AT Spiral Fluted Taps

AT spiral fluted taps (spiral flute taps) are threading taps designed to cut internal threads while helping manage chips during tapping (application dependent). Spiral flute designs are commonly selected for blind holes and applications where chip evacuation and thread quality are important, especially when compared to tap styles intended to push chips forward. As with any tapping operation, the best results come from matching the tap to the hole type, thread standard, and material.
