Manufacturing Process of Straight Drills

  • 1

    Material Selection

    The manufacturing process begins with selecting the appropriate material based on the drill's intended application. Common materials include HSS, carbide, and cobalt.

  • 2

    Forging and Forming

    The material is forged and formed into the desired shape, creating the drill's body and flutes. This process ensures the drill's structural integrity and initial geometry.

  • 3

    Heat Treatment

    Heat treatment processes, such as annealing and tempering, enhance the drill's hardness and toughness. This step is crucial for achieving the desired mechanical properties.

  • 4

    Grinding and Sharpening

    The drill's cutting edges are ground and sharpened to precise angles, ensuring optimal cutting performance. This step involves using specialized grinding machines to achieve the desired geometry.

  • 5

    Coating Application

    Coatings such as titanium nitride or diamond are applied to the drill's surface to enhance its hardness and reduce friction. This step improves the drill's lifespan and performance in demanding applications.
