Dewalt DWE4120FN Angle Grinder 4-1/2 to 5 in 12000 Rpm

Product Description

The DEWALT DWE4120FN is a corded angle grinder built for grinding, cutting, and surface preparation on metal, masonry, and concrete. It accepts 4-1/2 to 5 inch wheels on a 5/8-11 spindle and spins at 12000 RPM, delivering the wheel speed needed for aggressive material removal. Drawing 9.0 amps, this grinder produces consistent power under load. The paddle switch design gives operators direct, intuitive control without triggerlock engagement, which is a safety-preferred configuration on many job sites. Licensed electricians, ironworkers, pipefitters, and general tradespeople commonly use this tool for weld cleanup, pipe prep, and tile or masonry cutting.

The DWE4120FN is suited for both residential and commercial trade applications where a compact, full-power angle grinder is required. Typical scenarios include metal fabrication shops, HVAC rough-in work involving sheet metal, plumbing pipe preparation, and electrical conduit work. The included 5 inch Type 27 guard, side handle, hex key, and inner and outer flanges allow the tool to be put to work immediately without sourcing additional accessories. It is a practical choice when a reliable corded grinder needs to stay on a service truck or job site kit.
