Norton 66253117828 Cutoff Wheel 9 in Aluminum Oxide Type 1

Product Description

The NORTON 66253117828 is a Type 1 flat cutoff wheel designed for precision cutting of steel on stationary tools. Built with aluminum oxide abrasive and a resinoid bond, it delivers consistent material removal on soft steels in the Rc 20-30 hardness range. The wheel measures 9 inches in diameter and 0.063 inches thick, with a 1-1/4 inch arbor hole for standard spindle fitment. It carries a maximum operating speed of 5,085 RPM and meets ML-409 specifications. At 0.308 pounds, it is a lightweight single-unit replacement suitable for regular shop rotation in metal fabrication and cutting operations.

This cutoff wheel is intended for use with stationary cutting tools in shop environments. Its aluminum oxide grain and resinoid bond make it well suited for cutting soft steels, including structural stock, pipe, and bar stock in the Rc 20-30 hardness range. Fabricators, maintenance technicians, and metalworkers performing repetitive straight cuts will find the 9 inch diameter and thin 0.063 inch profile appropriate for clean, efficient parting cuts with minimal kerf loss.

Key Features

• Aluminum oxide abrasive with resinoid bond for consistent cutting on soft steels
• Type 1 flat wheel profile optimized for straight parting cuts
• 0.063 inch thickness minimizes kerf and reduces material waste
• 5,085 RPM maximum operating speed rated for stationary tool use
• Non-reinforced construction for use within rated speed on compatible stationary equipment
• Meets ML-409 specification for quality and performance consistency

Compatibility

Designed for stationary cutting tools accepting a 9 inch diameter, 1-1/4 inch arbor hole Type 1 cutoff wheel. Rated for soft steels in the Rc 20-30 hardness range per manufacturer application data.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and de-energize the tool before mounting or removing the wheel. Confirm the tool spindle speed does not exceed 5,085 RPM before operation. This wheel is non-reinforced and must not be used on portable angle grinders or any application outside its rated stationary tool designation.
