Panasonic has introduced a new 18V high-torque 1/2″ impact wrench (Panasonic EY7552) into their Tough IP line of heavy-duty Li-ion power tools. The new impact wrench is designed to deliver big power in a small package.
- 1/2″ square drive with hog ring and through-hole socket retention
- Up to 346 ft-lbs of maximum torque (4,152 in-lbs)
- Twin Hammer design for increased torque, low vibration, low noise,
- “Smallest-in-class” with <9″ length
- “Lightest-in-class” with 5.7 lbs weight, including battery
- Variable speed trigger
- Electric brake
- Powered by Panasonic’s EY9L51B 18V 4.2 Ah Lithium-Nickel battery packs
- Built-in LED worklight
- Dust and water-resistant to IP56 standards
- Available as bare-tool or kit which comes with (2) batteries and a charger
There are two options – the EY7552X bare-tool, and EY7552Ls2S kit, which includes Panasonic’s GuardION battery cell monitoring system and self-diagnostic universal battery charger.
There are a couple of interesting features to emphasize. With a 346 ft-lbs torque rating, Panasonic’s new 18V impact wrench is not anywhere as powerful as Milwaukee’s new beastly powerful M18 Fuel impact wrenches. That’s not a bad thing, as it does mean the Panasonic 18V impact is lighter and more compact than Milwaukee’s and other brands’ heaviest duty models, and also more powerful than competitors’ most compact lighter duty models.
Panasonic boasts that the new model offers the power and versatility for demanding use at jobsites and in industrial settings, and it doesn’t seem like they’re exaggerating one bit.
The Twin Hammer impact mechanism design also caught my attention, especially since it claims to provide greater torque, faster working speed, greater durability, lower vibration, and lower noise, presumably compared to single-hammer designs. Maybe it lengths runtime as well?
This model seems well suited for general construction needs, automotive maintenance and repair (except perhaps for removing the tightest of lug nuts), industrial use, and other such applications.
There is no word yet about price, but the new impacts will be available starting this month, so more details should be available soon.
