The Panasonic EYC241LJ2G31 18V 2 Piece Kit includes a powerful brushless combi drill and impact driver in a handy case. The Panasonic EY79A3 18V Brushless Combi Drill is a capable and powerful combi drill. Suitable for working at any angle and even under load, the drill adjusts automatically between a fast rotation speed for lighter work and higher torque whenever the load increases. This enables appropriate torque and rotation for any task. The drill features electronic speed control as well as electric brake to your safety. An enhanced LED increases luminosity which delivers a clear view of the work area. For maximum convenience and accuracy, the tapping mode allows automatic reverse without having to change the toggle. Chuck Type 13mm Keyless Chuck Speed Control Variable Speed No Load Speed RPM 1800 Max Torque 50Nm Impact Rate IPM 32,300 The Panasonic EY76A1 18V Smart Brushless Impact Driver with Dash Mode is an impressively compact and lightweight machine that combines both durability as well as speed. The impact driver combines brushless technology with an improved air flow design to give dramatically improved continuous durability under heavy load, such as when driving long screws or drilling into wood using a flute woodboring bit. The improved air flow provides efficient cooling to centre of coils as well as around motor. To help increasing work speed, the EY76A1 features a DASH mode. It allows the unit to reach full speed instantaneously giving maximum performance, ideal for drilling wood without needing pilot holes or super fast driving without damaging screw heads. The base of the device includes storage space for 2x 65mm bits to left and right while two bright LEDs help avoid shadowing on your work. Max Torque 170Nm No Load Speed RPM 2800 Bolt Size M6 - M16 High Tensile Bolt Size M6 - M12 Impact Rate IPM 0-3100 At the heart of these is the brushless motor that allows you to use it efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
