Technical Notes:
- Spiral flute design evacuates chips upward, suitable for blind hole applications
- HSS-E construction provides heat resistance and durability
- TiCN coating reduces friction and extends tool life
- 6H shank tolerance for standard tap holders
- Conforms to DIN dimensional standards
- Comprehensive range includes both standard and fine pitch options
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.
