Diablo DBD045040125F Type 1 Cut-off Wheel 4-1/2 in 25 Pack

Product Description

The DIABLO DBD045040125F is a Type 1 (01/41) reinforced aluminum oxide cut-off wheel designed for fast, controlled cutting on steel and stainless steel. The wheel measures 4-1/2 inches in diameter with a 0.04-inch thickness and a 7/8-inch arbor hole. It is rated to 13,280 RPM and bonded with a resinoid bond at hardness code R, meeting A60R BF INOX specifications. The thin profile reduces heat buildup and material drag during cutting operations. This wheel ships in a package quantity of 25, making it suited for shop stocking and job-site supply. Fabricators, ironworkers, plumbers, and general contractors typically use this wheel with a 4-1/2-inch angle grinder.

This cut-off wheel is built for cutting ferrous and non-ferrous metal stock in fabrication shops, mechanical rooms, and field installations. The aluminum oxide abrasive at 60 grit delivers aggressive stock removal on mild steel, structural steel, and stainless steel. The reinforced fiberglass construction provides lateral stability and reduces breakage risk during plunge and straight cuts. It is well suited for pipe fitting, sheet metal work, and structural steel fabrication where a clean, fast cut is required without excessive wheel deflection.

Installation Notes

Always inspect the wheel for cracks or chips before mounting. Ensure the grinder is unplugged or the power source is isolated before changing wheels. Verify that the grinder spindle speed does not exceed the 13,280 RPM maximum rating stamped on the wheel. Use the appropriate guard for Type 1 cut-off wheels as required by OSHA 1910.243 and ANSI B7.1 standards, and never use this wheel for side grinding or grinding operations.
