The Panasonic EY74A3 Smart Brushless Drill Driver automatically adjusts between a fast rotation speed for lighter work and higher torque whenever the load increases. This enables appropriate torque and rotation for any task. For maximum convenience and accuracy, the new 'tapping mode' allows automatic reverse without having to change the toggle. Fitted with an aluminium bodied chuck and tungsten inserts for ultimate grip and long life. These ultra-hard tungsten inserts are brazed into chuck jaws providing increased gripping power and protecting against wear. It has a lightweight design with improved ergonomics. The base of the device includes storage space for 2 x 65mm bits (left and right). There is also an LED work light for working in dark areas. LED intensity has been improved by 150% (compared to EY74A2), giving a clear view of the bit. Compatible with both 14.4V and 18V Panasonic batteries.
