Screwdriver bits TX15x25 mm are designed for fasteners with slots of 6-point-star shape that have the same parameters. They are made from steel of increased hardness so that their service life is much longer. Smooth beams provide increased practicality and durability so that you are able to avoid the following: a screw is jammed, the bit pops out of the slots on the product head. However, such a mechanical joining of a tip and a fastener is more reliable and efficient. Bits can be installed in both collet and cam chucks.
