Milwaukee 6142-30 4.5 Inch 11A Small Angle Grinder Corded

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 6142-30 is a corded small angle grinder built for industrial-grade grinding, cutting, and surface preparation. Powered by a 1,400 MWO motor drawing 11 amps, it delivers consistent performance through demanding material removal tasks. The 4.5-inch wheel capacity covers a wide range of discs and accessories. A soft-start feature reduces startup torque spike, while overload protection guards the motor during heavy sustained use. The grip circumference measures a full 2 inches, reducing hand fatigue during extended operation. A paddle switch with lock-on gives the operator control over sustained runtime without holding the trigger.

This grinder is suited for metal fabrication shops, mechanical contractors, and industrial maintenance crews. Its electronic clutch helps prevent wheel bind-up and extends tool life when cutting or grinding ferrous and non-ferrous materials. The line lock-out feature prevents automatic restart after a power interruption, an important safety characteristic in continuous-duty shop environments. The tool-free, burst-resistant adjustable guard allows fast guard repositioning or removal without hand tools. Hubbed accessories can be swapped without a wrench. The unit ships with a flange, grinding wheel, side handle, spanner wrench, Type 27 guard, and contractor bag.

Installation Notes

Installation and operation should be performed by qualified trade professionals familiar with portable abrasive tools and applicable OSHA abrasive wheel safety standards.

Inspect the grinding wheel for cracks or damage before each use and confirm wheel RPM rating meets or exceeds the tool spindle speed. Ensure the side handle is properly installed before use to maintain two-handed control during operation.
