Norton 66252843258 Cut-off Wheel 20 in Type 1 Zirconia

Product Description

The NORTON 66252843258 is a Type 1 resinoid-bonded cut-off wheel designed for aggressive cutting on steel and stainless steel using stationary abrasive cutting tools. Built with a zirconia alumina abrasive grain at 30 grit, this wheel delivers fast, free-cutting action with extended wheel life compared to standard aluminum oxide. The wheel measures 20 inches in diameter, 5/32 inches thick, and features a 1-inch arbor hole. Both sides are reinforced for added durability and operator safety under load. Maximum rated speed is 2,710 RPM. At 5.30 pounds, this is a full-size wheel suited to high-volume production and fabrication cutting environments.

This cut-off wheel is intended for use with stationary cutting machines in metalworking, fabrication, and industrial maintenance applications. It is well suited for cutting structural steel, pipe, bar stock, tube, and stainless steel components where a clean, efficient cut is required. The NORTON Bluefire Free Cut specification indicates this wheel is formulated for cooler cutting action, reducing heat buildup at the cut zone. Typical users include metal fabricators, pipe fitters, ironworkers, and industrial maintenance technicians operating stationary abrasive saws.

Key Features

• Zirconia alumina abrasive grain at 30 grit for fast, free-cutting performance on steel and stainless steel
• Type 1 (Type 01/41) flat wheel profile for straight, precise cuts on stationary machines
• Both sides reinforced with resinoid bond for structural integrity under cutting loads
• Bluefire Free Cut formulation reduces heat at the cut zone, extending wheel and workpiece life
• 2,710 RPM maximum rated speed — verify machine RPM before mounting
• 20-inch diameter with 1-inch arbor hole fits standard stationary abrasive cutoff saws

Compatibility

Designed for use with stationary abrasive cutoff tools rated for Type 1 wheels up to 20 inches in diameter. Suitable for cutting steel and stainless steel stock.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for abrasive wheels. Power down and lock out the machine before mounting or changing wheels. Confirm the machine spindle speed does not exceed the 2,710 RPM maximum rating stamped on the wheel — never operate above the rated speed. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately.
