【Product Name】The DHF MG 0.6 5D Micro Carbide Drill (SKU: AYCDHDBM) is a precision tool specifically engineered for 5-times diameter (5D) hole processing. It effectively addresses chip packing and thermal expansion in deep, small-diameter applications.

【Key Features & Benefits】

• Coolant-Through for 5D Depth: Features internal coolant ports that deliver high-pressure fluid directly to the 5D hole bottom. This is critical for clearing chips in narrow flutes and preventing tool breakage—a practical recommendation for high-precision deep drilling.

• G10 Coating & 28° Helix Efficiency: Enhanced with G10 coating for high wear resistance and lubricity. The 28-degree helix angle optimizes chip lift while maintaining the necessary stiffness for materials up to HRC52.

• Premium MG 0.6 Micro-Grain Substrate: Crafted from ultra-fine MG 0.6 carbide to provide exceptional fracture toughness, ensuring tool integrity during the harmonic stress of 5D deep machining.

• 140° Point Angle for Center Accuracy: The 140-degree point angle improves self-centering capability and reduces axial thrust, ensuring excellent hole straightness and dimensional accuracy over the entire 5D length.

【Applications & Usage】

• Primary Applications: Ideal for 5x diameter (5D) micro-drilling in electronic components, mold inserts, and precision mechanical parts.

• Recommended Materials:

  • ISO P (Steel): Ensures stable and accurate deep drilling in structural steels under HRC30.

  • ISO K (Cast Iron): Provides exceptional durability against abrasive, powdery chips.
