Milwaukee M18 FUEL QUIK-LOK String Trimmer Attachment — Selectable 14/16 in Swath, Easy-Load Head

The Milwaukee M18 FUEL QUIK-LOK String Trimmer Attachment converts any compatible M18 FUEL power head into a fast, durable trimmer with a selectable 14" or 16" cutting swath.

This QUIK-LOK attachment snaps onto your M18 FUEL power head to deliver a professional-grade line trimmer designed for quick reloads, protected internals, and optimized gearing for consistent cutting performance. It’s built to pair with the M18 FUEL system so you get cordless run-time and torque control tuned specifically for string trimming tasks.

How fast and easy is line loading?

The attachment uses Milwaukee’s easy load trimmer head so you can spool line quickly without complicated winding patterns. Most users can reload up to 25 feet of line in under 30 seconds, reducing downtime on the job or around the yard.

• Easy load bump-feed head for fast spooling
• Supports up to 25 ft of trimmer line per reload
• Compatible line diameters: 0.080" and 0.095"

What cutting width and performance can I expect?

You can choose a narrower 14" swath to extend battery runtime or a wider 16" setting for greater clearing power when you need to cover more ground. RPM is tuned to the attachment’s gearing so the head runs between 0–4,900 and 0–6,200 RPM depending on power head output and load.

• Adjustable cutting swath: 14 in. for efficiency, 16 in. for capacity
• Optimized gearing matched to M18 FUEL RPM output
• Bump-feed action for controlled line advancement while trimming

Is the attachment durable and easy to maintain?

The QUIK-LOK drive shaft is protected to resist damage from drops and storage, extending service life compared with exposed designs. The unit’s simple mechanical layout makes routine maintenance and line replacement straightforward for homeowners and pros alike.

• Protected drive-shaft for improved resistance to impacts and debris
• Lightweight at approximately 3.75 lbs for reduced operator fatigue
• 36.25" overall length for balanced reach and control

Who is this for? The Milwaukee M18 FUEL QUIK-LOK String Trimmer Attachment is ideal for landscapers, contractors, and serious homeowners who already own or plan to invest in the M18 FUEL family. It’s a good fit when you want a quick-change attachment that offers professional features — fast line reloads, selectable cutting widths, and a sealed drive shaft for jobsite durability — without buying a separate dedicated trimmer. Pair it with a compatible M18 FUEL power head and Milwaukee batteries to tailor run-time and power to your workload.
