We've employed our proprietary high-rigidity cross-section shape to optimise flute thickness.
Furthermore, by increasing the size of the chip pocket on the flute sweep side, we achieved both good tool rigidity and chip ejection.
The flutes have been smoothed to improve chip ejection. This allows L/D = 10 deep holes to be bored without *stepping.
*Non-step drilling of horizontal holes by lathe or horizontal M/C is not recommended.
Stable processing and long service life have been achieved for non-step drilling of even small diameter deep holes.
Manifests good biting performance compared to conventional products, enabling high precision machining with minimal hole
