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.
