1. As designed by left hand flute, chip will be evacuated to front side and the product can do a guide during process.
So it is excellent in straightness, tolerance and surface roughness. It is suitable for guide hole machining of mobile mold, electronics mold and auto-parts mold.
2. In case of deep hole machining, this is the only tool which can replace grinding process.
By adoption of the eccentric technology on cutting edge, there is no trembling at the first step of machining and so it limits run-out and is suitable for long time machining.
