High Helix Spiral Flute Taps
High helix taps provide exceptional lifting action when tapping deep blind holes in ductile material.
- Provides greater lifting action, especially when tapping deep blind holes in ductile materials
- A built-in higher hook provides excellent shearing action
- Manufactured to Table 302 standards
High helix taps have built in higher hook angles which assures excellent shearing action in soft ductile materials. Designed to tap close to the bottom of blind holes in soft materials, these tools cut freely and allow adequate coolant to reach the cutting surfaces.
