Hilti Nuron Cordless 6-Inch Angle Grinder AG 6D-22 Performance
Hilti impressed us by powering a 6-inch grinder with a brushless motor and a single 22-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 22V power source, you get that performance with less weight than some of the other options.
The cutting performance is excellent, though we can tell that some of the higher voltage systems have more torque in reserve. Even so, it takes some effort to bog down Hilti’s brushless motor, and the majority of your grinding, cutting, and polishing tasks are just as easy and fast as you can work with other cordless options.
Hilti Nuron Cordless 6-Inch Angle Grinder Design
360° Active Torque Control
Hilti’s 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 full working area and if it quickly leaves that zone in any direction, the motor shuts off.
SensTech
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 Nuron Benefits
One of the Nuron system’s benefits improved the overall performance of each tool with a better pack design allowing for more efficient energy flow. It also shifts away from a separate 36V system for higher-draw tools and goes with a 2 x 22V design so the same batteries support both performance tiers.
New technology is also built into the system. As you use a Nuron tool, diagnostic and use information stores on the battery pack and can be uploaded when you place it on the charger. That might not be a big deal for individual tradesmen, but it’s a big time-saver for crib managers working with maintenance schedules and asset management.
Size and Weight
Without a battery, the grinder only weighs 4.6 pounds. With the B 22-170 battery (2P pack, 8.0Ah), the total weight is 7.5 pounds.
The tool is also just 11.8 inches long and your battery selection will determine the total length. Regardless, it’s more compact than DeWalt’s FlexVolt grinder. It’s close as a bare tool but adds more length and weight with its battery.
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
