- Standard: DIN 371 (Machine Taps), DIN 376 (Dimensions)
- Type: Spiral Flute
- Coating: TiCN (Titanium Carbonitride)
- Thread Standard: Metric ISO
- Shank Type: 6HX (Hexagonal)
Available Sizes:
M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20, M22, M24

Technical Notes:
- Spiral flute design evacuates chips upward, suitable for blind hole applications
- HSS-PM construction provides improved toughness and wear resistance compared to standard HSS
- TiCN coating reduces friction and extends tool life
- 6HX shank compatible with standard tap holders
- Conforms to DIN 371 and DIN 376 dimensional standards
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.
