Spiral Flute Taps
• General Purpose Spiral Fluted Taps• Recommended for tapping relatively deep blind holes in materials which produce long curling chips. • The higher flute helix angle increases the lifting action in ejecting chips through the open end of the hole and affords increased ability to span slots or other interruptions.
