Description
This eight-piece twist drill bit set contains bits covering the 3–10 mm range (approximately 0.12–0.39 inch) and is supplied with a hex shank for use in compatible chucks and quick-change holders. The bits are made from high-speed steel with a titanium coating and feature a serrated side-cutting form intended for hole enlargement and side cutting in suitable materials. The set is intended for use on plastic, metal and wood, subject to the correct speed, feed and tool being selected for each material. The hex shank format may suit users who move between a drill chuck and a compatible quick-change adapter during a task. Typical applications include workshop drilling, installation work, repairs and general hole preparation where a range of diameters is useful. Users should confirm that the shank fits the tool being used and should select the appropriate diameter for the fixing or opening required. The eight pieces can be stored in a bit case or tool roll between tasks.
