Bosch Impact Drivers
Bosch makes excellent impact drivers that get far less attention than the big three. Here is what the 12V and 18V lineups offer, which models matter and who should buy into the platform.

The Bosch impact driver most people should look at is the 18V GDR18V-1860C: 1,860 in-lbs, up to 4,100 IPM and three speeds in a short brushless body. If you also need a 1/2-inch square drive, the GDX18V-1860C Freak does both jobs. For tight spaces and light fastening, the 12V PS42 (975 in-lbs) is a capable compact. Bosch's weakness is not the tools but the platform: a smaller cordless range and fewer deals than Milwaukee, DeWalt or Makita.

Bosch impact driver lineup at a glance
Bosch sells impact drivers on two US platforms: 18V for full-size work and 12V Max for compact, light-duty work. The model numbers look cryptic, but they encode the useful information. GDR means a 1/4-inch hex impact driver, GDX means Bosch's two-in-one Freak, and the number after the voltage is the rated torque in in-lbs. Specs below come from Bosch's US product pages and are rounded the way Bosch publishes them.
| Model | Platform | Rated torque | Impact rate | Notes |
|---|---|---|---|---|
| GDR18V-1860C | 18V | 1,860 in-lbs | up to 4,100 IPM | 3 speeds (0-1,100/2,300/3,400 RPM), 4.9 in long, connected-ready |
| GDX18V-1860C (Freak) | 18V | 1,860 in-lbs | up to 4,100 IPM | 1/4-in hex plus 1/2-in square drive, auto bolt release |
| GDR18V-1800 | 18V | 1,800 in-lbs | up to 4,000 IPM | Simpler brushless model, often sold in starter kits |
| PS42 | 12V Max | 975 in-lbs | 0-2,700/3,100 IPM | 2 speeds (0-1,200/2,600 RPM), 1.6 lb bare |
Bosch rates torque with its own method, like every brand. Use the numbers to place a tool in its class, not to declare a winner over a Milwaukee or DeWalt with a slightly lower figure. Kit suffixes change often (CN for bare tool, B15 or B25 for kits with batteries), so check the current listing for what is in the box.
The Bosch 18V impact driver to buy: GDR18V-1860C
For most buyers the GDR18V-1860C is the pick. It sits in the same class as the DeWalt DCF887 and Makita XDT16, with three speed settings for control on small screws and full output for lags and structural screws. At 4.9 inches long it is compact for an 18V tool, which helps between studs and joists.
Bosch 18V Brushless Connected-Ready Impact Driver (GDR18V-1860C)
Best for: general construction, decking, cabinet install and anyone already on Bosch 18V.
- Torque
- 1,860 in-lbs
- Speed
- 0-1,100/2,300/3,400 RPM
- Impacts
- up to 4,100 IPM
- Length
- 4.9 in
It has the torque class of the leading 18V drivers, a short head and a mode system you can tune further with the optional connectivity module. It is a balanced, professional tool rather than a spec-sheet chaser.
Strengths
- Full 18V output in a short body
- Three speeds cover trim screws through lag bolts
- Bluetooth customization is optional, not required
Weaknesses
- Fewer modes than Milwaukee's 4-Mode Drive Control without the app
- Smaller tool range than the market leaders
- Discounts and kit bundles are less common
The Bosch Freak: impact driver and wrench in one
The GDX18V-1860C is the model Bosch is known for. Its chuck takes 1/4-inch hex bits like any impact driver, and the outside of the same chuck works as a 1/2-inch square drive for sockets. That means one tool can drive deck screws in the morning and run carriage-bolt nuts in the afternoon without a hex-to-square adapter.
Bosch 18V Brushless Freak Impact Driver (GDX18V-1860C)
Best for: tradespeople and DIYers who drive screws and run small nuts and bolts.
- Torque
- 1,860 in-lbs
- Impacts
- up to 4,100 IPM
- Drive
- 1/4-in hex and 1/2-in square
It replaces a socket adapter and, for light bolting, a small impact wrench. The auto bolt release mode slows the tool as a nut comes free so it does not spin off and drop.
Strengths
- No adapter wobble with sockets
- Same torque class as the GDR
- Useful auto bolt release
Weaknesses
- Bulkier nose than a plain hex driver
- Still an impact driver: not a substitute for a mid-torque wrench on lug nuts
- Costs more than the GDR
If heavy bolting is a regular job, read impact driver vs impact wrench before assuming the Freak covers it. Any critical fastener with a torque spec, such as lug nuts, must be finished with a torque wrench.
Bosch 12V impact driver: the PS42
The PS42 is Bosch's 12V Max brushless impact driver. With 975 in-lbs and two speeds, it handles cabinet screws, electrical boxes, HVAC sheet-metal screws and 2 to 2-1/2-inch construction screws. It is not meant for lags or long structural screws. Its 1.6 lb bare weight makes it a good overhead and in-cabinet tool.
Strengths
- Light and compact
- Two speeds give control on small fasteners
- Shares batteries with Bosch's 12V drills and saws
Weaknesses
- Torque well below Milwaukee's M12 FUEL 3453 (1,500 in-lbs, measured differently)
- Older design; check whether a newer 12V model is listed
- 12V range is narrower than M12

Batteries, modes and connectivity
Batteries
Bosch's US 18V tools use slide-style packs. The CORE18V packs are the higher-output line and pair well with the 1860 drivers. A 2.0 to 4.0 Ah pack keeps an impact driver light; bigger packs add runtime for decking. For background on capacity and weight, see our impact driver battery guide. Bosch's 12V Max packs are a separate system and do not fit 18V tools.
Modes and the C suffix
The 1860 drivers have three speed settings plus preset modes. Connected-ready (C) models accept an optional Bluetooth module. With it, you can set custom speed and torque profiles in Bosch's app, which is useful for repetitive work like sheet-metal screws. Without it, the tool runs normally.
Warranty
Bosch's 18V product pages list a 5-year limited warranty on the tool and charger and 3 years on the battery for 18V products since mid-2023. Check the current terms on boschtools.com before you buy, since coverage differs by product family.
How Bosch compares with other brands
| Factor | Bosch 18V | Milwaukee, DeWalt, Makita |
|---|---|---|
| Top impact driver torque | 1,860 in-lbs | 1,600 to 2,000 in-lbs |
| Tool range | Solid for trades, narrower overall | Hundreds of tools each |
| Where to buy | Lowe's, Home Depot, online, tool dealers | Everywhere |
| Deals and kit bundles | Occasional | Frequent |
| Standout feature | Freak two-in-one chuck | Varies by brand |
The tool itself is not the reason to choose or skip Bosch. The platform is. If you already own Bosch 18V drills or saws, the 1860 drivers are an easy yes. If you are starting fresh, weigh the full range of tools you will want over the next few years. Our guide to choosing a cordless tool platform walks through that decision, and the Makita impact driver guide covers another brand known for refinement over raw numbers.
Who should buy a Bosch impact driver?
- Already on Bosch 18V: buy the GDR18V-1860C bare, or the Freak if you run sockets often.
- Electricians and installers: the Freak saves an adapter, and the PS42 suits overhead and in-box work.
- New buyers who want the widest tool choice: look at the larger platforms first, then compare.
- Homeowners on a tight budget: Bosch is usually not the cheapest way in. Wait for a kit deal or compare value brands.
Wear eye protection when driving, and hearing protection for long sessions. Every impact driver is loud under load.
Verdict
Bosch makes impact drivers that stand alongside the big names, and the Freak is genuinely unique. Buy the GDR18V-1860C or GDX18V-1860C if you are on Bosch 18V or like the two-in-one idea. The weaknesses are a smaller tool range and fewer discounts, so new buyers should choose the platform first and the driver second.
Frequently asked questions
Are Bosch impact drivers good?
Yes. Bosch's brushless 18V drivers publish competitive specs, run cool and are well built. Owner feedback is generally positive on durability. The main trade-offs are a smaller tool range than the market leaders and less frequent discounting at the big-box stores.
Who makes Bosch power tools?
Bosch power tools are made by Robert Bosch GmbH, the German company. In the US, Bosch professional tools are sold under the Bosch blue line, and Bosch also owns the Dremel brand. The US 18V and 12V Max tools are designed for the North American market.
Do Bosch 18V batteries fit all Bosch 18V tools?
Bosch's current US 18V slide-style batteries, including CORE18V packs, are designed to work across its 18V tool range. Very old Bosch packs with a different shape do not fit. Check the battery model against the tool's compatibility list before buying.
What does the C mean in Bosch model numbers?
A C suffix (as in GDR18V-1860C) marks a connected-ready tool. It accepts an optional Bluetooth module that lets you adjust settings and track the tool through Bosch's app. The tool works normally without the module.
Is the Bosch Freak an impact driver or an impact wrench?
Both. The GDX18V-1860C has a socket-ready chuck that holds 1/4-inch hex bits and also works as a 1/2-inch square drive. It is a good fit if you drive screws and also run small nuts and bolts.
