The spiral flute geometry directs chips upward, eliminating clogging and thread damage from trapped chips at the bottom of blind holes. It ensures smooth machining even in deep blind holes, improving thread finish and reducing downtime for chip removal.

The spiral point (gun nose) geometry directs chips forward, eliminating clogging and thread damage from trapped chips. It ensures smooth machining even in deep through holes, improving thread finish and reducing downtime for chip removal.

The straight flute geometry allows bidirectional chip evacuation, making it suitable for both through and blind hole tapping (especially effective with short-chip materials). This universal design covers most standard threading
