Milwaukee 2828-21E M18 Brushless 16″ String Trimmer Kit (1) 6AH

Built for pro crews and serious property maintenance, the Milwaukee 2828-21E M18™ Brushless String Trimmer combines high torque with a lightweight build to clear thick grass and brush without slowing down. The brushless motor delivers up to 6,200 RPM (approx. 1.39 HP) and pairs with REDLINK™ Intelligence to manage power and heat for consistent cutting in dense growth. Use High for demanding passes and Low to maximize run time for routine trimming—both modes are controlled with a variable-speed trigger for precise throttle. An adjustable 14″–16″ cutting swath lets users choose between nimble trimming or faster clearing, and the Easy Load head accepts 25 ft of .080″ or 20 ft of .095″ line and reloads in under 30 seconds. Included is the M18™ REDLITHIUM™ HIGH OUTPUT™ XC6.0 battery and a dual-voltage charger, so you’re ready to work out of the box—plus this tool is part of the M18™ System (300+ solutions) for battery and charger commonality across the fleet.

This cordless string trimmer is a practical upgrade from gas: less maintenance, instant starts, and strong cutting performance with .080″ or .095″ line. For weekly routes, seasonal knockdowns, or acreage cleanup, the 16″ path, quick line reload, and balanced 11.5 lb design keep productivity high with fewer stops.
