    Grades

    KDF400

    KDF400

    Composition: CVD diamond coated fine-grain carbide.
    Application: First choice for machining carbon-fiber reinforced polymers (CFRPs). The crystalline diamond-coated grade offers a high degree of abrasive wear resistance. Paired with sharp cutting geometries and low-axial thrust point geometries, this grade is perfectly suited to machine most CFRPs.

    Features and benefits

    • SPF drills for composite (CFRP) materials.
    • Material-specific SC drill to machine carbon fiber-reinforced polymer (CFRP) composite materials by minimizing delamination and increasing tool life.
    • SPF drill-point design with special 90° point angle increases centering capability.
    • KDF400™ grade is a CVD multilayer diamond coating that provides more wear resistance and reduced friction, increasing tool life, and improving chip flow.
