Our take on the Milwaukee 6142-30 11 Amp Corded 4-1/2" Small Angle Grinder with Lock-On Paddle Switch

The Milwaukee 6142-30 is a corded 4-1/2 in angle grinder built for professional metal and concrete work. Its 11 amp motor spins at 11,000 rpm, and tool-free accessory changes and a tool-free adjustable guard cut downtime on the job. An advanced airflow system with debris baffles is meant to keep grit out of the motor and extend its life. It is a single-speed tool, so it suits grinding and cutting tasks rather than work that needs dialed-down rpm.
