Bullard 53433 Type 1 Cut-off Wheel 4x1/8x3/8 Metal

Product Description

The BULLARD 53433 is a Type 1 small-diameter cut-off wheel engineered for straight, fast cutting on metal and stainless steel. Measuring 4 inches in diameter with a 1/8-inch thickness and a 3/8-inch arbor bore, this wheel mounts on both electric and pneumatic angle grinders. It is built for trade environments where consistent performance across multiple metal applications is required. HVAC fabricators, pipefitters, plumbers, and general mechanical contractors reach for wheels like this when cutting conduit, pipe, strut, and sheet metal stock on the job site.

The 53433 is suited for residential and commercial service work involving metal cutting tasks. Its Type 1 flat profile is the standard geometry for depressed-center and straight grinder use on ferrous and non-ferrous metals, including stainless steel. The Speedster design prioritizes cutting speed without sacrificing wheel life, making it a practical choice for high-volume cutting tasks in the shop or field.

Installation Notes

Cut-off wheels must be installed and operated by personnel following ANSI B7.1 safe-use standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and never exceed the maximum RPM marked on the wheel. Ensure the grinder guard is in place and wear appropriate PPE including face shield and gloves. Do not use a cut-off wheel for grinding or side-loading.
