Countersink Drill Bit Set 6.3-20.5mm 6pc HSS Titanium

A 6-piece countersink drill bit set covering sizes from 6.3mm to 20.5mm for producing clean chamfers and preparing flush screw holes. Made from HSS with a titanium coating, these bits are suited to work on wood, carbon steel, sheet steel, fibre board and PVC.

Used for drilling and fitting work where screw heads need to sit neatly below or level with the surface, this countersink drill set is handy for joinery jobs, workshop use, home repairs and general fabrication. It suits buyers working on timber projects, sheet material, plastic components or light metal jobs where a tidy finish matters. Whether you are fitting screws into wood panels, easing edges on drilled holes or carrying out regular maintenance, the range gives useful coverage for common countersinking tasks.

The set includes six countersink sizes: 6.3, 8.3, 10.4, 12.4, 16.5 and 20.5mm. Each bit has a round shank, with shank diameters matched to size, and compact overall lengths from 37mm to 47mm. That makes them practical to keep together in a toolbox or workshop drawer for repeated use when different hole sizes come up. The spread of sizes also helps reduce the need to stop and search for separate bits when moving between smaller and larger fixing jobs.
