Arc Abrasives 904161403 Type 1 Cut Off Wheel 4in Box of 50

Product Description

The ARC ABRASIVES 904161403 is a Type 1 flat cut off wheel engineered for fast, clean cuts across all metal types. Measuring 4 inches in diameter by 1/16 inches thick with a 1/4-inch arbor bore, this wheel carries an A46T abrasive grade and is rated to 19,100 RPM. It is sold in a box of 50 wheels, making it a practical choice for shops and service professionals who cut frequently. The self-sharpening abrasive structure maintains a consistent cut rate throughout the wheel life, and the formulation resists heat buildup to prevent workpiece burning and discoloration.

This cut off wheel is suited for use in metalworking, fabrication, HVAC rough-in, plumbing preparation, and general trade applications where a fast, controlled metal cut is required. At 4 inches, it fits standard angle grinders and pneumatic cut off tools common on job sites. The 1/16-inch profile minimizes material loss per cut, which is useful when working with conduit, pipe, sheet metal, strut channel, and structural steel.

Installation Notes

Wheel mounting and use should follow ANSI B7.1 safety standards for abrasive wheels. Always confirm the tool's rated RPM meets or exceeds the wheel's 19,100 RPM maximum before mounting. Inspect each wheel for cracks or damage before use and never exceed the marked maximum speed. Appropriate eye protection, gloves, and guarding are required during operation.
