The spiral point tap (often called a "gun tap") features a straight flute with an angled notch at the tip that pushes chips forward, ahead of the cut. It is ideal exclusively for through holes-where the hole completely penetrates the workpiece-as it prevents flute clogging and minimizes tap breakage.
Key Features and Uses
Chip Direction:
Drives swarf forward through the hole. Because of this, it should never be used in blind holes, as chips would become compacted at the bottom.
Increased Strength:
Since the flutes are only used to push chips forward, they can be shallower, giving the tap a larger cross-sectional area and making it stronger than spiral flute taps.
Applications:
Excellent for production tapping in ductile materials like aluminum, copper, brass, and mild steels.
