for high-powered drilling and fastening in masonry, metal and wood
Construction professionals that drill holes and drive fasteners into wood, metal or concrete need a cordless hammer drill and driver with the power to tackle a variety of hole sizes plus the compact size to get into tight work spaces. The 18-volt EY7950LR2S hammer drill kit (EY7950X tool only) excels at the variety of jobs electricians, general construction contractors, system installers, heating, water and sanitation technicians do that involve masonry, metal or wood drilling or fastening. At only 5 lbs. with the battery, the tool is easy to use in overhead or far-reaching applications. At only 9-1/4” long x 9-3/4” tall x 2-1/2” wide, the compact tool delivers 478 in.-lbs. of torque, capable of drilling up to ½” diameter holes in metal or masonry or up to 1-7/16” diameter holes in wood. The two-speed transmission produces 50-430 rpm/900-7,740 bpm in low speed and 160-1,650 rpm/2,800-29,700 bpm in high speed. The variable speed and reversible tool has the power to efficiently drive up to 5/16” diameter wood and up to ¼” diameter self-drilling screws. The ½” metal heavy-duty keyless chuck allows easy bit changes, yet holds the bit firmly during drilling, hammer drilling and fastening. An electric brake stops the bit immediately when the trigger is released and an LED light illuminates the work area for accurate drilling or fastening. Workers can select one of 18 clutch settings, which steps up 3.0 in. lbs. from 8.8 to 61 in. lbs., to match torque to fastener driving needs.
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. Its design also allows it to operate under substantial loads, making it less likely to burn out when used for heavy-duty jobs.
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. 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. This charger comes with the kit that includes the tool, two 3.3Ah LR Li-ion battery packs and a carrying case.
Tough tools for tough conditions
The EY7950LR2S 3.3Ah 18-volt hammer drill and driver kit 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.
