The Panasonic EY7441 cordless drill driver is one of the most comfortable and ergonomic tools on the market. It may only have a 14.4 volt battery pack but it is still capable of drilling up to 35mm in timber, and the 4.2Ah battery capacity allows the tool to put in up to 1200 screws per battery charge. A LED light as standard on the tool allows the user to illuminate the work piece in dark areas and cupboards etc. for easy use in any scenario. The tool is also manufactured with all the usual extras you would expect from a Panasonic cordless such as speed control, electric brake, belt hook and soft grip to name a few.
