The Wiha Drive-loc systems offers you the flexibility of changing the length of your driver blade and type of bit, while keeping the same handle in your grasp. The hex blades are lined with spherical dimples where the handle ‘locks’ into at your specified length. The double ended blades are adjustable to form a 1.7″ blade to a 4.8″ blade in 1/8″ increments.
System 6 or Drive Loc VI
Our System 6 is the standard blade size. It’s equivalent to a 6mm bit. It is available in sets as well as individual handles, blades, and blade sets.
System 6 Sets
System 4 Drive-Loc
Our System 4 Sets are the precision version of this system. Its blades measure 4mm in diameter, but still have the adjustable length.
