Carbide Drill Bits
The DS170C carbide drill bit features a cutting edge designed with a curved profile and a chamfer, providing maximum corner stability when drilling through hard materials. This design prevents chipping of the cutting edge, thereby avoiding premature wear. The unique flute design and robust web enhance the drill's strength in demanding applications involving short chips. The DP170C series features a 15° helix angle to maximize stability in applications involving materials with a hardness of 54 HRC or higher. Composed of a special fine-grained cemented carbide matrix, it offers even greater hardness. It features a high-temperature-resistant and impact-resistant TIALN coating, making it suitable for machining hardened materials to extend tool life.

Design details engineered for accuracy, tool life and process stability.
The DS170C series features a unique grooved design and a robust web, which enhance the drill's strength in demanding applications involving short chips. It has a 30° helix angle, which improves chip evacuation at higher length-to-diameter ratios.
The DS170C series is composed of an ultra-fine-grained tungsten carbide alloy matrix, which offers higher hardness. It features a high-temperature-resistant and impact-resistant TIALN coating, making it suitable for use on hardened materials to extend tool life.
Grinding is performed using a German Walter five-axis grinding machine. The cutting edge is designed with a curved profile and a chamfer, ensuring maximum corner stability when machining hard materials.
The DS170C series features a superior design with long cutting edges optimized for rigidity. The cutting edge tips are designed with an R-radius for protection, and the cutting edge band is passivated. This provides efficient and precise cutting performance for rough machining.
The carefully designed double-edge geometry provides performance and stability when drilling intersecting holes and/or drilling holes on sloped or irregular surfaces.
The DS170C Series (without through-coolant) is specifically designed for machining work-hardened and surface-hardened materials using overflow coolant.
Pre- and post-polishing processes reduce friction and ensure excellent chip management
