Norton 66253322099 Cutoff Wheel 12in Aluminum Oxide Type 1

Product Description

The NORTON 66253322099 is a Type 1 (01/41) flat cutoff wheel engineered for stationary abrasive cutting applications. It measures 12 inches in diameter and 0.078 inches thick, with a 1-1/4 inch arbor hole sized for standard stationary cutoff machines. The wheel uses aluminum oxide abrasive bonded with a resinoid bond in a non-reinforced construction, rated to a maximum of 3,820 RPM. This configuration delivers consistent, controlled cuts on soft steels in the Rc 20-30 hardness range, making it a standard choice for fabrication shops, maintenance facilities, and metalworking trades.

This cutoff wheel is intended for use with stationary cutoff machines rather than handheld angle grinders. Its primary application is cutting soft steels, including mild steel and other ferrous metals in the Rc 20-30 hardness range. The 12-inch diameter suits production or bench-mounted saws used in fabrication, structural steel work, and general metal shop environments. The non-reinforced resinoid bond construction is suited to the controlled cutting forces of stationary equipment rather than portable tools.

Key Features

• 12 inch diameter Type 1 flat profile for stationary cutoff saws
• Aluminum oxide abrasive with resinoid bond for consistent cut performance on soft steel
• Non-reinforced construction designed for stationary tool use
• 3,820 RPM maximum speed rating
• Optimized for soft steels in the Rc 20-30 hardness range
• Meets ML-412 specification

Compatibility

Designed for use with stationary cutoff machines accepting a 12 inch diameter, 1-1/4 inch arbor wheel. Specified for soft steels in the Rc 20-30 hardness range per ML-412 specification. Not intended for use with handheld portable grinders.

Installation Notes

Installation and wheel changes must be performed by qualified personnel with the machine fully de-energized and locked out per applicable LOTO procedures. Confirm the machine spindle speed does not exceed the 3,820 RPM maximum rating stamped on the wheel before mounting. Inspect the wheel for cracks or damage before each use and discard any wheel that shows visible defects. Do not use this non-reinforced wheel on handheld angle grinders or portable cutting tools.
