King Series GK-700 Grinder
It isn’t just grinding — it’s living the grind. The new era of concrete grinding and polishing starts here.
Pushing The Boundaries
It goes beyond just grinding and polishing concrete. For some it’s an art, for others it’s a vehicle that builds a dream lifestyle. Every craftsman needs a machine that delivers, so they can.
The King Series changes everything. It marks the beginning of a new era — one where you have the power to bring your vision to life. Every component of the King Series is designed to excel and endure, to empower your mark on the trade.
With the King Series it isn’t just grinding — it’s living the grind. So, take the reins and push the boundaries of your grind, because the possibilities are endless with the WORX+ King Series Grinders.
Beyond Concrete
Big Power, But Better
A 22kW permanent magnet motor crowns the King Series, offering intelligent control and integrated sensors that deliver real-time feedback to frequency inverters. This lets you fine-tune operations and maximise performance at every stage of your process.
More Efficient, More Durable
The King Series has heavy-duty parts for heavy-duty jobs, made possible by the permanent magnet motor’s reduction in weight in comparison to standard induction electric motors — giving the flexibility for added strength and rigidity in other components such as its heavy-duty axle and bearings.

Wheel Drives, Reimagined
Joystick Precision
Customise the King Series’ responsiveness to joystick movements for precise control.
Reliable Wheel Locks
Move your grinder easily when it’s turned off with the King Series’ unique locking mechanism.
Easy Transportation
The tip-back system with built-in jockey wheel makes moving the grinder simple — and the wheel neatly retracts when not in use.
Real-Time Diagnostics, More Time Grinding
With the King Series you’ll have unprecedented access to your grinder’s live performance and GPS location via WORX+’s unique online portal — and catch problems before they arise.
That means easy real-time troubleshooting, performance tracking, and added security.
Geometry That Conquers Every Job
Made for Tight Jobs
Specially designed for optimal handling, so you can enjoy unprecedented manoeuvrability in tight working environments.
Classy Transport
It’s built in and it’s easy. The King Series is ready for transport with its fold-out jockey wheel and fit-for-purpose chassis geometry.
Easy Charging
Trickle charge the on-board battery from mains power in storage — and plug your phone into the built-in USB port while on the grind.
Radio Control Revitalised
With cutting-edge tech infrastructure, the radio control system guarantees reliable connectivity — so you can keep grinding, and grinding, and grinding. With a few touches you have fine control over all your vital inputs; with one look you can see key productivity information and the grinder’s rotational disc and planetary head direction.
Ultimate Autopilot
Autopilot mode is a game changer. Line the King Series RC up once and watch as it automatically U-turns and lane merges — technology expected of static high-precision manufacturing, now available for mobile surface manufacturing. The advanced control algorithm doesn’t just move forwards: it also runs in reverse to remove turn requirements entirely.
Tilt-Back System
The King Series’ Split-Chassis Tip-Back System will revolutionise your workflow. Changing tooling is no longer a hassle — this system lets you lift the grinding head easily.
Fine-tune tooling pressure with dynamic adjustments and get complete control, without the limitations of fixed weight settings.
