The Panasonic EYC242LJ2G31 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 EY75A8 18V Brushless Impact Wrench provides high power and durability in a compact body. The hammer mechanism ensures a compact yet highly durable unit. Tightens to M16 and pre-tightens to M20. Equal torque in forward or reverse means speedy assembly and disassembly. Bumper protection has been increased to reduce wear on housing surfaces, a tougher rubber helps avoid oil and solvent damage to grip areas and new metal battery contact liners for extra durability in serial use applications. Thanks to its compact size, only 143mm in length, this is perfect for using in tight spaces or when using longer sockets. One-push battery level indicator helps avoid work interruptions due to low battery. Even in poorly lit areas, the 3 mode integral LED light can illuminate the working area. No Load Speed RPM 2500 Driving Shank 12in Square Max Fastening Torque 280Nm Impact Rate IPM 3600 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.
