Countersink set DIN 335 Type C 90° HSS-Co 5 + cutting paste 50 ml - 6 pcs.

Three precisely matched cutting edges ensure a smooth, controlled countersinking process.

The variable-radius back angle reduces the tendency to chatter. This results in perfectly circular countersinks with a uniform, scratch-free surface.

Optimised chip clearance parameters such as the chip angle, transition radius and extra-wide chip flutes ensure reliable chip and heat removal and contribute to high wear resistance.

The resulting helical chip detaches automatically from the tool, thereby supporting a continuous machining process.

At the same time, the cutting edge geometry counteracts material welding and reduces the resulting axial and radial forces, meaning that significantly less feed force is required.

Depending on the material, machining can be carried out at both high and low cutting speeds – whilst maintaining a consistently high quality of countersinking.

• Circular, burr-free recesses with a uniform surface.

• Over 30% lower feed force for comfortable working.*

• Over 50% shorter machining time with an average countersinking time of 8 seconds.*

• Up to 60% longer tool life.*

*The performance figures given are based on comparative tests with standard countersinks under identical conditions in the company’s own testing and experimental facilities. Test conditions: S235JR structural steel, material thickness 10 mm, countersink diameter 20.5 mm. Results may vary depending on the machine, material, tool dimensions and machining parameters.
