Norton 66252938796 Cutoff Wheel 7 in Aluminum Oxide 60 Grit

Product Description

The NORTON 66252938796 is a Type 1 (flat) resinoid-bonded aluminum oxide cutoff wheel built for aggressive cutting on steel. At 7 inches in diameter and 0.06 inches thick, it runs on stationary grinders at up to 8,730 RPM. The aluminum oxide abrasive is rated 60 grit with a hardness code of O, delivering a consistent cut on structural steel, bar stock, and similar ferrous materials. Both sides are reinforced for added integrity during cut-off operations. This wheel is a standard consumable used by fabricators, ironworkers, and maintenance technicians working with stationary angle grinders and chop-style machines.

This cutoff wheel is designed for use with stationary grinders where a 1-1/4 inch arbor hole is required. Its Type 1 flat profile makes it suited for straight, plunge-style cut-off work on steel workpieces in fabrication shops, maintenance facilities, and light industrial settings. The 0.06 inch thickness minimizes material loss at the kerf while the resinoid bond maintains wheel structure through the full cut. The specification designation A60-OBNA2 confirms the abrasive type, grit, hardness, and bond system for procurement and replacement matching.

Key Features

Compatibility

Designed for use with stationary grinders requiring a 1-1/4 inch arbor hole. Rated for cutting steel per the manufacturer application designation.

Installation Notes

Mounting and wheel changes must be performed by qualified personnel with the grinder fully de-energized and the power source locked out per OSHA lockout/tagout procedures. Inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Do not exceed the 8,730 RPM maximum speed rating stamped on the wheel. Always use the appropriate guard and personal protective equipment including a face shield when operating abrasive cutoff wheels.
