Bullard 54421 Type 1 Cut-off Wheel 14x3/32x1 Metal

Product Description

The BULLARD 54421 is a Type 1 cut-off wheel designed for high-speed metal cutting on angle grinders and circular saws. Measuring 14 inches in diameter with a 3/32-inch thickness and a 1-inch arbor bore, it operates at a maximum rated speed of 4366 RPM. The wheel is engineered to cut faster, cooler, and with less binding than standard abrasive wheels, reducing the power demand on the tool. This design makes it well suited for repetitive cutting tasks in demanding shop and field environments. Metal fabricators, maintenance technicians, and welders are the primary users of this wheel.

The BULLARD 54421 is intended for cutting metal studs and similar ferrous stock. Its flexible construction allows it to perform under stressful and binding conditions without fracturing, which is important during off-angle or constrained cuts. Typical installation scenarios include maintenance departments, welding shops, and metal fabrication facilities where consistent throughput and wheel longevity are priorities. The 14-inch diameter suits larger angle grinders and abrasive circular saws commonly found in production and fabrication settings.

Key Features

• 14-inch diameter with 3/32-inch thickness for fast, low-heat metal cuts
• 1-inch arbor bore fits standard angle grinder and abrasive saw spindles
• Maximum operating speed of 4366 RPM
• Flexible wheel construction resists fracture under binding and stressful cuts
• Optimized for metal studs and ferrous metal cutting applications
• Designed to reduce power draw on the host tool during use

Compatibility

Designed for use with angle grinders and circular saws that accept a 14-inch Type 1 cut-off wheel with a 1-inch arbor. When mounting on a right-angle grinder, a proper Type 1 flange must be used to ensure safe and correct wheel retention.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with abrasive wheel safety. Before mounting, confirm the tool spindle speed does not exceed the 4366 RPM maximum rated speed of the wheel. Always use the correct Type 1 flange when mounting on a right-angle grinder, as an incorrect flange can cause wheel failure. Inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safety guidelines for abrasive wheel operation.
