Arc Abrasives 945047805W Predator Type 1 Cut-off Wheel

Product Description

The ARC ABRASIVES 945047805W Predator Type 1 cut-off wheel is a reinforced abrasive disc engineered for high-speed cutting on demanding applications. Measuring 4-1/2 inches in diameter with a 0.04-inch thickness and a 7/8-inch arbor bore, this wheel is built for precision and durability. A performance coating reduces heat buildup and loading during use, resulting in faster cuts and extended wheel life. The Type 1 flat profile makes it well-suited for right-angle grinders used in metal fabrication, pipe cutting, and structural steel work. Tradespeople in HVAC, plumbing, electrical, and general fabrication rely on this wheel for consistent results under heavy pressure.

This cut-off wheel is intended for use with 4-1/2-inch right-angle grinders in both residential and commercial trade applications. The 0.04-inch precision thickness provides refined control when making straight cuts through metal conduit, pipe, angle iron, unistrut, and similar materials. The reinforced construction handles sustained, high-pressure cutting without degrading rapidly, making it suitable for repetitive cutting tasks on job sites where throughput matters.

Key Features

• Performance coating reduces heat and loading for faster cuts and longer wheel life
• Precision 0.04-inch thickness for refined cut control
• Reinforced construction for heavy-pressure and demanding cutting applications
• Type 1 flat profile compatible with standard right-angle grinder guards
• High stability during operation reduces flex and chatter

Compatibility

Designed for use with 4-1/2-inch right-angle grinders equipped with a 7/8-inch arbor. Verify that the grinder RPM rating meets or exceeds the maximum RPM marked on the wheel before mounting.

Installation Notes

Mounting and use of cut-off wheels should follow ANSI B7.1 safety standards. Always inspect the wheel for cracks or damage before mounting, and never use a damaged wheel. Ensure the grinder is unplugged or the power source is isolated before changing wheels. Use the appropriate guard and personal protective equipment, including eye and face protection, during operation.
