Introduction:
Features:
Material: Solid carbide (ultra-hard, wear-resistant).
Point Angle: 140° for reduced thrust force and improved centering.
Flute Design: Straight flutes for efficient chip removal in deep holes.
Coolant System: Inner coolant holes (through-tool coolant) to reduce heat and prevent workpiece/tool damage.
Application: CNC machining, mold making, automotive/aerospace parts, and high-precision multi-step drilling.
Coating Options: Optional TiAlN/AlCrN coatings for higher heat resistance.
Longer tool life due to carbide durability and coolant support.
High rigidity minimizes deflection in deep holes.
Multi-diameter steps allow graduated hole sizing in one operation.
Typical Applications:
Drilling, chamfering, and deburring in one pass.
Hard materials (HRC 45+), composites, and exotic alloys.
