A-SFT-DH
Spiral Tap for Deep-Hole Applications
In thread depths exceeding 2×D, chips tend to become longer, creating challenges unique to deep-hole tapping. The A-SFT-DH features advanced chip control technology that minimizes chip entanglement and delivers stable chip formation from the hole entrance to the bottom. In addition, its optimized shank length helps prevent chip wrapping and promotes smooth chip evacuation, significantly reducing machine stoppages and improving operational efficiency. Fewer machine interruptions contribute to higher productivity and support labor-saving manufacturing.
