The Micro-Tec 20.5 mm Metric HSS Countersink 90° Three Flute is a precision cutting tool designed for clean, accurate countersinking and chamfering in professional machining and fabrication applications. Manufactured from high-speed steel (HSS), this countersink delivers excellent cutting performance, heat resistance, and long tool life.

The 90° cutting angle makes it ideal for preparing holes for flat-head screws and bolts, while the three-flute design ensures smooth material removal, reduced chatter, and an improved surface finish. Suitable for use on steel, aluminium, brass, plastics, and other machinable materials, this countersink is a versatile addition to any workshop or toolroom.

Engineered for accuracy and durability, the Micro-Tec HSS countersink provides consistent results in both hand drilling and machine-assisted operations.
