*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
*Morse taper shank allows the tool to be inserted directly into the machine's spindle to facilitate high-torque applications such as large cut diameters
*When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
*Designed to perform in a broad range of materials in the iron and steel families
