Material - Spiral Flute Drill Tap is made from M35 High Speed Steel with 5% cobalt, which increases hardness, strength and heat resistance for efficient and reliable cutting performance. The hardness of HSS M35 after heat treatment is higher than HSS 6542 (M2).The Aluminum Titanium Nitride (AlTiN) coating can effectively improve the high-temperature processing life of taps and provide higher surface hardness.
Feature - Spiral flute drill thread tapping tool specially designed for thread cutting of standard size screws discharge chips upward quickly in a spiral shape, which provides clear and tidy without burrs for efficient threading, especially important when tapping blind holes.
Application - Spiral flute tap are most commonly used for tapping blind holes and recommended use in metals that result in curled or brushed chips (aluminum, brass, copper, stainless steel, steel, etc) for creating precise and durable internal threads in metalworking industries and applications, ensuring accurate results on ordinary lathes, drilling machines, and tapping machines.
