Applications & Features
Applications
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
TungDrillTwisted and TungDrill-Six type cartridges can be affixed to the same body.
Inserts & Grades

Main Grades
AH7020
- Wear-resistant grade that enables high speed machining in steel and cast iron. Improved machining efficiency with no compromise on tool life.
AH7030
- First-choice grade in all material groups. Extremely fracture resistant, the grade provides predictability in unstable drilling applications that might, otherwise, induce edge chipping.
AH3135
- P30 – P40 / M30 – M40
-
High fracture resistance
-
Suitable for machining steel and stainless steel under general cutting conditions
AH9030
- P15 – P35 / K10 – K25
- High wear resistance
- Suitable for drilling steel and cast iron at high speed
AH6030
- M25 – M35 / S15 – S30
- High fracture resistance
- Suitable for drilling stainless steel and heat-resistant alloy under general cutting conditions
