed does not exceed 3,500 RPM before operation, as exceeding the rated maximum RPM is a serious safety hazard. Inspect the wheel for cracks or chips prior to each use and follow applicable ANSI B7.1 safety requirements for abrasive wheel mounting and guarding.
