Norton 66253249600 Cut-off Wheel 12 in Zirconia Alumina

Product Description

The NORTON 66253249600 is a 12-inch Type 1 (01/41) resinoid-bonded zirconia alumina cut-off wheel designed for stationary grinder applications. At 1/8 inch thick with a 1-inch arbor hole, it delivers fast, aggressive cutting on ferrous metals. The wheel is reinforced on both sides for added structural integrity under load, and it carries a maximum rated speed of 5,095 RPM. Zirconia alumina grain self-sharpens during use, maintaining consistent cut performance on steel and stainless steel without excessive heat buildup. Licensed trade professionals and metal fabricators rely on this wheel for demanding repetitive cuts in production and foundry environments.

This cut-off wheel is suited for stationary grinder setups in industrial, fabrication, and foundry settings. The NZ Foundry All Purpose specification indicates it is engineered for continuous-duty use on structural steel, stainless steel plate, and similar ferrous stock. Its 12-inch diameter makes it appropriate for large-capacity stationary chop saws and abrasive cutoff machines rather than handheld angle grinders. Typical use cases include cutting rebar, structural angle iron, pipe, and sheet stock in metal fabrication shops and foundry operations.

Key Features

• 12-inch diameter, 1/8-inch thickness for aggressive, narrow-kerf cuts
• Zirconia alumina abrasive grain self-sharpens for sustained cutting efficiency
• Both sides reinforced with fiberglass mesh for structural integrity at speed
• Resinoid bond provides good shock resistance during cut-off operations
• Rated to 5,095 RPM for use on stationary abrasive cutoff machines
• NZ Foundry All Purpose specification suits steel and stainless steel applications

Compatibility

Designed for use with stationary grinders and abrasive cutoff machines accepting a 12-inch wheel with a 1-inch arbor hole. Rated for cutting steel and stainless steel per the NZ Foundry All Purpose designation.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate above the 5,095 RPM maximum rated speed printed on the blotter. Ensure the arbor flange and mounting hardware are clean and properly torqued before resuming operation, and always use appropriate eye protection and guarding.
