Norton 66252837840 Cut-off Wheel 12 in Aluminum Oxide

Product Description

The NORTON 66252837840 is a 12-inch aluminum oxide cut-off wheel designed for aggressive cutting in demanding trade applications. Built as a Type 1 flat wheel with a resinoid bond and double-layer reinforcement, it delivers consistent cut depth and structural integrity under load. The wheel measures 12 inches in diameter, 1/8 inch thick, and carries a 1-inch arbor hole, with a rated maximum speed of 6,300 RPM. It is suited for use with electric and gas-powered saws and is specified under the Gemini Ductile product line, targeting ductile material cutting in field and shop environments. Contractors, pipefitters, and concrete cutters are the typical end users.

This wheel is rated for ductile material applications, making it a practical choice for cutting ductile iron pipe, ferrous metal, and similar materials encountered in plumbing, mechanical, and construction trades. Its double-layer reinforced construction provides added safety margin at operating speeds and helps resist wheel breakage during lateral stress. The resinoid bond holds abrasive grain firmly through the cut cycle, reducing grain pullout and maintaining cut efficiency. It is compatible with electric and gas-powered cut-off saws that accept a 12-inch, 1-inch arbor wheel.

Key Features

• 12-inch diameter with 1/8-inch thickness for standard cut-off saw fitment
• 1-inch arbor hole fits common electric and gas-powered saw spindles
• Aluminum oxide abrasive grain, 24 grit, for fast material removal on ductile and ferrous materials
• Double-layer reinforced construction for structural integrity at high RPM
• Resinoid bond type holds grain firmly through extended cutting cycles
• Rated to 6,300 RPM maximum operating speed

Compatibility

Designed for use with electric and gas-powered cut-off saws accepting a 12-inch wheel with a 1-inch arbor. Specified for ductile material cutting under the Gemini Ductile product line.

Installation Notes

Cut-off wheels must be installed and operated by qualified personnel following ANSI B7.1 safety standards for abrasive wheel use. Always power down and de-energize or shut off the saw before mounting or removing the wheel. Inspect the wheel for cracks, chips, or damage before each use and never exceed the rated maximum RPM stamped on the wheel. Always use the appropriate guards supplied with the saw and wear eye and face protection during operation.
