- HSS-E construction provides heat resistance and durability
- TiCN coating option reduces friction and extends tool life
- 6H hexagonal shank for secure tool holding
- Conforms to JIS dimensional standards
- Max 3xd chamfer for general purpose applications
Applications:
Suitable for threading operations in steel, stainless steel, cast iron, and non-ferrous metals. Recommended for blind hole threading where upward chip evacuation is required.
