YG-1 I9 Series Vanadium Alloy HSS Spiral Pointed Tap, Steam Oxide, Round Shank with Square End, Plug Chamfer, 5/16"-18 Thread Size, H3 Tolerance

YG-1 I9 series vanadium alloy HSS spiral pointed tap. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. 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 steel castings and forgings/heat-treatable alloy steels, free machining stainless steel, heat and corrosion-resistant stainless steel/valve stainless steel, aluminum alloy castings, nodular cast iron/chilled cast iron/meehanite iron/ductile iron. Excellent for low carbon/free machining carbon steel, medium to high carbon steel.
