Intro
When a fastener has been exposed to decades of heat, corrosion, and over-torquing, no amount of leverage from a breaker bar will budge it. On heavy commercial vehicles, agricultural machinery, and industrial plant, the bolts holding suspension arms and hub assemblies together can require over 1,500 Newton metres of force to break free — well beyond what a standard impact wrench can deliver. This is the domain of the high-torque cordless impact wrench: a tool purpose-built to generate immense, sustained hammering force for fasteners that have welded themselves in place over years of service. A good high-torque wrench on an 18-volt brushless platform combines that raw breaking force with enough battery capacity to work a full shift — without the air hose, compressor, and ear-splitting noise of a pneumatic equivalent. For the heavy-vehicle technician, agricultural engineer, or industrial maintenance crew, a capable high-torque cordless impact wrench is not a luxury — it determines whether a job takes five minutes or an entire afternoon.
Generalities
Shopping for a high-torque cordless impact wrench means looking past the marketing numbers to what actually matters on the job. Torque rating is the starting point: for heavy commercial and industrial work, you want at least 1,000 Nm of nut-busting torque, and the best tools in this class push past 1,600 Nm. But raw torque is useless without control — look for multiple speed and torque settings plus a variable-speed trigger, because a tool that only delivers maximum force will snap smaller fasteners and round off stubborn ones. The battery system is critical: high-torque work drains batteries fast, so a kit with at least two high-capacity 5.0 Ah packs and a fast charger means you keep working while one pack charges. A brushless motor is essential — it generates less heat, lasts longer, and delivers more of the battery's energy to the anvil. Finally, a proper ToughSystem or similar modular case protects a £400+ investment and keeps everything organised and stackable.
This review examines the FACOM CL3.CH18SP2, a French-engineered ½ inch high-torque cordless impact wrench that delivers a massive 1,625 Nm of torque. We will cover its carbon-free brushless motor, 3-speed control, dual 5.0 Ah battery kit, ToughSystem case, and what it is like to use on the kind of heavy-duty fasteners that defeat lesser tools. We will also give an honest breakdown of pros, cons, and the professional environments where this premium French tool earns its keep.
Description
The FACOM CL3.CH18SP2 is a French-designed ½ inch (12.7 mm) cordless high-torque impact wrench that sits at the top of FACOM's 18-volt cordless range. Its carbon-free brushless motor generates a staggering 1,625 Newton metres of maximum torque — enough to break free wheel nuts on heavy goods vehicles, seized suspension bolts on agricultural tractors, and rusted subframe fasteners on industrial plant that have not been disturbed in decades. The kit is genuinely complete: two 5.0 Ah lithium-ion batteries, a fast charger, and a DeWalt ToughSystem modular storage case with custom foam insert. The entire kit weighs approximately 8.7 kg in the case. This is a professional-grade tool manufactured to FACOM's exacting French standards, backed by a 2-year manufacturer's warranty.
Control is where the CL3.CH18SP2 separates itself from older high-torque tools that offered only one speed: full power, all the time. FACOM have equipped it with three distinct speed and torque settings plus a fully variable trigger with dimmer-style progressive control. Setting 1 delivers controlled power for assembly and smaller fasteners; setting 2 provides mid-range torque for standard automotive work; setting 3 unlocks the full 1,625 Nm for the biggest, most stubborn bolts. The variable trigger lets you feather power within each setting, so you can start a bolt gently to avoid cross-threading before ramping up. An integrated LED illuminates the work area, and the body is made from chemical-resistant composite that stands up to the oils, solvents, and degreasers that are a fact of life in any heavy workshop.
On the workshop floor, the CL3.CH18SP2 justifies its premium positioning within the first few fasteners. A seized wheel nut on a delivery lorry — torqued to 600 Nm and driven through three winters of road salt — yields in under three seconds of sustained hammering. The brushless motor does not fade or overheat even during back-to-back use on a full set of twenty wheel nuts. The 5.0 Ah batteries deliver enough runtime for heavy workshop use without constant swapping, and the fast charger tops up a depleted pack in well under an hour. The ToughSystem case clips into DeWalt's modular storage system, so it stacks neatly with other ToughSystem boxes on a workshop shelf or in a service van.
FACOM's heritage is worth noting. The brand has been manufacturing professional tools in France since 1918, with a reputation built on supplying the French automotive, aviation, and aerospace industries. Their tools carry a lifetime guarantee on non-technical products; the CL3.CH18SP2 falls under the 2-year warranty as a technical product, but the century-long commitment to quality engineering is evident. The chemical-resistant composite body shrugs off brake cleaner, diesel, and hydraulic fluid — substances that would degrade the rubber overmould on lesser tools within months. The ½ inch square anvil accepts standard impact sockets, and the retaining ring holds sockets securely without a detent pin.
With 4.3 out of 5 stars from 17 reviews and a rank of #161 in Impact Wrenches, the CL3.CH18SP2 has limited but positive user feedback — typical for a specialist professional tool sold through trade channels. At £420 for the complete kit with two 5.0 Ah batteries, charger, and ToughSystem case, it competes at the premium end against Milwaukee Fuel High Torque and DeWalt XR. The value equation is strong for professionals who need extreme torque, brushless reliability, and a ready-to-work kit — particularly where FACOM's chemical-resistant build and French engineering heritage matter more than brand familiarity.
Pros and cons
Pros
- Monstrous 1,625 Nm of nut-busting torque — frees seized wheel nuts, suspension bolts, and rusted industrial fasteners that lesser impact wrenches cannot touch
- Complete ready-to-work kit with two 5.0 Ah batteries, fast charger, and DeWalt ToughSystem case — no additional purchases needed, and the modular case stacks with other ToughSystem storage
- Three speed settings plus fully variable dimmer-style trigger — from delicate assembly torque to full 1,625 Nm breaking force, all controllable with one finger
- Carbon-free brushless motor generates less heat, lasts longer, and delivers more torque per watt — essential at this power level where a brushed motor would overheat during sustained heavy use
- Chemical-resistant composite body withstands brake cleaner, diesel, hydraulic fluid, and degreasers — chemicals that eat through rubberised grips on standard workshop tools
- French engineering from a brand founded in 1918 with a century of aerospace, automotive, and industrial tool heritage — the build quality reflects that pedigree
- Integrated LED and ½ inch square drive with secure socket retention — ready for standard impact sockets and visible in the shadowed underside of a heavy vehicle
Cons
- At £420 it is a serious investment — firmly in the premium bracket, and only justifiable for professionals who genuinely need 1,600+ Nm of torque on a regular basis
- Kit weight of 8.7 kg in the case makes it heavy to carry between workshop bays — the tool itself is manageable, but the full kit is not something you want to lug across a large site daily
- Only 17 reviews at 4.3 stars — the limited feedback pool makes long-term reliability harder to assess than mass-market competitors with hundreds of reviews
- FACOM's 18V battery platform is smaller than Milwaukee M18 or DeWalt XR — if you want to share batteries across a wider range of cordless tools, the ecosystem is more limited
- 1,625 Nm is overkill for standard automotive work — for a typical passenger-car mechanic, a medium-torque 600 to 800 Nm wrench would be lighter, cheaper, and more than adequate
Use cases
A French-engineered high-torque ½ inch cordless impact wrench delivering 1,625 Nm for heavy commercial vehicle technicians, agricultural engineers, and industrial maintenance crews who need extreme breaking force and a complete kit with dual batteries, charger, and ToughSystem case.
Heavy Commercial Vehicle Maintenance
Lorry wheel nuts torqued to 600+ Nm, seized suspension arm bolts on buses, and rusted chassis fasteners on delivery fleets all yield to 1,625 Nm of breaking torque. The two 5.0 Ah batteries and fast charger keep pace with a full workshop shift without waiting for air-compressor recovery time.
Agricultural Machinery and Tractor Repair
Tractors, combines, and balers are held together by large fasteners exposed to mud, manure, and years of neglect. The chemical-resistant body shrugs off diesel and hydraulic fluid, and the maximum torque setting frees bolts rusted solid since the machine left the showroom.
Industrial Plant and Factory Maintenance
Conveyor systems, presses, and heavy stationary machinery use large fasteners rarely disturbed and often corroded into place. The three-speed control lets you switch between delicate alignment bolts and seized structural fasteners without changing tools, and the ToughSystem case keeps everything protected in a dusty plant environment.
Rail and Marine Maintenance
Rolling stock and marine vessels combine large fasteners with aggressive corrosion from salt, moisture, and constant vibration. The sealed composite body resists saltwater spray, and the cordless format works trackside or dockside where compressed air is not readily available.
Mobile Heavy Repair and Roadside Assistance
A broken-down lorry on the hard shoulder cannot wait for a compressor to build pressure. The CL3.CH18SP2 in its ToughSystem case loads into a service van and delivers pneumatic-rivalling torque from a battery — freeing wheel nuts and driveline fasteners on the roadside without the air-hose tangle.
