It’s time to put an end to compromises—no more trading size for productivity, weight for power, or ergonomics for efficiency. Now, you can have it all with just one tool.
Introducing GTG22 THOR – a high accessibility turbine grinder delivering market-leading power-to-weight ratio, superior ergonomic design, and proven durability with sustainability. Backed by over 25 years of expertise in developing turbine-driven tools, GTG22 THOR truly stands in a class of its own.
Power and Productivity
Excellent Ergonomics
Safety and Sustainability
Lightweight power
Don't let the size or weight of your tool stand in the way of completing tasks. With an impressive 2.3 kW more efficient turbine motor packed in only a 1.9 kg footprint, you're not just getting the best-in-market power-to-weight ratio - you're getting the job done faster than ever before.
More power in your hands, less weight on your shoulders
Concealed within GTG22 THOR's 1.9 kg is 2.3 kW max output turbine technology motor. With it, your job is not only made easier but altogether more comfortable.
With great power comes even greater gains
Outperforming standard similarly sized vane competitors, GTG22 THOR removes up to an impressive 67% more material or an additional 1.4 tonnes in one year of average grinding operations – 3h trigger time over 250 days.
Get more done in less time
Almost 150 fewer hours to remove one tonne of material as a conventional vane grinder motor
Ergonomics in every element
To consistently achieve superior grinding results, max power output is only half the equation—it demands exceptional ergonomics. Whether it’s the handle designs, the total height of the tool, air exhaust location, or vibration minimization, every feature is crucial in shaping the overall operator experience, and ultimately, the results.
Grind in any nook and cranny
No grind is out of reach for GTG22 THOR. With a total height of only 84 mm, it redefines compact power with the best-in-market power-to-weight ratio. This makes it possible to rough grind even the most cramped and narrow spaces with precision and ease.
Lower vibrations, lesser strain
Thanks to its compact size, shorter spindle, support handle with a new attachment bracket design, and state-of-the-art auto-balancer, vibrations are cut to less than 2.5 m/s2. Together, these stand-out features enable the operator to compensate for any imbalances, greatly reducing fatigue while protecting against vibration-related diseases such as white fingers.
No compromise on comfort
Beneath its extraordinary power lies an unparalleled operator experience. Every design feature is meticulously crafted to ensure operations are not just powerful, but also easier, faster, and more comfortable—ultimately elevating productivity, maneuverability, and safety.
The design features that make it all possible
Efficient and durable sustainability
Outperforming standard vane grinders, GTG22 THOR's turbine motor effortlessly removes material on even on the roughest surfaces, getting the same job done with 38% less compressed air. Achieving such an impressive rate of material removal at significantly lower air consumption per kW substantially reduces overall energy consumption.
Standards of safety and sustainability
Committed to sustainability and safety, GTG22 THOR adheres to Atlas Copco's Prohibited and Restricted lists, guaranteeing the use of safe chemicals and materials. What's more, the efficient turbine motor is oil-free, eliminating the necessity for lubricated air, significantly reducing oil usage for an eco-friendly and safe operational experience.
Guaranteeing a long time of satisfied grinding
Equipped with an extra durable angle gear and sealed angle heads, GTG22 THOR promises long service intervals and years of exceptional performance. To further extend tool life, simply perform a routine gearbox oil change every 500 hours of use, and service gears and spindle every 1 000 hours, or utilize available spare parts.
Efficient power, low energy consumption
Achieve the same material removal as standard vane competitors with 38% less air consumption
