American Saw Mfg Co 1972920 Diamond Cut-off Wheel 4in 5pk

Product Description

The AMERICAN SAW MFG CO 1972920 is a 4-inch diamond edge cut-off wheel engineered for angle grinder use in demanding metal cutting applications. Built on advanced diamond technology under the METALMAX line, it delivers consistent cutting depth from first use to last, giving the operator better control and precision throughout the wheel's full service life. Unlike abrasive bonded wheels, it generates sparks only from the workpiece material itself, not from the wheel, and produces significantly less odor and dust residue during cuts. Rated for 1,000 or more cuts and marketed as lasting 30 times longer than standard thin bonded cut-off wheels, it is designed to reduce mid-job wheel changes and minimize downtime on the job site.

This wheel is suited for both residential and commercial trade applications wherever an angle grinder is the tool of choice. It handles a broad range of metals and is appropriate for plumbers, pipefitters, ironworkers, HVAC sheet metal mechanics, electricians, and general contractors cutting ferrous and non-ferrous stock. Recommended materials include steel, sheet metal, stainless steel, rebar, cast iron, and non-ferrous metals such as aluminum. Sold in a pack of 5 wheels, making it practical for ongoing production work or stocking a service vehicle.

Installation Notes

Installation and wheel changes should be performed by a qualified operator following the angle grinder manufacturer's guard and speed rating requirements. Confirm the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before mounting. Power down and disconnect the grinder from its power source before mounting or removing any wheel. Always inspect the wheel for cracks or damage before each use and ensure the arbor nut is properly tightened using the appropriate spanner wrench.
