Technical Notes:
- 15° helix angle provides controlled chip evacuation for softer materials
- Spiral flute design evacuates chips upward, suitable for blind hole applications
- HSS-E construction provides heat resistance and durability
- TiCN coating option reduces friction and extends tool life
- 6HX hexagonal shank for secure tool holding
- Conforms to DIN dimensional standards
- 3P chamfer for general purpose applications
Applications:
Optimized for threading operations in softer, more ductile materials including aluminum, copper, brass, and soft steels. Recommended for blind hole threading where controlled chip evacuation is required.
