This 13 Piece Wiha slimVario® electric Screwdriver and Nut Driver Set covers the most common screw connections with its selection of nut driver inserts and the two slimBits, making it flexible in its use. Thanks to Wiha slimTechnology, the contained slimBit blades are up to 33% slimmer and can thus also easily reach deep-set screw and spring elements. The 1/4in nut driver inserts can be used in combination with speedE® and slimVario® handles to tighten and loosen hex screws. The fully insulated tools prevent potential short circuits caused by unintentional contact, even in confined working environments. Each tool in the set has undergone an individual piece test as per the international IEC 60900 standard, allowing users to work safely on live parts up to 1,000 V AC. Safely stored away and tidily arranged in a robust folding bag. Contains the following: 1 x SoftFinish® slimVario® electric Bit Holder Screwdriver. 1 x slimVario® electric Extension for slimBits 6.0mm. 1 x slimVario® electric Adapter for 1/4in nut drivers. 2 x 75mm slimBit electric Slotted Bits: 3.5 & 5.5mm. 8 x 1/4in Insulated Hex Nut Driver Inserts (Length: 42mm) : 5.0, 5.5, 6.0, 7.0, 8.0, 10, 11 & 13mm.
