Description
This twelve-piece set contains adjustable countersunk drill bits made from high-speed steel for woodworking use. The adjustable format is intended to allow the user to set the countersink depth or position to suit the screw and material being used, subject to the adjustment mechanism and the task requirements. The set is supplied as twelve pieces, offering a selection for routine furniture making, joinery, repair and general woodwork. Typical applications may include preparing countersunk holes for screw heads, fitting timber components and carrying out workshop projects where a flush or recessed screw finish is required. Users should select the bit appropriate to the screw size and should confirm that the adjustment is set correctly before drilling. When working with wood, users should use suitable support and clamping, and should follow the speed and feed recommendations for the bit and drill being used. The set can be kept in a case or organiser and should be checked for wear, damage or missing pieces before use.
