Norton 66253347685 Cutoff Wheel 24 Inch Type 1

Product Description

The NORTON 66253347685 is a large-diameter Type 1 resinoid-bonded cutoff wheel designed for aggressive cutting in industrial and fabrication environments. Measuring 24 inches in diameter with a 7/32-inch thickness and a 1-3/4-inch arbor hole, this wheel uses a Zirconia Alumina abrasive grain at 24 grit for fast, cool cutting through ferrous metals. Both sides are reinforced for added structural integrity under load. With a maximum operating speed of 2,260 RPM, it is sized for stationary or large-angle cutting equipment. Licensed tradespeople and fabrication professionals working with structural steel or stainless steel components will find this wheel suited to high-demand cutting tasks.

This cutoff wheel is rated for cutting steel and stainless steel, making it appropriate for structural fabrication shops, pipe cutting operations, and heavy industrial maintenance applications. The 24-inch diameter positions it for use on large stationary cutting machines rather than handheld angle grinders. The Zirconia Alumina grain self-sharpens during use, maintaining cut rate over the life of the wheel without frequent dressing. Specification code NV24-TB75B identifies this wheel within the Norton product line for procurement and replacement reference.

Key Features

• 24-inch diameter Zirconia Alumina abrasive for fast, self-sharpening cuts on ferrous metals
• Type 1 (flat) wheel profile optimized for straight cutoff operations
• Resinoid bond with Hardness Code T provides controlled wear and consistent cut depth
• Both sides reinforced for structural durability under sustained cutting load
• 24 grit for aggressive material removal on steel and stainless steel
• Maximum operating speed of 2,260 RPM — verify machine nameplate before mounting

Compatibility

Rated for cutting steel and stainless steel per the manufacturer specification. Designed for stationary or fixed cutting equipment that accepts a 24-inch diameter, Type 1 cutoff wheel with a 1-3/4-inch arbor hole operating at or below 2,260 RPM.

Installation Notes

Mounting and operation of large-diameter cutoff wheels must comply with ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and perform a ring test per ANSI guidelines. Never exceed the maximum RPM stamped on the wheel, and always use the appropriate blade guard for the equipment.
