Bosch 3 Piece Countersink Bit Set

The Bosch 3 Piece Countersink Bit Set is a set of HSS countersink bits designed for countersinking screw holes and deburring holes in soft materials. The ground countersinks are made from high-speed steel (HSS), giving an optimum surface quality for even work in pliable surfaces. Five 90-degree cutting edges work continuously without chattering and without leaving burrs, so you get clean, consistent results in soft materials. This makes the set a practical choice for carpenters, joiners and fitters who need neat, flush screw heads. The bits are suitable for use on wood, plastics and non-ferrous metals. The cylindrical shank is compatible with three-jaw drill chucks, so they can be used with a standard drill. The set covers 8 mm, 10 mm and 12 mm diameters.
