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.

Key Features

• Type 1 flat wheel profile for straight, on-axis cutting with standard angle grinders
• 4-inch diameter with 1/16-inch thickness for a thin kerf and reduced material waste
• 3/8-inch arbor hole fits common small-diameter electric and air grinder spindles
• 25,450 RPM maximum operating speed rating

• Sold in a box of 25 wheels for job-site supply

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.
