Professional spline fasteners demand a bit set built to withstand the high torque loads that standard hex or Torx profiles cannot reliably handle. The Draper Expert Spline Bit Set (83567) addresses this directly with bits manufactured from hardened and tempered S2 steel, finished with a shot blasted surface that improves grip and resists corrosion in workshop conditions. The 1/2"" square drive bit holder is constructed from chrome vanadium steel hardened and tempered with a micro satin finish that reduces glare and offers additional surface protection during heavy use. The set is configured to cover a practical range of spline sizes and lengths for both shallow and deep access applications. The five-piece set comprises one bit holder (10mm x 1/2"" square drive) two spline bits in 6mm and 8mm measuring 30mm in length and two spline bits in 10mm and 12mm measuring 75mm in length. The two distinct lengths allow the technician to choose between a compact bit for confined spaces and an extended bit where reach is required. Carrying Draper Expert quality designation this set is suited to automotive and industrial workshop environments where precision drive bits are required for spline-headed fasteners across a variety of applications.
