EY7441LR2S/EY7441X 1/2” Tough IP™ Li-ion 14.4-volt 3.3Ah Cordless ½” Drill and Driver Kit
Features a compact, light body built for heavy-duty drilling/driving jobs
Construction and maintenance professionals often switch between driving and drilling tasks throughout the day. The Panasonic 14.4-volt 3.3Ah EY7441LS (EY7441X tool only) 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. Its compact size – only 7-5/8” long x 9-1/8” tall x 2-3/8” wide – gets it into tight spaces. The tool can produce 390 in.-lbs. of power so it can take on tough tasks such as drilling up to 1-3/8” holes in wood or ½”-diameter holes in metal. In driving mode, the tool can drive M5 machine screws, ¼”-diameter wood and self-tapping screws easily and repetitively. The tool’s beefy four-brush motor puts out power and takes on difficult tasks with much less chance of burning the motor out on jobs users sometimes expect the tool to do. The variable speed, reversible tool has a two-speed transmission that efficiently converts the motor’s power into drilling/driving power. Users will find the 50-430 rpm low speed helpful in deep wood-drilling and -driving jobs, while the 160-1,650 rpm high speed works best in most metal drilling jobs. An electric brake stops chuck spin instantly when the trigger is released. A built-in LED light makes work in dark areas easier and a belt hook keeps the tool close at hand when it’s not in use. The 18-stage clutch lets the user adjust driving force to the job. It adjusts from approximately 4.4 to 39.0 in. lbs. in 2 in. lbs. increments, so driving force matches driving needs without overdriving or stripping fasteners. At just 3.85 lbs. including battery, the tool’s light weight and ergonomic design helps keep the user’s wrist in the neutral position. The light weight and tool design work together to cause less fatigue and improve tool control.
Tools for tough conditions
Like many Panasonic tools, the EY7441LR2S kit/EY7441X (tool only) 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
The tool, powered by Panasonic’s exclusive 14.4-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 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 50 minutes and fully charge in 65 minutes when charged with the EY0L82B charger, The charger comes with the kit that includes the tool, two 3.3Ah Li-ion battery packs and carrying case.
