For Drilling Concrete and Installing Anchors with One Tool
Electricians and other installation professionals will appreciate how the flip of one switch makes the Panasonic EY7840LR2S (EY7840X tool only) SDS-plus cordless rotary hammer and driver kit go between hammering and driving modes. That makes it the perfect tool for drilling holes into concrete, masonry, wood or metal and then driving fasteners to mount lighting equipment, conduit pipe or switch boxes and more. The ½” SDS-plus tool has a cap-piston compressed air system that powers the hammer mechanism. It delivers 0-3,800 bpm with 21.6 kN of hammering force in hammering mode for fast drilling, even in hard concrete. In drilling mode, it delivers 0-1,000 rpm and produces 13-48.7 in.lbs. of torque for conventional drilling or driving. The five torque level settings step 8.8 in.-lbs. with each clutch setting, allowing the user to best match torque to the drilling or fastening job. The slow-start switch, which is protected by a soft rubber cover that keeps dust out of electrical components inside the tool, makes starting holes easier and more accurate. Its ergonomic design makes it easy to use in up, down or to the side drilling and fastening orientations. Weighing only 5.4 lbs. with the 3.3Ah battery and only 9-13/16” long x 10-3/8” tall x 2-33/64” wide, it is well-balanced for one-handed drilling and fastening. A convenient LED light brightens the task for accurate hole positioning and a convenient shoulder strap makes it easy to carry up and down ladders. The tool has an SDS-plus bit adapter that holds hex shank-type bits to make switching between drilling and fastening bits fast and easy. The tool can drill up ½”-diameter holes in steel with a bit or up to 53/64”-diameter holes with a holesaw. In wood, it can make up to 45/64”-diameter holes or drive up to 11/64” diameter screws. In concrete, it can drill up to 5/8”-diameter holes.
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 3.3 AhLR 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 EY7840LR2S/EY7840X SDS-plus rotary hammer 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.
