The Clarke X-PRO CAT154 (part 3120168) is a heavy-duty, 1-inch-drive pneumatic impact wrench marketed for large commercial vehicles. Clarke rates its maximum torque at 3,800 Nm (±10%), but that is a manufacturer specification—not an independently measured result or a guarantee for every air-system setup. Its 17.2 kg tool weight and substantial air requirements make compatibility and handling central to a buying decision.
What is the Clarke CAT154?
The CAT154 is a professional air-powered impact wrench with a 1-inch square drive. Clarke describes it as a heavy-duty tool for large commercial vehicles and specifies a rocking-dog impact mechanism, a second side handle, and three forward and three reverse speed settings. Those statements describe the manufacturer’s intended use and features; they do not establish independent durability or suitability for every fastener.
The product is identified as Clarke X-PRO CAT154, product/part number 3120168. The model and part number are useful checks when confirming a listing or looking for compatible equipment.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
What does the 3,800 Nm torque rating mean?
Clarke gives 3,800 Nm (±10%) as the CAT154’s maximum torque rating. Treat it as a manufacturer specification, not a promise that the wrench will produce that torque on every fastener. The available product information does not provide an independent performance test, a measured breakaway-torque result, or conditions under which a user can expect a particular result. Air supply, fittings, hose, socket and the job itself matter when assessing whether the tool suits an application.
Check the air system before buying
The CAT154 is a pneumatic tool, so the compressor and airline must deliver air appropriately at the tool. Clarke’s product page and manual do not express the pressure requirement identically: the product page states 7.8 bar required and 9.8 bar maximum, while the manual lists 113–143 psi (8–10 kg/cm²). Use the full manual for the applicable operating instructions and confirm the requirements with Clarke if the difference affects your setup.

- Check that the airline has at least a 13 mm internal diameter, as specified in the manual.
- Check that the connection matches the manual’s 1/2-inch BSP female inlet.
- Assess delivered airflow at working pressure, including losses through the hose, couplings and other restrictions.
- Do not choose a compressor solely from the 10 cfm average-consumption figure: the manual also lists maximum consumption of 55 cfm, and the available sources do not provide compressor-delivery data for recommending a compressor size.
Reach, size and handling
At 17.2 kg according to the manual, the CAT154 is a substantial tool. Its mass, overall size and second side handle deserve consideration for the positions and duration of the work you expect to do. The manual also lists sound pressure of 91 dB(A), sound power of 102 dB(A), and vibration of 14.9 m/s² with K=2.3 m/s² uncertainty. These are Clarke-declared figures, not independent measurements; consult the full manual for safety guidance rather than inferring exposure controls from the figures alone.
There is an apparent inconsistency in Clarke’s product description: it refers to a “long 720mm anvil,” while the same page lists overall dimensions of 630 × 230 × 200 mm. The stated anvil length is greater than the listed overall length. Confirm the anvil measurement with Clarke or inspect the actual tool before relying on the 720 mm claim for an access or reach decision.

How to judge whether it fits your work
Start with the fasteners and applications you actually need to service, then check the tool and workshop as a system. A 1-inch drive requires compatible 1-inch-drive impact sockets; the available product information does not establish that sockets are included. Compare the required access and reach against confirmed tool dimensions, account for the 17.2 kg stated tool mass, and verify that your airline and air supply meet the manual’s requirements.
When comparing impact wrenches, compare equivalent manufacturer metrics rather than treating maximum torque labels as measured outcomes. Drive size, socket compatibility, mass, access geometry, air pressure and consumption, speed settings, and published noise or vibration values can help distinguish models when comparable information is available. No independent comparative performance result is established for the CAT154 here.
