YG-1 T4 series high vanadium HSS spiral pointed combo tap for multi-purpose. Reduces tap breakage, ensures accurate thread depth. Eliminates loose threads due to tap overfeeding. Improves thread quality and chip evacuation. Allows tapping of many metals including stainless steel and steels. Eliminates "bird nests" around tap shank. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Titanium carbonitride coatings are harder and more wear-resistant than TiN for improved tool life and faster cutting speeds. Round shanks allow use with a wide variety of toolholding systems. Straight flute tools allow chips to collect in the flutes as they cut and are well suited for most applications in shallow cuts. Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction. Applications: Good for 71/ and 625 inco/waspaloy/hastelloy/invar/monel/incoloy, 718 inconel/A286, titanium. Excellent for low carbon/free machining carbon steel, medium to high carbon steel, steel castings and forgings/heat-treatable alloy steels, alloyed tool steels/mold steels, free machining stainless steel, heat and corrosion-resistant stainless steel/valve stainless steel, stainless steel castings/precipitation hardening stainless steel, pure aluminum/aluminum alloys, aluminum alloy castings, grey cast iron, nodular cast iron/chilled cast iron/meehanite iron/ductile iron, pure and alloyed copper, free machining brass/alloyed brass, bronze, zine, magnesium.
