Description

CoroDrill® 861 provides the high stability essential for drilling deep holes, with high speed and efficiency, up to 30xD. ACM (Advanced Chip Management) flute geometry ensures sufficient flute space along the whole length of the tool and encourages small and manageable chips. Unique surface treatment provides a very smooth surface in the flutes to decrease torque. Accurate deep holes to depths of up to 30 × drill diameter, without pecking High speeds and feeds allow greater productivity to reduce cost per hole Achievable hole tolerance H8−H9 Drilling depths: 12−30 × drill diameter Clamp with high precision chucks only A wide range of workpiece materials Conventional drilling, cross holes, angled faces Automotive: crankshafts, engine blocks, cylinder heads
