Milwaukee engineered durability into all of the new 4-1/2” Small Angle Grinders. Milwaukee’s advanced airflow system, including Debris Baffles and Multi-Port Exhaust, provides built in durability that extends tool life. Debris baffles are engineered L-shape intake vents that protect the motor and other components by deflecting debris particles out of the airflow before entering the grinder. Multi-Port Exhaust on all four sides of the gear case allow more hot air to escape, which helps cool the grinder and prevent motor burn-up.Performance. Start to Finish.
The way to complete a job successfully is to have the right tool for the application. Milwaukee offers a full range of 4-1/2” small angle grinders with power ratings from 7amp (775MWO) to 10Amp (1250MWO), allowing the user to purchase the right grinder for their application.

Productivity. Ease-of-Use.
The ability to get a job finished quickly and accurately is critical to grinder users. Milwaukee offers many features on their new 4-1/2” Small Angle Grinders that increase user productivity, including a tool-free adjustable guard and a soft grip 3-position side handle. The tool-free guard is also burst resistant – in the event of a wheel burst, positive detents hold the guard in place making it more secure and less likely to rotate. Left, right and top side handle positions provide optimal control for any application.
