Hilti Nuron Cordless 6-Inch Angle Grinder AG 6D-22

Hilti Nuron Cordless 6-inch Angle Grinder AG 6D-22

Hilti Nuron Cordless Angle Grinder Line Anchored By Intelligent 6-Inch Model

With its 6-cell system and upgraded tech, Hilti Nuron is redefining what you can expect from its 21.6-volt system. Anchoring the grinder line, the Hilti Nuron AG 6D-22 cordless 6-inch angle grinder opened our eyes.

Hilti Nuron Cordless 6-Inch Angle Grinder AG 6D-22 | The Big Deal


Hilti impressed us by powering a 6-inch grinder with a brushless motor and 21.6-volt battery. While the 6-cell system does have an extra cell per row compared to the 5-cell 18V/20V Max packs, most brands moving into the medium angle grinder class are doing it with 36V/40V Max or 54V/60V Max voltage levels.

For cutting and grinding, you have up to 8500 RPM at your disposal. Because of the single 21.6V power source, you get that performance with less weight than with Hilti’s 36V system.

Surface Grinding


The performance is impressive, but the new intelligence redefines angle grinder safety completely. It starts with 360° Active Torque Control. Effectively, the tool now senses your working area and if it quickly leaves that zone in any direction, the motor shuts off.

Another innovative element is SensTech. It’s a sensor in the handle that can tell when you have control of the tool. If you drop it, set it down, or take your hand off for any other reason, the motor shuts down. Thanks to this technology, you have the always-on convenience of a slide switch with the deadman function of a paddle switch—it’s the best of both worlds!

Additional Highlights

  • Slim, compact design
  • 2-position side handle
  • Electronic overheating and overload protection
  • Wheel brake
  • Compatible with DG-EX 125/5 and DC-EX 125/5 M dust hoods
