CoroDrill® 862 offers outstanding performance for holes up to 2.95 mm (0.116 inch) diameter. A thin, effective coating helps retain cutting edge geometry and provides a smooth surface for chip evacuation, while even wear formation prolongs tool life for a wide range of materials.
Benefits
High performance in steel, stainless steel, cast iron and aluminum
Engineered tool geometry and surface treatment for efficient chip removal
Good hole entry and exit, tight hole tolerance
Features
ACM (Advanced Chip Management) flute geometry for small and manageable chips
Specially designed point geometry reduces thrust forces
Smooth drill surface enables fast and efficient chip evacuation
Internal coolant holes deliver coolant directly to the tip of the drill even at deep drilling depths
3 mm (0.118 inch) shank diameter throughout the range
Application
Achievable hole tolerance: H8-H9
Suitable for all materials
Drill lengths: 8-12 × drill diameter
Drill diameter range: 1.85-2.95 mm (0.073-0.116 inch)
Use with CoroChuck™ 930 high precision chucks
