The Einhell "S" Case measures 175mm x 80mm x 35mm and uses interchangeable inserts which allows the user to add or remove accessories if required. The robust locking clip closure helps to keep contents secure while being transported between jobs, and the transparent lid enables quick identification of the contents when you're searching for the right accessory. This HSS drill bit set contains metric sizes from 2mm to 6.5mm in 5mm increments. Made from robust HSS 4241 steel for durability, the bits have a 135° split point tip which enables fast centering and reduces the required contact force. They feature a type N spiral, which is standardised according to DIN 338 - this enables optimal chip removal and increases efficiency. Designed for drilling into metal, these drill bits will also deliver good performance on a range of other common materials as well. Each drill bit in the set has a standard 1/4" hex shank. This not only stops the drill bit from slipping in a drill chuck but also means they can be used directly in drill drivers which have a 1/4" hex tool holder rather than a jawed chuck.
