Indexable drill with economical 6 cutting edges insert

6 cornered insert with high performance that’s an extremely economical solution

Applications & Features

Applications

Drilling

Features

1. Double-sided insert with 6-cutting edges

• TungSixDrill is the first indexable drill in the world to adapt double-sided inserts with 6-cutting edges, reducing the insert consumption for the customers.

2. Low cutting force even with double sided insert

• The cutting forces are almost equal to competitors positive single sided inserts, especially at higher feed rates, thus complementing higher productivity.

3. Enhanced corner of central insert

• The central corner is strengthened by an obtuse angle relief thus increasing the corner strength and reliability.

4. 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

    TDX and TDS type cartridges can be affixed to the same body.
