Norton 66253117830 Cutoff Wheel 10 in Aluminum Oxide Type 1

Product Description

The NORTON 66253117830 is a Type 1 (01/41) resinoid-bonded aluminum oxide cutoff wheel designed for stationary cutoff machines. It measures 10 inches in diameter and 0.063 inches thick, with a 1-1/4 inch arbor hole. The aluminum oxide abrasive and resinoid bond work together to deliver consistent cutting action on steel and soft steels rated Rc 20-30 on the Rockwell hardness scale. Rated at a maximum of 4,585 RPM, this wheel is sized for stationary shop equipment rather than handheld angle grinders. It carries the ML-410 specification designation and is non-reinforced. Metalworkers, fabricators, and maintenance technicians working with mild or soft steel stock will find this wheel well-suited for their stationary cutoff saw setups.

This wheel is intended for use on stationary cutoff tools in shop environments where precise, repeatable cuts on steel are required. It is particularly suited to soft steels in the Rc 20-30 hardness range, making it a practical choice for cutting structural steel, bar stock, tube, and similar mild steel workpieces. The 10-inch diameter and 1-1/4 inch arbor hole are standard dimensions for bench-mounted and pedestal-mounted cutoff machines commonly found in metal fabrication shops, maintenance departments, and trade training facilities.

Key Features

• 10-inch diameter with 0.063-inch thickness for clean, narrow kerf cuts on steel
• 1-1/4 inch arbor hole fits standard stationary cutoff machine spindles
• Aluminum oxide abrasive grain suited for soft steels (Rc 20-30)
• Resinoid bond provides controlled hardness and consistent wheel wear
• Type 1 (01/41) flat wheel profile for straight cutoff operations
• ML-410 specification designation for verified performance standards

Compatibility

Designed for use with stationary cutoff tools. The 10-inch diameter and 1-1/4 inch arbor hole fit standard bench-mounted and pedestal-mounted cutoff machines. Rated for soft steels (Rc 20-30) per the ML-410 specification.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Always power down and lock out the machine before mounting or removing a cutoff wheel. Verify that the machine spindle speed does not exceed the 4,585 RPM maximum rating marked on the wheel before operation. Inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safe practices for the use, care, and protection of abrasive wheels.
