“Amazing Ideas / Facts!”
The TFS Drill uses straight shape cutting edges and double cross-thinning to ensure cutting edge strength and low thrust.
The flute shape is specifically designed for better chip evacuation.
The TFS Drill Type C uses low-thrust thinning and double margins for stable/accurate machining of cast iron.
Both drills feature a dedicated multi-layer coating as a standard to improve wear resistance.

Background / Point for Development
Background
- In the machining of cast iron and steel, thrust resistance was high and chip evacuation was poor.
Thus difficult to improve efficiency to ensure the machining accuracy.
The cutting heat also tends to go high which resulted in short tool life.
Point for Development
- The TFS Drill has a wider twist flute shape for more efficient chip evacuation and the cutting edge shape suitable for machining steel with low cutting resistance.
- The Type.C has a special thinning shape to reduce thrust, specially designed for cast iron machining.
- The double margin minimizes vibration and keeps high-precision during machining, while the use of a multi-layer coating significantly improves service life.
