Gold-Twist Drill Flat-Face Geometry Tip

July 01, 2014

Ingersoll Cutting Tools has extended the application range of its Gold-Twist drilling line by introducing a flat-face geometry tip for flat bottom machining, in a diameter range of 8.00mm to 25.5mm (0.312" to 1.012").

The new line reduces the number of tools required to generate a flat-bottomhole from two or three to a single tool, greatly reducing cycle time. The new geometry produces excellent chip breaking and high-precision flat surfaces, according to the company. These new tips are fully compatible with the Gold-Twist's current line of bodies in the same size.

Inserts are available in grade IN2505 PVD multi-layered coating providing high wear resistance, chipping resistance and prolonged tool life.

    flat ( screw flat)

    Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.

  • physical vapor deposition ( PVD)

    physical vapor deposition ( PVD)

    Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.

  • wear resistance

    wear resistance

    Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
