Bullard 53413 Type 1 Cut-off Wheel 4in Metal 25450 Rpm

Product Description

The BULLARD 53413 is a Type 1 small-diameter cut-off wheel designed for use with electric and air grinders in metal cutting applications. Measuring 4 inches in diameter with a 1/16-inch thickness and a 3/8-inch arbor hole, this wheel is rated at 25,450 RPM and carries a 24-grit designation. The thin kerf profile allows fast, straight cuts through sheet metal and general metal stock. Licensed HVAC technicians, plumbers, electricians, and other trade professionals routinely reach for small-diameter cut-off wheels when working in tight spaces or on pipe, conduit, and sheet metal. The wheel is sold in a box quantity of 25.

These Type 1 cut-off wheels are suited for a wide range of metal cutting tasks in both residential and commercial trade environments. Typical applications include cutting mild steel, sheet metal, metal pipe, and angle iron using 4-inch electric angle grinders or pneumatic die grinders. The 1/16-inch thickness minimizes material loss at the cut line, making it practical for precise trim cuts on conduit, strut channel, and metal framing components during installation work.

Compatibility

Designed for use with 4-inch electric angle grinders and pneumatic air grinders that accept a 3/8-inch arbor. Verify that the grinder's no-load RPM rating does not exceed the 25,450 RPM maximum speed marked on the wheel before installation.

Installation Notes

Cut-off wheel mounting and use should comply with ANSI B7.1 safe-use standards for abrasive wheels. Always confirm the grinder is unplugged or the air supply is disconnected before mounting or removing a wheel. Do not exceed the maximum RPM rating stamped on the wheel, and inspect each wheel for cracks or chips before use. Appropriate eye protection and a face shield are required when operating abrasive cut-off wheels.
