Special thread portion design with thread crests ground off Recommended Tapping Speeds depending on Materials and a few full threads left unchanged. Spiral Pointed Taps (for through hole)  Combination of this design and the special flute geometry Free cutting and Carbon steel and Medium alloy steel and High alloy steel maintains good chip ejection and reduces friction. The structural steel low alloy steel heat treated steel IS P IS P IS P IS P Spiral Fluted Tap is adopting the optimum coating for the 10〜25 10〜25 10〜25 10〜25 tapping condition.
