HARKY F4 Series Vanadium Alloy HSS Spiral Flute Tap, Steam Oxide, Round Shank with Square End, Bottoming Chamfer, 5/16"-18 Thread Size, H3 Tolerance
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
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
