Works hard, stays cool and comfortable and has three power levels that can be matched to the job.

Professional tradesmen must do a wide variety of highly repetitive fastening jobs, and the EY7550LR2S ¼” hex cordless impact driver kit has the versatility, power and runtime to excel in heavy driving, demanding fastening or finish-assembly applications. The cordless impact driver has variable speed and three power settings that make it handy for heavy-power or fine-control jobs such as HVAC installation, auto repair, deck building, lag bolt or finish fastening and more. The High/Hard setting is best for heavy driving jobs such as setting lag bolts, tightening large bolts and nuts or driving long screws. In this setting, it delivers 0-2,500 no-load rpm, 1,370 in. lbs. of torque and 0-3,000 impacts/minute (ipm). The Medium setting is suited for driving self-tapping screws and conduit clip fasteners, delivering 0-1,400 no-load rpm, 1,150 in.-lbs. of torque and 0-2,800 ipm. For delicate fastening jobs that require controlled power and finesse, such as installing hinges on cabinets and fastening wall plates to electrical boxes, the Low/Soft setting delivers 0-1,000 rpm, 355 in. lbs. of torque and 0-2,000 ipm. An electric brake stops the ¼” hex quick-connect bit instantly in all modes; a built-in LED light greatly improves work visibility. Weighing just 3.5 lbs. with battery, the compact tool measures just 2-13/32” wide, 9-17/32” tall and 5-5/8” long. A convenient built-in belt hook keeps the tool handy.


High-tech components deliver speed, power and durability

The tool’s brushless motor, durable switch and sealed control circuits in the tool body and battery pack deliver top power, speed, runtime and long tool life. Because electronics replace brushes in the tool, the tool creates less heat and uses power much more efficiently than conventional motors found in many cordless tools. That means longer runtimes between charges, cooler operation and longer tool and battery life.

Tough and long-lasting battery packs

The tool, powered by Panasonic’s exclusive 18-volt 3.3Ah LR Li-ion battery pack, is built for heavy use, long runtimes between charges and long cycle life. Unlike manganese-based Li-ion batteries used in many cordless power tools, Panasonic’s exclusive cobalt Li-ion battery technology produces less internal heat buildup that can kill battery packs. The battery packs also feature Panasonic’s Solid Solution technology, a proprietary process for dissolving and hardening cobalt and nickel and other key battery components. This unique chemistry dramatically improves battery pack safety, reliability and power output. A special heat-resistant ceramic coating layer separates cells and protects them from heat buildup. Together, the chemistry, battery design and manufacturing process add up to powerful batteries that promise to deliver long running lives.

Battery packs that are smart, too

Sometimes professional users are their own tool’s worst enemy, attempting to push them past their design limits. This can lead to irreversible battery or tool damage. That’s why Panasonic 3.3Ah LR battery pack cells are independently monitored for even discharge while preventing over-charging and over-discharging. An over-discharge sensor prevents the user from running the tool after it reaches the point where too-low voltage output could damage the battery and the tool. Plus, an internal temperature sensor flashes a warning light if internal temperatures rise, and then cuts off tool power if battery temperature reaches critical levels. Water getting into the battery doesn’t have to mean it’s a goner. Panasonic engineers have added vents built in the battery case so water can easily drain out of the battery pack. The battery, which is easy to remove using a simple slide-down release button, can charge to 80 percent capacity in 50 minutes and fully charge in 65 minutes when charged with the EY0L81B charger that comes with the kit that includes the tool, two 3.3Ah Li-ion battery packs and carrying case.



Tough tools for tough conditions

The EY7550X ¼” hex cordless impact driver has an IP56 rating that proves the tool’s toughness claims. This rating means the tool has withstood demanding laboratory tests of working in extremely dusty work environments and the effects of water getting sprayed on the tool by powerful jets. In the field, it assures professional tradesmen have a tool that can stand up to the rigors of hard jobsite use. The IP rating is established by the International Electrotechnical Commission (IEC) and is outlined in IEC 60529. The standard outlines a coding system that indicates the degree of protection an electrical machine’s enclosure offers internal components. Based on objective testing, it assigns a rating to the enclosure’s ability to keep potentially damaging solid foreign objects (dust and contaminants) and water out of the tool under increasingly difficult conditions. The dust protection test subjects the tool to a very dusty environment and then puts it to work to assure the tool was unaffected by dust exposure. In the grueling test, the tool proved that it achieved a dust protection level of five out of six levels; the sixth level is for dust-tight tools. It’s a good indication that the tool’s design keeps potentially harmful contaminants out, assuring long life and top performance that professionals demand. Similarly, the water protection test put the tool up against increasing levels of water exposure. It attained a six out of eight levels rating, withstanding the effects of powerful water jets. Whether it’s extremely dust work conditions or work in damp or wet locations, users will appreciate a tool that will keep working when others would likely fail.

Reviews

EY7550LR2S is rated 3.5 out of 5 by 2.
Rated 2 out of 5 by from Used to be good tools..... 3/1/2012 Just bought this new Lithium-Ion powered impact driver as part of a set. As a first impression, I am very happy with the performance, as it is more powerful and versatile than my last Panasonic impact driver, which was a 12V. The batteries finally died on the 12V after about 6 years of medium use. This 3.3 Ah Li-Ion battery should last longer as well. 5/24/2012 Well, I just removed two stars, since the impact driver (EY7550LR) just failed mid screw installation. I used this tool maybe 10 times since I bought it new in March 2012. The lights still work, but the motor does not run. The closest repair shop is 70 miles away. I guess they just don't make them like they used to. 6/19/2012 Just got the impact driver (EY7550LR) tool back from the authorized repair facility. It turns out that the motor fried. All I was doing was driving a 3" #8 wood screw. To add insult to injury, they made me pay the shipping charges both ways. Now every time I use this tool I will be worried that it will fail again and I will have to repeat this process. Under these circumstances, I cannot recommend this tool and am subtracting yet another star.
