Professional Torque. Brushless Precision. Built for the Job Site.
- 350 Nm Maximum Torque with 3-Speed Control: The EW-B350 delivers up to 350 Newton-metres of maximum torque through a mechanical 3-speed transmission offering selectable speeds of 0–960, 0–1800, and 0–2400 RPM, paired with impact frequencies of 0–1240, 0–2340, and 0–3120 impacts per minute. This gives the operator precise control over driving power — from delicate fastening tasks to maximum-force bolt removal — without over-torquing or stripping fasteners.
- High-Efficiency Brushless Motor with Metal Gearbox: The brushless motor eliminates carbon brushes, dramatically reducing friction and heat generation, which translates to more energy directed into torque output, a longer motor lifespan, and reduced maintenance requirements. Paired with a robust metal gearbox, the drivetrain ensures smooth, efficient power transmission and enhanced durability under sustained heavy-duty use.
- Compact, Lightweight Design at 1.8 Kg (Incl. Battery): Weighing just 1.8 kg including the battery and charger, the EW-B350 is engineered for low operator fatigue during extended use. Its super compact form factor allows access to tight spaces and confined areas where larger impact wrenches cannot reach, making it ideal for under-vehicle work, panel installations, and confined mechanical bays.
- 20V 2.0Ah Lithium-Ion Battery with Power Indicator: Powered by the IDU BT20-2A 20V 2000mAh Lithium-Ion battery, the tool delivers consistent, fade-free power throughout the discharge cycle. The integrated LED battery level indicator provides real-time charge status, eliminating unexpected shutdowns mid-task. The included IDU CH60-2A 2.4A standard charger (220–240V, 50/60Hz, Type G plug) ensures fast, reliable recharging between uses.
- 1/2" Square Drive Anvil with Friction Ring System: The 1/2-inch square drive anvil features a friction ring retention system for secure, tool-free socket changes, compatible with the full range of standard 1/2" impact sockets. This drive size is the industry standard for automotive and industrial fastening, providing broad socket compatibility across metric and imperial sizes.
- Built-in LED Work Light, Double Insulation & Integrated Carry System: The built-in LED work light activates to illuminate dark workspaces such as engine bays, under-stair cupboards, and confined mechanical areas. Double insulation construction ensures the electrical components are fully isolated from the outer casing, providing an additional layer of user safety. The tool also features an integrated heavy-duty carrying strap and metal belt clip for hands-free portability on the job site, and ships in a durable PVC carrying case for secure transport and storage.
The IDU EW-B350 Cordless Impact Wrench Kit is supplied complete with the machine, a 2.0Ah 20V Li-Ion battery (IDU BT20-2A), a 2.4A standard charger (IDU CH60-2A) with Type G plug, a metal belt clip, an integrated carrying strap, a PVC carrying case, and a guide book — everything required to begin work immediately out of the box. This product has been independently tested and certified to CE (Machine Safety Test), CB (Comprehensive Machine Test), and RoHS (Restricted Hazardous Substances / Raw Materials Test) standards, confirming compliance with international safety, performance, and environmental regulations.
General Purchase & Comparison Queries
What is included in the IDU EW-B350 Cordless Impact Wrench Kit?
The IDU EW-B350 Cordless Kit is a complete, ready-to-use package. It includes the EW-B350 brushless impact wrench machine, one 2.0Ah 20V Lithium-Ion battery (IDU BT20-2A), one 2.4A standard charger (IDU CH60-2A) with a Type G (British 3-Pin) plug rated for 220–240V, a metal belt clip, an integrated carrying strap, a PVC carrying case, and a guide book. No additional purchases are required to begin work immediately.
How does the IDU EW-B350 compare to a brushed cordless impact wrench?
The brushless motor in the EW-B350 offers significant advantages over conventional brushed motors. By eliminating carbon brushes, the motor produces less friction and heat, which means more energy is converted into usable torque rather than being lost as heat. This results in longer runtime per charge, a longer motor lifespan, and lower maintenance requirements over the tool's life. For professional users who rely on their tools daily, the brushless design delivers a measurably better return on investment.
Is the IDU EW-B350 suitable for use in the UAE and GCC region?
Yes. The included IDU CH60-2A charger operates on 220–240V at 50/60Hz and is fitted with a Type G (British 3-Pin) plug, which is the standard plug type used across the UAE, GCC countries, and the UK. No plug adapter is required. The tool itself is battery-powered and operates independently of mains voltage, making it fully compatible for use throughout the region.
Product-Specific and Usage Queries
What does the 3-speed mechanical transmission do, and when should I use each speed?
The 3-speed mechanical transmission allows you to select the optimal balance of torque and speed for each task. Speed 1 (0–960 RPM / 0–1240 IPM) delivers maximum torque at low speed — ideal for heavy bolt removal, lug nuts, and high-resistance fasteners. Speed 2 (0–1800 RPM / 0–2340 IPM) is the all-purpose mid-range setting suited for general fastening and assembly work. Speed 3 (0–2400 RPM / 0–3120 IPM) provides maximum speed for rapid driving of lighter fasteners where torque demand is lower. Selecting the correct speed reduces the risk of over-torquing and extends battery runtime.
What size sockets are compatible with the EW-B350's square drive?
The EW-B350 features a 1/2-inch square drive anvil with a friction ring retention system for secure, tool-free socket changes. It is compatible with the full range of standard 1/2" impact-rated sockets in both metric and imperial sizes. It is important to use impact-rated sockets (typically black phosphate finish) rather than chrome hand-tool sockets, as impact forces can crack non-impact-rated sockets and create a safety hazard.
How long does the 2.0Ah battery last, and how long does it take to recharge?
Runtime depends on the application and speed setting selected. Under typical mixed-use conditions, the 2.0Ah 20V Lithium-Ion battery (IDU BT20-2A) provides sufficient runtime for most standard fastening tasks. The LED battery level indicator on the tool provides real-time charge status so you are never caught off guard. The included IDU CH60-2A 2.4A standard charger recharges the battery efficiently — for extended work sessions, having a spare IDU BT20-2A battery on hand is recommended to maintain uninterrupted productivity.
Problem/Solution-Oriented Queries
The impact wrench is not loosening a seized or heavily corroded bolt — what should I do?
For seized or heavily corroded fasteners, first ensure the tool is set to Speed 1 to maximise torque output at up to 350 Nm. Apply a penetrating lubricant (such as a rust-release spray) to the fastener and allow it to soak for several minutes before attempting removal. Ensure you are using a correctly sized, impact-rated 1/2" socket that is fully seated on the fastener to prevent rounding. If the fastener remains immovable, the issue is likely mechanical (corrosion weld or thread damage) rather than a tool limitation, and further mechanical intervention may be required.
The LED battery indicator is showing low charge very quickly — is the battery faulty?
Rapid battery discharge can occur for several reasons. First, confirm the battery was fully charged before use — the IDU CH60-2A charger indicator will confirm a complete charge cycle. Operating consistently at Speed 3 (maximum RPM) under heavy load will drain the battery faster than lower speed settings. If the battery is new and still discharges unusually quickly, allow it to complete 2–3 full charge and discharge cycles to reach optimal capacity. Lithium-Ion batteries also perform best within normal ambient temperature ranges — extreme heat (common on UAE job sites) can temporarily reduce effective capacity.
The socket keeps slipping off the anvil during use — how do I fix this?
The EW-B350 uses a friction ring retention system on its 1/2" square drive anvil to hold sockets securely in place. If a socket is slipping, first inspect the friction ring for wear or damage — a worn ring will not grip the socket effectively and should be replaced. Ensure the socket is fully pushed onto the anvil until it clicks into the retention groove. Also verify you are using impact-rated sockets, as some aftermarket sockets have slightly undersized square drive openings that do not engage the friction ring correctly. Contact your IDU authorised service centre if the friction ring requires replacement.
