Norton 66253261811 Aluminum Oxide Cutoff Wheel 12 in 60 Grit

Product Description

The NORTON 66253261811 is a 12-inch aluminum oxide reinforced cutoff wheel designed for aggressive cutting of steel on stationary grinders. Built to a Type 1 (flat) profile, it measures 12 inches in diameter, 0.060 inches thick, and accepts a 1-inch arbor hole. The wheel is bonded with a resinoid bond and carries a hardness code of O, indicating a medium-hard grade suited for general-purpose ferrous metal cutting. At 60 grit, it delivers fast, consistent cuts. The reinforced construction — sides reinforced — adds structural integrity under the lateral stresses common in production cutting environments. Rated to a maximum of 5,095 RPM, it is sized for stationary grinder applications. Weight is approximately 0.5 pounds.

This cutoff wheel is intended for stationary grinder setups in fabrication shops, maintenance facilities, and production environments where repeatable steel cuts are required. Its aluminum oxide abrasive and resinoid bond make it a standard choice for cutting mild steel, structural steel, and similar ferrous materials. The Type 1 flat geometry is appropriate for straight cutting operations rather than grinding or notching. The specification designation A60-OBNA2 identifies the abrasive type, grit, hardness, and bond system for techs sourcing to a specific wheel spec.

Key Features

• 12-inch diameter Type 1 (01/41) flat cutoff wheel profile for stationary grinder use
• 60 grit aluminum oxide abrasive for fast ferrous metal cutting
• Resinoid bond with hardness code O for consistent cut performance on steel
• Sides reinforced construction for added structural integrity under load
• 1-inch arbor hole fits standard stationary grinder spindles
• Rated to 5,095 RPM maximum operating speed

Compatibility

Designed for use with stationary grinders. Application is rated for steel cutting. Wheel specification A60-OBNA2 confirms abrasive, grit, hardness, and bond for shops sourcing to a defined spec.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test when applicable. Power down and lockout the grinder before changing wheels. Never exceed the maximum operating speed of 5,095 RPM printed on the wheel blotter.
