14.4DV 4.2Ah Impact Driver Combo Kit with Dual Voltage Technology

EY75A1 Impact Driver
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 EY75A1  ¼" hex cordless impact driver 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 New Panasonic 4.2Ah EY75A1 ¼" impact driver  with Dual Voltage Technology is built to take on both jobs with versatility and power that general construction, HVAC, finish carpentry and electrical installation workers need to do the job efficiently and professionally. This versatile tool features the new Panasonic Dual Voltage Technology which allows the user to use the cordless impact driver as an 18V or 14.4V tool.

EY74A1 Drill and Driver

Construction and maintenance professionals often switch between driving and drilling tasks throughout the day. The Panasonic Dual Voltage Technology 4.2Ah EY74A1 ½" drill and driver kit is built to take on both jobs with versatility and power that general construction, plumbing, finish carpentry and electrical installation workers need to do the job efficiently and professionally. This versatile tool features Panasonic's new Dual Voltage Technology which allows the user to use the cordless drill and driver as an 18V or 14.4V tool.

Tough tools for tough conditions

Like many Panasonic tools, the EY74A1/EY75A1 are Tough IP rated. That means they passed 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. Consult the safety and operating instructions for more information.

Tough and long-lasting battery packs

This tool with "Dual Voltage Technology" can be powered by Panasonic's exclusive 14.4-volt or 18-volt 4.2Ah LS 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 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 4.2Ah LS 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 or 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 55 minutes and fully charge in 70 minutes when charged with the EY0L82B charger.
