CoreLine – Countersink 90°, DIN 335-C ▲ 3 cutting edges to avoid burrs and chatter marks when countersinking and deburring in virtually all materials. Particularly suitable for DIN screws according to DIN ISO 7721 and 7991, as the countersink diameters are matched to the heads of these screws. ▲ the TiN version makes high cutting rates possible; very long tool life and very good friction resistance properties in order to avoid material sticking. ▲ TiAlN version shows considerably improved performance compared to TiN version. Particularly suitable for all abrasive materials (cast iron, AlSi) and/or at high temperature.
