Hilti Nuron TE 4

Mar 10, 2023

The Hilti Nuron TE 4-22 compact rotary hammer caught our eye for a couple of reasons. First, this is the first compact rotary hammer we’ve seen from Hilti with both Active Torque Control (ATC) and Active Vibration Reduction (AVR). Both features play a more serious role in larger rotary hammers like the Hilti TE 30-22. However, we like seeing "trickle-down tech" that helps when doing smaller jobs as well. We wanted to know whether this new Hilti compact rotary hammer would prove a good value for Pros looking for a lighter-weight solution for drilling smaller diameter holes.

Hilti Nuron technology offers several performance and design advantages. Chief among them is the advanced battery technology that brings with it more power and runtime. With more reasonably-sized tools like this one, you really do get some impressive results.

Looking at Hilti's cordless TE 4 options, the previous model (TE 4-A22) matches the TE 4-22 on a number of specs. It lacks both ATC and AVR, however. And while the 22V Nuron platform moves away from 36V batteries, it doesn't seem to decrease power or runtime potential. Even the single-row B 22-85 Nuron 22V battery provides enough power to drive this tool.

Compared with the TE 4-A22, Hilti maintains the speed but tweaks the impact power to 1.7 ft-lbs. Couple that with the safety features we already mentioned, and you have a very capable, yet compact rotary hammer. With this increased power comes increased drilling up to 1-inch diameter holes. The older TE 4-A22 topped out at 23/32″. We do note that the corded TE 7 can tackle holes up to 1-3/32″—the same as the Hilti TE 6-22.

There are many benefits to Hilti's Nuron system, and you can read more about them in our deep dive here. For now, here's a quick list of what you can expect:

The Hilti TE 4-22 runs just $349 as a bare tool (or less than $20/month for Hilti Tools on Demand pricing). While that only saves you $20 off the price of a TE 6-22, it also gets you a more compact tool. When drilling overhead or on walls, that can make your day a lot better. Hilti also offers their 20-2-1 warranty program: a 20-year warranty, a 2-year free service, and a 1-day repair/maintenance turnaround.

Hilti offers its tools a la carte, so you can custom build your kit exactly how you want it. Here's a breakdown of the batteries and chargers:
