Norton 69078649613 Cut-off Wheel 20 in Zirconia Alumina

Product Description

The NORTON 69078649613 is a Type 1 (flat) resinoid-bonded zirconia alumina cut-off wheel designed for aggressive cutting on steel and stainless steel. Measuring 20 inches in diameter, 3/16 inches thick, with a 1 inch arbor hole, this reinforced wheel is built for stationary grinder applications where consistent stock removal and wheel integrity under load are required. The resinoid bond and zirconia alumina grain work together to deliver fast cuts with reasonable wheel life. Both sides are reinforced to handle lateral stress during operation. Maximum rated speed is 2,710 RPM.

This wheel is intended for use on stationary grinders in fabrication shops, foundries, and heavy industrial settings. The NZ Foundry All Purpose specification indicates suitability for general-purpose cutting tasks across carbon steel and stainless steel workpieces. At 20 inches in diameter, this is a large-format wheel suited for production-scale cutting operations where smaller angle-grinder wheels are not practical. Licensed metalworking professionals and industrial fabricators are the primary installers and operators.

Key Features

• Zirconia alumina abrasive grain for fast cutting and extended wheel life on ferrous metals
• Type 1 flat wheel profile for straight, controlled cut-off operations
• Resinoid bond provides durability and resilience under continuous load
• Both sides reinforced for added structural integrity during stationary grinder use
• NZ Foundry All Purpose specification for versatile steel and stainless steel cutting
• Large 20 inch diameter suited to production and heavy-duty stationary equipment

Compatibility

Designed for use with stationary grinders accepting a 20 inch diameter, 1 inch arbor hole, Type 1 cut-off wheel with a maximum operating speed of 2,710 RPM or lower. Rated for cutting steel and stainless steel.

Installation Notes

Mounting and operation of large-diameter cut-off wheels must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always verify the grinder spindle speed does not exceed the wheel maximum of 2,710 RPM before mounting. Inspect the wheel for cracks or damage prior to installation and never use a damaged wheel. Appropriate guarding, eye protection, and face shields are required during operation.
