Norton 076607-03987 Type 1 Cut-off Blade 4x.040x5/8

Product Description

The NORTON 076607-03987 is a Type 1 right angle cut-off blade engineered for cutting metal using an aluminum oxide abrasive bond. Measuring 4 inches in diameter by 0.040 inches thick with a 5/8-inch arbor bore, this thin-kerf wheel delivers fast, clean cuts on ferrous metals with minimal material loss. The aluminum oxide grain is well-suited to steel and general-purpose metal fabrication. At a maximum rated speed of 15,280 RPM, it is designed for use on standard 4-inch right angle grinders found throughout fabrication shops, jobsites, and service vehicles. This blade is sold in packs and is a practical choice for high-volume cutting applications.

This cut-off blade is used in metal cutting tasks across HVAC, plumbing, electrical, and general fabrication trades. Its 0.040-inch thickness minimizes drag and heat buildup during cutting, making it efficient for slicing conduit, pipe, strut, sheet metal, and threaded rod. The Type 1 flat profile is the standard configuration for right angle cut-off work and is compatible with guards and flanges designed for that geometry.

Installation Notes

Installation and use should be performed by qualified personnel familiar with abrasive wheel safety requirements per ANSI B7.1 standards. Always inspect the wheel for cracks or damage before mounting and never exceed the maximum rated RPM marked on the wheel. Power down and disconnect the grinder from its power source before changing wheels. Ensure the wheel guard is in place and properly adjusted before resuming cutting operations.
