Amazing facts!
── Introducing ideas and technologies ──
The TFH drill ensures low thrust and stable machining accuracy thanks to special thinning and double margins, and enables high feed rates equivalent to 15% of the drill diameter.
Highly efficient machining contributes to increased productivity in a wide range of application areas.
Low cutting resistance (thrust)
Good!
Diameter expansion allowance
Good!
This is the point!
Low cutting resistance and stable machining accuracy
Excellent!
- Special pockets: Wide chip pocket for excellent chip evacuation performance
- Double margin: Ensures stable machining accuracy
- Thinning shape: Newly developed thinning shape with high centripetal force and chip evacuation and low resistance
- DLC coating: Excellent anti-welding performance for aluminium alloys
Development / product concept
“Current status and challenges”
- High efficiency and reduced cutting resistance are essential in drilling in order to reduce investment in equipment and the size of machine tools. Conventional twist drills have high thrust and poor chip evacuation, making it difficult to reduce machining time
“Development points”
- The TFH drill features a newly developed thinning shape for low thrust and a special flute shape for improved chip evacuation, enabling high feed rate of drill diameter x 15% (mm/rev)
- The double margin ensures stable machining accuracy and contributes to improved productivity in a wide range of applications
