Product Specification
4-1/2" X .040" X 7/8" T1 PREMIUM THIN CUT-OFF WHEEL - 25 PACK
Benchmark Abrasives 4-1/2" x .040" x 7/8" T1 premium thin cut-off wheels are built for fast, precise metal cutting on one of the most common angle grinder sizes in fabrication and metalworking. The ultra-thin .040" profile creates a narrow kerf with minimal material removal, making it an excellent choice when cutting speed, control, and efficient sectioning matter.
Made with aluminum oxide abrasive grain, these flat Type 1 wheels are designed for cutting steel, stainless steel, and other approved metals. The 4-1/2" diameter provides the reach needed for everyday fabrication while staying compact and maneuverable for tubing, sheet metal, fasteners, weldments, automotive work, and general repair.
With a 7/8" arbor, this wheel is designed for compatible 4-1/2" angle grinders equipped with the correct Type 1 cut-off guard and mounting hardware. Pair it with the Benchmark Abrasives 4-1/2" angle grinder for a complete Benchmark cutting setup when the wheel, guard, flanges, and operating conditions are properly matched.
Bottom line, these cut off wheels offer LESS cutting resistance for fast work, LESS work piece waste, LESS vibration, LESS burrs and sparks and LESS dust than the competition
