Our take on the Milwaukee 6142-30 4-1/2" SAG PADDLE, LOCK-ON

The Milwaukee 6142-30 is a 4-1/2 inch angle grinder with a paddle switch and lock-on, built for cutting and grinding metal, masonry and tile. Its 11-amp motor and 11,000 RPM top speed put it in line with other corded 4-1/2 inch grinders, and the paddle switch with lock-on lets you keep it running through long cuts. It suits welders, fabricators and contractors who want a simple, tough corded grinder. It is heavier and louder than compact grinders, and it has no variable speed or tool-free guard adjustment.

Milwaukee 6142-30 4-1/2" SAG PADDLE, LOCK-ON

Questions and answers

Is the 6142-30 good for cutting metal?
Yes. The 11-amp motor and 11,000 RPM speed handle cutoff wheels in steel, rebar and pipe well. Use the correct wheel and guard for the material.
Does it have a lock-on switch?
Yes. The paddle switch has a lock-on so the grinder keeps running during long cuts and grinds without holding the paddle.
Can I use it for concrete or masonry?
Yes, with a masonry grinding or cutting wheel and the guard in place. It is a dry grinder, so dust control matters.
Does it have variable speed?
No. It runs at a single speed, so polishing and delicate work are better suited to a variable-speed grinder.
What wheels fit it?
It takes 4-1/2 inch wheels with a 5/8-11 arbor, the common size for US angle grinders.
Is it a good choice over a cordless grinder?
If you work near power, the corded motor gives constant power with no battery swaps. Cordless models are better for remote sites.
