Arc Abrasives 904163803 Type 1 Cut Off Wheel 4in Box of 50

Product Description

The ARC ABRASIVES 904163803 is a Type 1 flat cut off wheel designed for fast, clean cutting across all metals. Built under the Predator line, this wheel measures 4 inches in diameter by 1/16 inches thick with a 3/8-inch arbor bore. It carries an A46T abrasive grade, balancing aggressive material removal with extended wheel life. Rated at 19,100 RPM, it is suited for use on standard angle grinders and cut off tools common in trade and fabrication environments. Each box contains 50 wheels. The self-sharpening abrasive formulation maintains a consistent cut edge throughout the wheel's life, reducing glazing and heat buildup at the cut zone.

This cut off wheel is a practical choice for metal fabrication shops, mechanical contractors, plumbers, and electricians who regularly cut ferrous and non-ferrous metals on the job. Its thin 1/16-inch kerf minimizes material loss and reduces the effort needed to complete each cut. The wheel is appropriate for use on pipe, conduit, angle iron, sheet metal, and similar materials. The 50-count box format suits service vehicles and shop storage where consistent supply is needed across multiple technicians or job sites.
