Protmex Cordless Impact Wrench: High-torque wheel and bolt removal for car and DIY

When failure is not an option, the Protmex Cordless Impact Wrench delivers the muscle required to free seized wheel nuts and stubborn bolts. With 900 ft-lbs (1200 N.m) peak torque, a brushless motor and two 4.0Ah battery packs, homeowners and small-farm users gain quick, repeatable removal without dragging out an air compressor.

⚡ At a Glance

• Torque Output: 900 ft-lbs (1200 N.m) peak torque for heavy-duty loosening
• A win for: Home mechanics and DIYers changing tyres, servicing mowers and light agricultural maintenance
• Avoid if: HGV fleet technicians; repeated high-load removal on semi-trailers will exhaust the 4.0Ah packs and can cause the motor to stall during sustained heavy tasks

High peak torque combined with a brushless motor and three-speed modes. Two 4.0Ah packs and a quick charger enable multiple consecutive jobs with short recharge stops.

Refining bolt removal with brushless motor

Brushless motor technology reaches up to 3,500 RPM across three speed settings (0–2,500 / 0–2,900 / 0–3,500 RPM) and runs quieter and spark-free compared with traditional brushed units. Direct Impact: the higher sustained RPM and efficient motor keep torque delivery steady so stuck nuts come free with fewer bump attempts.

Nail-biting, seized fasteners become manageable and controlled; the variable speeds let users match power to task for neat, damage-free removal. If you have wrestled with rusty wheel nuts, the 900 ft-lbs output strips them free without resorting to heat or multiple hand tools.

Faster turnaround – 2x 4.0Ah batteries and fast charger

Kit includes two 4.0Ah 21V packs and a fast charger that recharges in roughly one to two hours, enabling quick swap-outs during a weekend pit stop. User Scenario: during a set of four tyre changes, a charged spare pack reduces downtime to battery swaps rather than waiting at the charger.

Rapid battery swaps and the short recharge window keep workshop sessions moving and avoid long breaks between wheels. The out‑of‑the‑box kit contains sockets and accessories so work starts immediately.
