DoMultiRec – Knuckle – FCD450
IMPROVED TOOL LIFE & COST REDUCTION
Counterbore Machining of Automotive Knuckles
In the conventional process, machining was performed using a special counterbore cutter, but the insert performance was low and tool life was short.
DoMultiRec is a multifunctional cutter that can also be used for counterbore machining, offering long tool life and cost efficiency with its durable four-corner inserts.
