The Wera Kraftform Kompakt 20 is a six bit set that is conveniently housed inside the screwdriver handle so you always have the bits you need with you and it comes with a durable, velcro close storage pouch with belt loop. The Bit Holding Screwdriver with Rapidaptor Quick Release Chuck has a telescopic bit holder and their ergonomic Kraftform handle which is made to fit perfectly into the hand ensuring easier, more controlled movement, a button on the base of the screwdriver handle opens the spring loaded compartment to reveal the six bit magazine housed within. The included bits are 1 x PH1 and 1 x PH2 Phillips, 1 x PZ1 and 1 x PZ2 Pozidriv and 1 x 5.5 mm and 1 x 6.5 mm wide slotted screwdriver bits from their tough Z range of screwdriver bits. The bit holder has a strong permanent magnet to securely hold standard 1/4" hexagon drive screwdriver bits, to remove the bit simply push the Rapidaptor Quick Release Chuck forward and it pulls the bit away from the magnet to allow removal, around the chuck is a free spinning sleeve so you can use your non driving hand to steady the screwdriver using the sleeve while your driving hand turns the handle, especially useful when starting a screw. Pushing the green clamping sleeve (between the handle and the chuck) releases the spring loaded telescopic bit holder to extend the length to a full size screwdriver, pushing it in further then either allows you to remove the shaft/blade and bit holder for use in a drill driver or push it back into the handle to collapse the size making it great for working in tight spaces. The Wera Kraftform 20 has a hexagon shaped handle which stops the tool rolling away between uses.
