Take a closer look
Solid carbide performance optimized for precision, stability, and long production cycles.
-
Optimized Point Geometry+Multi-faceted point geometry improves self-centering and lowers thrust load at entry. Geometry can be tuned for carbon steel, stainless steel, cast iron, and non-ferrous materials.
-
Stable Margin & Flute Design+Flute and margin profiles are balanced for chip evacuation and hole-wall stability, reducing vibration and helping maintain straightness in longer depth ratios.
-
Ultra-fine Carbide Substrate+Premium micro-grain carbide supports both edge toughness and wear resistance, giving more stable performance across high-volume production and difficult materials.
-
Flexible Coating Routes+TiSiN Coatings are sourced through a Sandvik1-acquired coating facility in China for standard production runs, and Oerlikon Balzers6 (Switzerland) for demanding applications...
