This 40 piece bit set contains a great selection of assorted torx, hex and spline bits. Made from solid Chrome-Vanadium steel, these tarnish resistant bits are built to last. We have also included two socket adaptors in this kit for ease of use with your existing sets. All of this comes packaged in a solid moulded plastic case. Perfect for any home workshop or garage. But for heavy professional use we’d suggest Wessermann 40 Piece Torx, Hex & Spline Bit Set.
