Panasonic EY7940LR2S Tough IP™ Li-ion 14.4-volt 3.3Ah Cordless 1/2" Hammer Drill and Driver Kit
A Cordless Hammer Drill and Driver Kit for Masonry, Metal and Wood Drilling and Fastening
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 14.4 volt EY7940LR2S hammer drill kit (EY7940X 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 3.96 lbs. with the battery, the cordless hammer drill and driver is easy to use in overhead or far-reaching applications.
At only 7-7/8" long x 9-1/8" tall x 2-3/8" wide, the compact hammer drill and driver delivers 390 in.-lbs. of torque and capable of drilling up to 1/2" holes in metal or masonry or up to 1-3/8" diameter holes in wood. The two-speed transmission produces 70-400 rpm/1,260-7,200 bpm in low speed and 200-1,400 rpm/3,600-25,200 bpm in high speed. The variable speed and reversible tool has the power to efficiently drive M5 machine screws and up to 1/4" diameter wood and self-drilling screws.
Workers can select one of 16 clutch settings, which steps up 1.8 in. lbs. from 8.8 to 39 in. lbs., to match torque to fastener driving needs.
An electric brake stops the heavy-duty keyless chuck immediately when the trigger is released; an LED light illuminates the work area for accurate drilling or fastening.

High-Tech Components Deliver Speed, Power and Durability
The cordless hammer drill and driver'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 drill/driver 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 power hammer drill and driver, 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 hammer drills and drivers, 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 cordless hammer drill and driver 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 Li-ion battery packs and carrying case.
Tough Tools for Tough Conditions
The EY7940LR2S cordless hammer drill and driver kit has an IP56 rating that proves the tool's toughness claims. This rating means the drill/driver 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 power hammer drill and driver 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 drill/driver 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 dusty 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.
