Screwdriver bit set KWB 128540 — 5 pieces, flat tips, 28 mm

KWB 128540 is a set of five micro flat (slotted) screwdriver bits with a 28 mm working length, intended for use with bit holders and electric or manual screwdrivers. The bits are made from high-quality TQ 60 steel and have a satin surface finish. Their compact extra-long 28 mm design makes them suitable for reaching screws in confined or hard-to-access locations while the 4 mm hexagon shank fits standard bit holders.

Advantages

High-strength TQ 60 steel ensures wear resistance and dimensional stability, while the satin finish reduces glare and provides a consistent surface. A practical fastening strip keeps the bits organized and accessible.
