EY7552 Heavy-Duty Impact Wrench 18V 2 x 5.0Ah Li-ion – Grey – One Size – The Panasonic EY7552 1/2in Heavy-Duty Impact Wrench has an improved twin hammer block design that allows for a smaller size and lower weight, but also provides reduced vibration and noise levels, making it a comfortable, hard-working tool. The EY7552 offers approximately 230% higher power with almost 50% less vibration and most compact in the high power class when compared with EY75A2 impact wrench. This also helps to protect against damage to the unit itself where repeated contact with the floor or work station causes wear. To reduce the risk of battery power running out, users can check the power level status using the battery capacity level indicator when preparing to take the unit to remote or high-level areas with no access to a power source. Fitted with a 'C spring' type retainer ring, meaning sockets can be fitted easily and can be changed quickly. It's important not to use sockets without a pin facility option. For the strongest, safest socket attachment, use a pin and rubber ring retainer. The 'C spring' retainer is for temporary socket attachment only.
