Hilti Impact Drivers
Hilti builds impact drivers for contractors who buy tools by the hundred and want service guaranteed. Here is what the Nuron models offer, how Hilti's service and fleet model works, and whether it makes sense for anyone else.

The Hilti impact driver most buyers look at is the Nuron SID 6-22, a 3-gear 22V driver rated at up to 300 Nm (about 2,655 in-lbs) that weighs about 2.2 lb as a tool body. The single-speed SID 4-22 is the lighter, simpler option. What sets Hilti apart is not the driver but the service: a 20-year defect warranty, two years of no-cost repairs and fleet management. For homeowners and small shops, the price and limited tool access usually outweigh those benefits.

Hilti Nuron impact driver lineup
Hilti's current cordless impact drivers run on the Nuron 22V battery platform. There are two main models. Hilti publishes torque in newton-meters (Nm); we convert to in-lbs (1 Nm is about 8.85 in-lbs). Hilti, like every brand, uses its own test method, so cross-brand comparisons are rough at best.
| Spec | SID 6-22 | SID 4-22 |
|---|---|---|
| Gears | 3 | 1 |
| Max torque by gear | 150 / 300 / 300 Nm | 186 Nm |
| Approx. in-lbs | 1,327 / 2,655 / 2,655 | 1,646 |
| Tool body weight | 0.994 kg (about 2.2 lb) | 0.852 kg (about 1.9 lb) |
| Position | Heavy-duty, all-round | Compact, economical alternative |
Hilti's own pages warn that these tools should not be used where an exact torque is specified. That applies to every impact driver: finish lug nuts, anchors and structural bolts with a spec using a torque wrench.
Best Hilti impact driver: SID 6-22
Hilti Nuron SID 6-22 Cordless Impact Driver
Best for: commercial contractors, MEP trades and crews already on Nuron.
- Torque
- up to 300 Nm (about 2,655 in-lbs)
- Gears
- 3
- Weight
- about 2.2 lb tool body
- Platform
- Nuron 22V
The SID 6-22 is Hilti's full-size driver. Gear 1 limits torque for small screws and soft materials; gears 2 and 3 deliver full output for lags, structural screws and concrete screws. It is built for jobsite abuse and backed by Hilti's service network.
Strengths
- Very high rated torque for a 1/4-inch driver
- Built for heavy commercial use
- Backed by Hilti's warranty and fast repair service
Weaknesses
- Costs considerably more than comparable pro drivers
- Fewer modes than Milwaukee's or Makita's mode systems
- Limited retail availability; mostly bought direct
Hilti Nuron SID 4-22 Compact Impact Driver
Best for: installers and finish trades who want a lighter Hilti driver.
- Torque
- 186 Nm (about 1,646 in-lbs)
- Gears
- 1
- Weight
- about 1.9 lb tool body
Hilti positions the SID 4-22 as the economical alternative. It handles most screws and smaller lags without the weight of the 6-22.
Strengths
- Lighter and simpler
- Same batteries and service as the 6-22
Weaknesses
- Single gear means less control on small screws
- Still priced above mainstream compact drivers
Using the SID 6-22 gears on the job
The SID 6-22's three gears are simpler than the app-tuned modes some rivals offer, but they cover most commercial work. Gear 1 caps torque at about half of full output, which protects small screws. Gears 2 and 3 share the same maximum torque, so the difference between them is mainly speed. Here is a practical starting point:
| Gear | Max torque | Typical jobs |
|---|---|---|
| 1 | 150 Nm | Cabinet and trim screws, drywall to wood, small sheet-metal screws, fixtures into soft material |
| 2 | 300 Nm | Construction screws, concrete screws, unistrut and hanger hardware, medium lags |
| 3 | 300 Nm | Long structural screws and large lags where speed matters |
Use impact-rated bits and sockets, since standard bits shatter at this output. Drill pilot holes for lags larger than 1/4 inch. If you mostly run nuts and bolts rather than screws, read impact driver vs impact wrench, since a wrench may suit the work better.
How Hilti's service model works
Hilti sells a service promise as much as a tool. Its US tool warranty page describes three layers. Exact terms depend on the tool, so confirm them with Hilti for the model you buy.
- 20-year defect warranty: Hilti repairs or replaces parts that fail from defects in materials or workmanship.
- No-cost repair period: for the first two years, repairs are free even for normal wear and tear, excluding abuse or use against the manual.
- Repair cost cap: after the no-cost period, Hilti's published terms cap repair charges at a percentage of the tool's list price.
Hilti also runs its own repair centers with pickup and fast turnaround. For a contractor, that predictability is the real product.
Fleet management and the Nuron platform
Large customers often do not buy Hilti tools at all. Under fleet management, a company pays a monthly fee per tool. Hilti covers service and repairs, replaces tools when needed and handles inventory tracking. Contracts typically run several years. The appeal is fixed costs and less time spent managing tools, chasing repairs and replacing stolen kit.
Nuron is built for that model. Nuron batteries store usage and health data that Hilti and fleet customers can use to see which packs and tools are in use and when they need service. For a company with hundreds of tools across many sites, that visibility saves money. For one person with two batteries, it adds little.
| Factor | Buy outright | Fleet management |
|---|---|---|
| Upfront cost | Full tool price | Monthly fee per tool |
| Repairs | Warranty and no-cost period | Included |
| Tool tracking | Optional | Included |
| Best for | Small firms, individual pros | Mid-size and large contractors |
The pricing reality
Hilti tools cost more than Milwaukee, DeWalt or Makita equivalents, and discounts are rarer. Prices are often tied to account agreements, so the list price you see online may not be what a large contractor pays. Batteries are also expensive. Factor in at least two Nuron packs and a charger if you are starting from zero, because a bare Hilti driver is only useful once you own the battery system. Hilti does sell kits, but check what is included before comparing prices. For an individual buyer, Hilti only makes sense if you value the service terms enough to pay the premium, or if your employer runs Nuron already.
The alternatives are strong. A Milwaukee impact driver on M18 offers comparable performance, a larger tool range, more modes and easy availability. Our guide on impact driver torque explains why the bigger Nm figure on a Hilti spec sheet does not settle the comparison.
Should you buy a Hilti impact driver?
- Large commercial contractors: yes, especially through fleet management. The service model is built for you.
- Trades whose employer runs Nuron: stay on Nuron so batteries are shared.
- Concrete and anchor-heavy work: Hilti's anchoring and drilling range pairs naturally with its drivers. For driving concrete screws, see how to install Tapcon screws.
- Small shops and individuals: usually no. Pick a mainstream platform using our guide to choosing a cordless tool platform.
- Homeowners: no. The premium buys service you will not use.

Verdict
The Hilti SID 6-22 is a tough, high-torque driver, and the SID 4-22 is a capable lighter option. Hilti's real advantage is its 20-year warranty, no-cost repair period and fleet management, which large contractors value highly. The weaknesses are price, limited retail access and fewer modes than rivals. Outside large firms, a mainstream pro platform gives similar results for less.
Frequently asked questions
Are Hilti impact drivers worth the money?
For large contractors who track and service many tools, often yes, because downtime and repair costs matter more than purchase price. For a homeowner or small shop, a Milwaukee, DeWalt or Makita driver delivers similar results at a lower cost and is easier to buy and repair locally.
Where can you buy Hilti tools?
Hilti sells mainly direct through hilti.com, Hilti stores and account managers. Some Hilti tools also appear at The Home Depot. Availability on Amazon is limited and inconsistent, and third-party sellers may not provide Hilti's full service terms.
Do Hilti batteries fit other brands?
No. Hilti Nuron 22V batteries fit only Hilti Nuron tools. Older Hilti 22V packs and Nuron packs are separate generations, so check compatibility before mixing them on a jobsite.
What is Hilti fleet management?
It is a subscription where a company pays a monthly fee per tool instead of buying outright. Hilti covers service and repairs, swaps tools when needed and provides inventory tracking. It suits companies that want predictable costs and less tool administration.
Is Hilti torque comparable to Milwaukee or DeWalt?
Not directly. Hilti publishes torque in newton-meters using its own method, and every brand tests differently. The SID 6-22's rating converts to about 2,655 in-lbs, but that number does not prove it drives faster than a 2,000 in-lb Milwaukee in practice.
