Technical Notes:
- Specifically designed for cast iron and other brittle materials
- 2.5° helix angle optimized for short, discontinuous chip formation
- HSS-E construction provides heat resistance and durability
- TiCN coating reduces friction and extends tool life
- 6HX hexagonal shank for secure tool holding
- Conforms to DIN dimensional standards
- Max 2xd chamfer for cast iron applications
Applications:
Specifically designed for threading cast iron, including gray cast iron, ductile iron, and malleable iron. Also suitable for other brittle materials that produce short chips. Not recommended for ductile materials like steel or aluminum - use standard spiral flute or spiral point taps for those materials.
