Countersink Set HSS-Co 5% – Projahn with 5 cutting edges

Countersink Set HSS-Co 5% – precise tool for clean countersinks

The countersink Set HSS-Co 5% is a high-quality tool for precise countersinking, counterboring and deburring work. The 6-piece set impresses with an innovative five-cutting-edge geometry, which enables clean surfaces, high dimensional accuracy and a long tool life even in demanding applications.

The cutting force is distributed evenly over five cutting edges. As a result, the tool works with particularly low vibration and produces precise countersinks without chatter marks. The unequal spacing of the cutting edges additionally ensures even wear. At the same time, the feed rate is reduced, which significantly increases the tool life and supports a constantly high machining quality.

Even with hand-held drills or drilling machines, precise countersinks up to a diameter of 40 mm can be produced. The 3-flat shank ensures reliable power transmission and prevents the tool from slipping in the drill chuck. This ensures a secure fit and supports controlled workflows even under higher loads.

The set is suitable for stainless steel (HSS-Co 5 %), steel, non-ferrous metals, aluminium, cast iron and plastics. Whether preparing screw seats, countersinking holes or deburring workpieces – the tool delivers clean results in a single operation. The robust model and the precise cutting-edge geometry make the countersink Set HSS-Co 5% a reliable solution for professional machining tasks.
