Norton 66253043009 Cutoff Wheel 8in Aluminum Oxide 60 Grit

Product Description

The NORTON 66253043009 is an aluminum oxide reinforced cutoff wheel designed for aggressive cutting and parting operations on steel. Built to a Type 1 (flat) profile, it measures 8 inches in diameter and 0.06 inches thick, with a 1/2 inch arbor hole for mounting on compatible stationary grinders. The resinoid bond holds aluminum oxide abrasive grains at a 60-grit rating, delivering a balance of cut rate and surface finish suitable for ferrous metal fabrication work. Both sides of the wheel are reinforced for added structural integrity during high-speed operation. The maximum operating speed is 7,640 RPM. Licensed trades and metal fabricators working with stationary equipment will find this wheel a straightforward fit for production cutting tasks.

This cutoff wheel is intended for use with stationary grinders in shop and fabrication environments. It is well suited for cutting steel bar stock, pipe, angle iron, and similar ferrous workpieces. The 8-inch diameter and thin 0.06-inch kerf minimize material loss and heat buildup during straight cuts. At 0.5 pounds, the wheel is light enough for easy handling and spindle balancing during setup.

Key Features

• 8-inch diameter Type 1 flat profile for straight parting cuts on stationary grinders
• Aluminum oxide abrasive with 60-grit rating rated for steel applications
• Resinoid bond provides durability and consistent grain release during cutting
• Both sides reinforced for structural integrity at operating speeds up to 7,640 RPM
• Thin 0.06-inch wheel thickness reduces kerf width and heat generation
• 1/2 inch arbor hole fits standard stationary grinder spindles

Compatibility

Designed for use with stationary grinders accepting an 8-inch diameter, Type 1 cutoff wheel with a 1/2 inch arbor hole. Rated for steel cutting applications per manufacturer specification A60-OBNA2.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum speed of 7,640 RPM. Use the correct flanges and blotter paper as required by the grinder manufacturer.
