Norton 69078627993 Cut-off Wheel 20in Zirconia Alumina

Product Description

The NORTON 69078627993 is a heavy-duty Type 1 (01/41) resinoid-bonded cut-off wheel built for demanding stationary grinder applications. Measuring 20 inches in diameter and 3/16 inches thick with a 1-inch arbor hole, this wheel is constructed from zirconia alumina abrasive with reinforced sides for added durability under load. It carries a maximum operating speed of 2710 RPM. The NZ Foundry Long Life designation indicates this wheel is engineered for extended service life in high-volume cutting environments. HVAC fabricators, pipefitters, ironworkers, and metal fabrication shops are the primary installers and users of this wheel.

This cut-off wheel is designed for use with stationary grinders in industrial and commercial fabrication settings. Its zirconia alumina abrasive construction is well suited to aggressive cutting of ferrous metals in production or maintenance environments where frequent, repeated cuts are required. The large 20-inch diameter makes it appropriate for fixed floor-standing or bench-mounted grinder setups rather than portable angle grinders.

Key Features

• 20-inch diameter with 3/16-inch thickness for straight, controlled cuts
• 1-inch arbor hole fits standard stationary grinder spindles
• Zirconia alumina abrasive for aggressive stock removal and extended wheel life
• Resinoid bond provides durability and consistent cut performance
• Both sides reinforced for added structural integrity under operating stress
• NZ Foundry Long Life specification for high-volume cutting applications

Compatibility

Designed for use with stationary grinders rated to accept a 20-inch diameter Type 1 cut-off wheel with a 1-inch arbor hole and a maximum operating speed of at least 2710 RPM. Rated for cutting steel and stainless steel.

Installation Notes

This wheel must be mounted by qualified personnel on a stationary grinder confirmed to operate at or below 2710 RPM. Before mounting, power down and lock out the grinder per OSHA lockout/tagout procedures. Inspect the wheel for cracks or damage before each use and never exceed the marked maximum RPM. Appropriate eye protection, face shields, and guarding must be in place before operating.
