Designed to meet the needs of landscape maintenance professionals, our M18 FUEL™ String Trimmer kit w/ QUIK-LOK™ provides you with the power to clear thick brush, reaches full throttle in under 1 second, and features a balanced design which increases user control. The cordless string trimmer is made up of two components – the M18 FUEL™ Power Head w/ QUIK-LOK™ and QUIK-LOK™ String Trimmer Attachment. This M18 FUEL™ Power Head, part of the M18 FUEL™ QUIK-LOK™ Attachment System, is compatible with multiple attachments such as our Edger, Articulating Hedge Trimmer, and Pole Saw attachment.

The motor is positioned in the rear of the trimmer to provide the best combination of power, balance, and maneuverability. REDLINK PLUS™ intelligence gives you maximum performance while protecting from overload, overheating and over discharge. The advanced electronic package also delivers instantaneous throttle response, high and low speeds, and a variable speed trigger giving you ultimate control over the power range. The M18™ REDLITHIUM™ HIGH OUTPUT XC8.0 Battery (sold separately) gives you best in class performance and run-time in all applications.
