Dormer G2363 6 Piece HSS Straight Shank 90° Countersink Set

The Dormer G2363 is a professional 6-piece HSS countersink set featuring popular sizes for a wide range of drilling and metalworking applications. Manufactured to DIN 335 C standards, this Dormer countersink set includes sizes from 6.3mm to 20.5mm diameter, covering the most commonly required countersinking operations in both professional workshops and home projects.

Each countersink features high-speed steel (HSS) construction with a TiAlN surface treatment for enhanced wear resistance and extended tool life. The straight shank design ensures compatibility with standard drill chucks, whilst the 90-degree countersink angle is ideal for creating precision recesses for flat-head screws and fasteners. All six countersinks are supplied in a protective plastic case for organised storage and easy transport between jobs.

This set is particularly useful for metalworkers, engineers, and fabricators who regularly work with countersunk fasteners across different material thicknesses. The range of diameters makes it equally suitable for joinery applications, furniture assembly, and general maintenance tasks where professional finishing is required.
