Straight Fluted Tap Series Spiral Fluted Taps (for blind hole) AXE-HT AXE Straight Fluted Taps Spiral Fluted Taps (for through hole) Specification Coating Spiral Pointed Taps (for through hole) Recommended Tapping Speeds depending on Materials Aluminum alloy Si IS 10〜20 (m/min) Straight Fluted Taps For icon explanation, refer to P.50 Product features ●In tapping Aluminum Alloy Castings and similar, AXE-HT realizes a huge improvement in its endurance due to the proprietary flute design. Cemented Carbide Taps ●Special cutting edge design drastically reduces damage on the cutting edge. Combination of premium powder HSS (featuring high wear resistance and heat resistance) and special coating brings out 5 times longer tool life than previous taps designed for aluminum. ●Stable and strong cutting edge allows high accurate internal thread with optimal surface finishing. ●Most preferable combination of negative rake angle and eccentric relief enables AXE taps to be applicable in wider range of Roll Taps cutting speed, from middle speed to high speed.
