DIN Standard General HSS-E Form Tap - M8 to M20x2.5
DIN Standard General HSS-E Form Tap - M8 to M20x2.5
DIN Standard General HSS-E Form Tap
High-speed steel extra (HSS-E) thread forming taps manufactured to DIN standards for medium metric threading applications. TiCN-coated for extended tool life. Form taps create threads by displacing material rather than cutting, producing stronger threads with no chips.

Technical Notes:
- Form tap design displaces material to create threads without producing chips
- Produces stronger threads with improved surface finish compared to cutting taps
- Ideal for ductile materials that can be cold-formed
- 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 3xd chamfer
- Comprehensive range includes both standard and fine pitch options
Applications:
Suitable for thread forming in ductile materials including aluminum, copper, brass, mild steel, and other materials with good plasticity. Produces chip-free threading ideal for blind holes and applications where chip contamination must be avoided. Not suitable for brittle materials like cast iron.
