Description
Overview:
The Countersink Bit Set 3 Piece by Blue Spot (also listed as BlueSpot) is a durable, general-purpose set for neat, flush screw seating in wood and metal. Made from heat-treated carbon steel, the bits are designed to form precise conical recesses and to tidy drilled holes by removing burrs. Supplied in three popular sizes-12mm, 16mm and 19mm-they cover common screw head requirements in joinery, cabinetry, and light metalwork. Each bit uses a universal 1/4-inch (6.35mm) hex shank for quick, secure fitting in hand and power drills with a compatible hex bit holder. Model references include 20310 and B/S20310. Robust construction and consistent cutting performance make this a practical choice for DIY users and trades who need clean, repeatable results.
