Milwaukee M18 FUEL 4-1/2"/5" Braking Grinder vs Milwaukee 6142-30 Angle Grinder

Buy the M18 FUEL if you work away from an outlet or want one grinder that covers most jobs; its brushless motor matches 11A corded power, spins at 8,500 RPM, and adds a braking stop, electronic clutch kickback protection and overload protection. Buy the 6142-30 if you grind at a bench or in a shop with power, want the higher 11,000 RPM and a lock-on paddle for long sessions, and prefer a simple corded tool with a 5-year warranty. Owners rate the M18 highly (4.7 from 198 ratings) and praise its power and run time; the corded unit is the simpler, lighter-duty-feeling tool but has no battery to manage.

• Choose the M18 FUEL if you need cordless freedom, a brake that stops the wheel fast, and kickback protection on site.
• Choose the 6142-30 if you work near an outlet and want a lock-on paddle, higher RPM and a 5-year warranty at lower complexity.
