CoroDrill® 865 geometry offers increased productivity and stable drilling of deep holes up to 30 times the cutting diameter. Optimized for cast iron, steel and aluminium, CoroDrill 865 offers high penetration rates, repeatability and process security. New CoroDrill 865 allows your machine to run at full capacity, producing precise oil holes up to 30 times the cutting diameter with high reliability and excellent chip control. CoroDrill 865 is tailored to precise requirements, allowing dimensional adjustments of flute and overall lengths for optimum hole making performance. We’ve designed the CoroDrill 865 with a geometry and flute profile to improve chip formation and increase strength. The flutes have a polished surface to aid chip evacuation and reduce thrust forces whilst the edge preparation refinement ensures consistency. Optimised for deep holes and inclined holes Length up to 30 x DC CoroDrill® 865 can be applied in many applications and components across multiple industries. Suitable for optimised deep hole drilling in components such as connecting rods, crank shafts and engine components ISO-K, ISO-P and ISO-N material specific geometry and grades Dedicated pilot drills
