Cobra GT3240VZ: 32cm (12.5") 40V Cordless Rotating Head Line Trimmer (Bare Tool)

The Cobra GT3240VZ brings ultimate cord-free freedom and UK-engineered practicality straight to your weekly garden routine, removing the classic frustrations of traditional grass strimmers. Purpose-built for discerning homeowners who want immaculate boundary borders, clean lawn edges, and tidy pathways, this 40V line trimmer eliminates the hassles of mixing two-stroke petrol, pull-start strain, or hauling dangerous extension leads across the damp turf. Highly maneuverable, lightweight, and balanced, it takes the physical exhaustion out of taming hard-to-reach garden growth.

Push-Button 45° Rotating Head & Customizable Cutting Track

  • Smart 45-Degree Articulating Trimmer Head: Sculpt pristine lawn edges and borders with a simple click. The trimmer head features a responsive push-button pivoting mechanism that swivels the cutting plane up to 45 degrees, allowing you to fluidly shift from horizontal grass trimming to vertical edge cutting in seconds.
  • Adjustable 28cm to 32cm Cutting Swath: Tailor your cutting footprint to match the task at hand. The high-efficiency trimmer head can be adjusted between a tight 28cm track for precision trimming around delicate flowerbeds and garden furniture, or opened up to a wide 32cm path for clearing open banks quickly.
  • Efficient 1.6mm Twisted Performance Line: Experience a cleaner, quieter slice. The pre-loaded 1.6mm twisted nylon cutting line is aerodynamically optimized to glide through thick grass blades with minimal wind drag, reducing overall motor decibels while conserving vital battery life.

Lightweight UK Ergonomics & Tool-Less Control Telemetry

  • Ultra-Lightweight 4kg Physical Frame: Prevent painful lower back and shoulder strain. Weighing a mere 4kg as a bare unit, the well-balanced straight shaft architecture ensures comfortable, low-fatigue operation over extended sweeping sessions across uneven ditches or allotments.
  • Adjustable D-Loop Auxiliary Handle: Personalize your steering stance. The heavy-duty front loop handle can be quickly slid along the straight shaft and locked to match the height and reach of any operator, maximizing stability and directional command.
  • Intuitive Single-Handed Trigger Array: Keep operations smooth and straightforward. The rear primary control grip features intuitively positioned safety switches and a variable-speed throttle placed perfectly under your thumb for hassle-free, immediate response.

The Cobra 40V Interchangeable Battery Platform

As a bare tool power unit, the GT3240VZ offers exceptional value by slotting straight into Cobra’s expanding 40V lithium-ion battery ecosystem, which spans three premium rotary lawn mowers and three handheld garden maintenance tools. Powered by high-grade Samsung battery cells, this efficient line trimmer can deliver an outstanding continuous runtime of up to 80 minutes on a single charge, refilling completely in just 90 minutes. Cobra proudly backs this dependable, emission-free residential grass trimmer with a comprehensive 2-year domestic manufacturer warranty.
