Norton 69078627988 Cut-off Wheel 20 in Zirconia Alumina

Product Description

The NORTON 69078627988 is a large-diameter cut-off wheel engineered for heavy-duty stationary grinder applications. It measures 20 inches in diameter with a 5/32 inch thickness and a 1 inch arbor hole. The abrasive grain is zirconia alumina, bonded with a resinoid bond and reinforced on both sides for added structural integrity during high-stress cutting operations. The wheel carries a maximum rated speed of 2710 RPM. It is designed for use with stationary grinders and is suited for production-level cutting on ferrous and specialty metals. Licensed tradespeople and industrial maintenance professionals are the primary installers and operators of this wheel.

This cut-off wheel is well suited for cutting steel and stainless steel in fabrication shops, foundries, and industrial maintenance environments. The NZ Foundry Long Life specification indicates the wheel is formulated for extended service life under the demanding conditions found in foundry and heavy manufacturing settings. Its Type 1 (01/41) flat profile makes it appropriate for straight cut-off work on stationary equipment where wheel size and durability are critical factors.

Key Features

• 20 inch diameter suits large stationary grinder setups requiring aggressive material removal
• Zirconia alumina grain provides high cut rate and durability on steel and stainless steel
• Resinoid bond with sides reinforced construction adds safety margin at operating speed
• Type 1 (01/41) flat wheel profile for straight cut-off applications
• NZ Foundry Long Life specification for extended wheel life in heavy-duty cycles
• Maximum rated speed of 2710 RPM for stationary grinder compatibility

Compatibility

Designed for use with stationary grinders. Rated for cutting steel and stainless steel. Verify that the stationary grinder's spindle speed does not exceed the 2710 RPM maximum rating of this wheel before mounting.

Installation Notes

Installation and operation of large-diameter cut-off wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before every use and never exceed the maximum rated RPM. Appropriate personal protective equipment including a face shield, safety glasses, and hearing protection is required during operation.
