Screw bit SIT 1/4 "x 25

Bit screw with torsion SIT


The innovative SIT® Bits are excellently suited for the chipboard screws VELOX® SIT (=AW recess from Würth). You benefit from a significantly improved working comfort, because the screw easily gets stuck on the bit and cannot tumble. The conial form guarantees perfect power transfer: the SIT® Bit centers itself and the flanks transfer even high screw-in moments optimally.

Minimal wear and tear of the 25 mm long bit due to perfect fit between bit and screw.

Choose between small pack with two bits and craftsmen pack with 10 bits – both packed in a robust plastic box with EURO-punching.
