Bullard 53405 Type 1 Cut-off Wheel 4x0.040x5/8 Metal 19000 Rpm

Product Description

The BULLARD 53405 is a Type 1 small-diameter cut-off wheel engineered for cutting metal and thin-walled tubing with electric or air-powered angle grinders. It measures 4 inches in diameter, 0.040 inches thick, and accepts a 5/8-inch arbor. At a maximum operating speed of 19,000 RPM, the wheel delivers fast, straight cuts with minimal burring. The 60-grit aluminum oxide bond construction provides an aggressive cut rate while maintaining wheel life across repeated use. Fabricators, pipefitters, and mechanical contractors reach for this wheel when production cutting speed and consistent results matter on ferrous metal stock and tube.

This cut-off wheel is suited for residential and commercial fabrication work, maintenance and repair operations, and field service applications wherever grinder-based cutting is required. It performs on structural steel, pipe, conduit, and thin-walled tubing. Its compact 4-inch diameter fits standard right-angle grinders used daily by pipefitters, electricians, HVAC techs, and general metal fabricators. The wheel ships in box quantity with a minimum order of one box, making it practical for restocking job-site tool kits or shop inventory.

Key Features

• Type 1 flat wheel profile for straight, controlled cut-off operations
• 4-inch diameter with 0.040-inch thickness for thin kerf and reduced material loss
• 5/8-inch arbor bore fits most standard right-angle grinders
• 19,000 RPM maximum operating speed rated for high-speed electric and air grinders
• 60-grit construction optimized for metal and thin-walled tubing applications
• Compatible with both electric and pneumatic angle grinder platforms

Compatibility

Designed for use with electric and air-powered right-angle grinders accepting a 4-inch Type 1 cut-off wheel with a 5/8-inch arbor. Suitable for cutting metal and thin-walled tubing applications.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following the grinder manufacturer's guard and flange requirements. Always confirm the grinder's rated RPM meets or exceeds the 19,000 RPM wheel rating before mounting. Power down and disconnect the grinder from its power source before changing wheels, and inspect the wheel for cracks or chips prior to each use. ANSI B7.1 and applicable OSHA abrasive wheel standards govern safe mounting and operation of cut-off wheels.
