Milwaukee M18 FUEL 4-1/2"/5" Braking Grinder vs Milwaukee 6146-30 Angle Grinder

Buy the M18 FUEL if you work away from an outlet or want one grinder across the M18 system; buy the 6146-30 if you grind hard all day indoors and never want to think about batteries. The cordless matches 11A corded power and adds a braking stop, tool-free guard and accessory changes, and an electronic clutch, while the corded unit runs at 11,000 RPM with no battery to recharge. Owners rate the M18 FUEL well (4.7 from 198 ratings); the 6146-30 is a simpler, heavier corded tool with fewer convenience features.

• Choose the M18 FUEL if you want corded-class cutting without a cord, a brake that stops the wheel fast, and tool-free guard and accessory changes.
• Choose the 6146-30 if you grind for long stretches at a bench or in a shop where power is always available and you want the higher 11,000 RPM spindle speed.
