Countersink Set 2-20mm 4pc Titanium Coated HSS

A 4-piece countersink set made from titanium coated HSS, covering sizes from 2mm to 20mm for chamfering, deburring and forming countersunk holes. Used where a clean tapered recess is needed for screw heads or where sharp edges need removing after drilling in metal, wood or plastic.

Useful for workshop jobs, fitting work, maintenance and general DIY repairs, this set suits anyone preparing holes for flush fasteners or tidying drilled openings. It can be used for vehicle maintenance, bench work, fabrication, joinery tasks and home repairs where burrs need removing or a neat chamfer helps with assembly and finishing.

The set includes four slotted countersinks for metal, wood and plastic, with round shanks in a spread of practical sizes, helping cover both smaller pilot work and larger chamfering jobs without relying on one cutter for everything. Each piece is supplied with its own stated length, shank size and head size, so buyers can match the cutter more closely to the job in hand. The titanium coated 4241 HSS construction makes them suitable for repeated use across common materials, while the broad 2-20mm range is useful for regular drilling and finishing work where access to different countersink sizes saves time.
