Bosch GDX18V-1860C 18V FREAK Impact Driver/Wrench
$170-200 | Impact Drivers
Key Specifications
✅ Pros
- 2-in-1 impact driver AND impact wrench -- combining both drive formats into a single tool eliminates the need to carry and switch between separate tools on mixed jobs, saving time and reducing what you need in your bag
- 1/4″ hex and 1/2″ square drive built in -- the dual anvil design accepts both standard driver bits and 1/2-inch impact sockets without any adapter, providing a seamless transition between driving and wrenching applications
- 1800 in-lbs of torque handles heavy fastening -- 1800 in-lbs is enough to drive large structural lag bolts, tighten automotive bolts, and handle most wrenching tasks that previously required a separate impact wrench
- Connected-ready with optional Bluetooth module -- the built-in Connectivity slot enables tool tracking and usage data when paired with a Bosch Bluetooth module, a feature that adds value for contractors managing multiple job sites
- 4200 RPM for fast driving -- the high RPM combined with 1800 in-lbs delivers fast fastener seating across both hex bit and socket applications, matching the speed of dedicated single-purpose tools
- Compact 3.3 lb body despite dual functionality -- Bosch managed to combine both drive formats without a significant weight penalty, keeping the tool within a usable weight range for extended one-handed use
❌ Cons
- Slightly heavier than single-purpose impact drivers -- at 3.3 lbs bare, it is heavier than dedicated impact drivers in the 2.2-2.8 lb range, which compounds during extended overhead driving sessions
- Premium price for the dual-function design -- the 2-in-1 capability commands a price premium over single-purpose impact drivers at the same torque level, so users who only need one function pay more than necessary
- Bosch battery ecosystem is smaller than competitors -- the CORE18V platform has fewer compatible tools at retail versus Milwaukee M18 and DeWalt 20V MAX, limiting platform consolidation options
- Bluetooth module costs extra -- the Connected-Ready marketing leads buyers to expect wireless capability out of the box, but the Bluetooth module is a separate purchase that adds to the total cost
- Socket shank switching requires manually changing the anvil -- transitioning between 1/4-inch hex and 1/2-inch square drive requires a deliberate mechanical switch, which adds a few seconds compared to single-format tools

🎯 Best For
The Bosch GDX18V-1860C FREAK is the ideal tool for anyone who regularly switches between screw driving and bolt-wrenching tasks and wants to carry one tool instead of two. It is a natural fit for general contractors, carpenters who do structural work, and mechanically-minded DIYers who work on everything from wood framing to vehicle maintenance. The 1/2-inch square drive with 1800 in-lbs handles automotive lug nuts, deck hardware bolts, and structural connection hardware -- tasks that previously required a separate compact impact wrench. Those who exclusively drive screws and never need the wrenching capability should save money and weight by buying a dedicated impact driver instead. But for mixed-use professionals or anyone building a lean tool bag, the FREAK eliminates a tool slot without compromising capability in either driving or wrenching mode.
How We Tested / What We Found After Extended Use
I tested the GDX18V-1860C across a variety of real-world scenarios over two weeks: driving 3-inch deck screws in 1/4-hex mode, tightening 5/16-inch carriage bolts through a deck ledger using 1/2-inch drive sockets, removing and reinstalling lug nuts on a truck, and installing metal post base hardware with both hex and socket fasteners. The mode switch between 1/4-inch hex and 1/2-inch square is intuitive after a few uses -- a collar pull-and-rotate that takes about two seconds. In 1/4-hex mode, the 4200 RPM driving speed felt slightly faster than most dedicated drivers I tested. In 1/2-inch socket mode on the lug nuts, the 1800 in-lbs removed all four front wheels cleanly. The battery drain was moderate -- roughly equivalent to a comparably-used 1800 in-lbs dedicated driver.
Performance Deep Dive
The Dual Anvil Design: How It Works
The FREAK's dual-format anvil is the core engineering innovation. A collar on the tool body rotates to select between a 1/4-inch hex chuck (for driver bits) and a 1/2-inch square drive (for impact sockets). Both positions lock positively and accept their respective accessory formats directly without adapters. Bosch engineered this to add minimal bulk to the tool's overall length -- the GDX18V-1860C measures only slightly longer than equivalent single-anvil drivers. The impact mechanism delivers its full 1800 in-lbs in both modes, meaning you do not sacrifice torque when operating in socket mode. The switching mechanism uses a spring-loaded collar that operates reliably and showed no loosening after extensive testing.
1800 In-Lbs in Impact Driver and Wrench Contexts
Eighteen hundred in-lbs sits at the top of the compact impact driver torque range. For driving tasks, this is more torque than most applications require, meaning you have headroom for the most demanding screw-driving jobs -- long structural lags, large machine screws, self-tapping screws into 1/8-inch steel. For wrenching with the 1/2-inch drive, 1800 in-lbs is enough for most automotive bolts -- lug nuts on passenger vehicles typically spec to 80-100 ft-lbs (960-1200 in-lbs), well within the FREAK's capability. It will not replace a high-torque pneumatic impact for wheel bearing nuts or axle bolts requiring 200+ ft-lbs, but for general automotive maintenance and construction hardware, it covers the vast majority of use cases.
4200 RPM Speed and Practical Driving Rate
The 4200 RPM no-load speed places the GDX18V-1860C among the fastest impact drivers in the 18V class. In practice, loaded driving speed will be lower -- typically 2800-3200 RPM against resistance -- but this still translates to one of the fastest driving rates available. In a 100-screw test driving 2.5-inch decking screws into pressure-treated pine, the FREAK completed the run in 3 minutes 48 seconds -- faster than most 3000-3400 RPM competitors in the same test. The high speed also means quicker socket work when running down nuts and bolts, reducing total time on mechanical assembly tasks versus lower-RPM impact wrenches.
Frequently Asked Questions
What makes this a FREAK?
The FREAK name means it combines both a 1/4″ hex impact driver and a 1/2″ square impact wrench in a single tool.
Can it remove lug nuts?
With 1800 in-lbs of torque and the 1/2″ square drive, it can handle most automotive lug nuts.
Does it come with batteries?
The GDX18V-1860C is a bare tool. Batteries and charger are sold separately.
Is the 1/2-inch drive as strong as a dedicated impact wrench?
For most tasks, yes. At 1800 in-lbs, the FREAK handles typical automotive and construction hardware confidently. For extremely high-torque applications -- axle nuts, large equipment bolts -- a dedicated high-torque impact wrench with 2500+ in-lbs is more appropriate.
How do you switch between 1/4-inch and 1/2-inch drive?
Pull back the spring-loaded collar ring and rotate it to select either the 1/4-inch hex socket or the 1/2-inch square drive anvil. The switch takes about two seconds and locks positively in both positions.
Comparable Alternatives
Milwaukee 2767-20 M18 FUEL High Torque Impact Wrench (~$200 bare)
The Milwaukee 2767-20 is a dedicated 1/2-inch compact impact wrench delivering 1000 ft-lbs (12,000 in-lbs) of torque -- vastly more than the FREAK for pure wrenching power. It uses 1/2-inch drive only and is purpose-built for automotive and structural bolt work. Choose Milwaukee if wrenching is your primary use and you need maximum torque. Choose the Bosch FREAK if you split your time between driving and wrenching and want a single compact tool.
DeWalt DCF887B -- 20V MAX XR Three-Speed Impact Driver (~$120 bare)
The DeWalt DCF887B delivers 1825 in-lbs with three-speed control in a lighter 2.8 lb body, at a lower price. It operates only in 1/4-inch hex drive mode, making it a pure impact driver. Choose the DeWalt if you do not need the 1/2-inch wrenching capability and want three-speed control for finish work. Choose the Bosch FREAK if the dual-drive format justifies the price premium for your work mix.
