The 8-piece BitBuddy set comprises seven 29mm long x 1/4" hex drive (C6.3) MaxxTor bits (1 of each Pz1 and Pz2, one Ph2 and one of each Torx T10, T15, T20 and T25) plus a 1/4" hex magnetic bit holder. Wiha MaxxTor bits are for use in today’s high performance cordless impact drivers. Standard and normal torsion bits are not able to cope with the forces involved when impact screwdriving. MaxxTor bits have a special torsion zone optimised and adapted for each drive. These bits were independently tested and found to last three times the life of a standard bit and double the life of other high performance impact bits. The BitBuddy keeps the bits secure and makes for easy insertion and removal from a bit holder.
