Applications & Features

Applications

DrillingCoolant hole

Features

1. Rich line-up of drills and Suitable for various applications

  • Drill diameter: ø12.5 – ø 54.0 mm
  • L/D = 2, 3, 4, 5

A wide variety of chipbreakers and grades offers high versatility.

2. Excellent chip evacuation


Coolant hole increases coolant flow by 1.5 times, which improves chip evacuation, resulting in excellent surface finish.

3. TungDrillBig

Drill body with adjustable cartridge covers hole diameter ranges from: øDc: ø55 mm – ø80 mm, L/D = 2.5

  • Highly rigid body and optimized insert position

    Provides well balanced cutting forces and stable machining conditions for highly accurate hole making.

  • Adjustable tool diameter

    TungDrillBig features 5 drill body sizes that can accommodate a range of setting plates covering a diameter range from ø55 mm – ø80 mm.

  • Variety of design options

    TungDrillTwisted and TungDrill-Six type cartridges can be affixed to the same body.
