Designed for optimal cooling and chip evacuation, CYC's rods with helical coolant holes are perfect for high-speed cutting and drilling operations. These rods enhance tool life by reducing thermal stress during machining, ensuring greater precision and efficiency. Available in various configurations, they provide exceptional performance for deep hole drilling and other demanding applications.

Grade MH10F 10% Co and CS43 12% Co (for regular OD only) are available.

By more than 20 years experience of super stirct process control, We offer two holes 30 degree & 40 degree and three holes 30 degree,

Sizes from Ø3 to Ø32 are available for two helical coolant hole.
