DoPent – EGR Bulb – AH120
IMPROVED TOOL LIFE
Long tool life
- Required surface roughness of the workpiece was Rz12.5. DoPent machined the doubled number of workpieces compared to the competitor and achieved the required surface roughness due to AH120 grade and chipbreaker with C-Class accuracy.
Smooth machining
- DoPent machined the workpiece smoothly even on a low-powered machine.
