Bullard 54221 Type 1 Cut-off Wheel 12x3/32x1 Metal

Product Description

The BULLARD 54221 is a Type 1 cut-off wheel engineered for high-speed metal cutting on angle grinders and circular saws. Measuring 12 inches in diameter with a 3/32-inch thickness and a 1-inch arbor bore, this wheel is rated at 5092 RPM. The design prioritizes fast, cool, and free-cutting performance, reducing power draw on the tool motor. Flexibility built into the wheel construction allows it to handle binding and stressful cuts without fracturing, making it a reliable choice for demanding work environments. Licensed tradespeople and fabricators in maintenance departments, welding shops, and metal fabrication facilities are the primary users.

This wheel is suited for cutting metal studs, structural steel, pipe, and similar ferrous stock. It is compatible with angle grinders and circular saws configured for Type 1 cut-off wheel geometry. The 12-inch diameter makes it appropriate for larger benchtop or stationary cut-off machines as well as heavy-duty handheld grinders. Typical applications include framing with metal studs, weld prep, and general fabrication cutoff work in both shop and field settings.

Key Features

• Type 1 flat geometry for straight, plunge, and cutoff cuts on metal
• 5092 RPM maximum operating speed for high-throughput cutting
• 12-inch diameter with 3/32-inch thickness for clean, narrow kerfs
• Flexible construction reduces wheel fracture risk under binding conditions
• Low power draw design reduces motor fatigue on angle grinders and circular saws
• Suited for metal studs, structural steel, and ferrous fabrication stock

Compatibility

Designed for use on angle grinders and circular saws that accept Type 1 cut-off wheels with a 12-inch diameter and 1-inch arbor. When used on a right-angle grinder, the proper Type 1 flange must be installed to ensure safe and correct wheel seating.

Installation Notes

Mounting and use of cut-off wheels should be performed by qualified personnel familiar with ANSI B7.1 safety requirements for abrasive wheels. Inspect the wheel for cracks or chips before each use and never exceed the rated 5092 RPM. Power down and disconnect or lock out the tool before changing wheels. Always use the correct Type 1 flanges and guard for this wheel diameter and never operate without the guard in place.
