About this item
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
For general purpose drilling in applications where extra length for reach is required, designed to perform in a broad range of materials in the iron and steel families
