| Core drill with taper shank for enlarging pre-drilled or cast holes in a wide range of materials |
| 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 |
