Countersink tools are used for counter sink operations on holes.
Name — Enter a name that identifies the tool. The name must be unique among all the tools in the crib.
Measure — This indicates the units that are used for reporting the tool’s dimensions. Select Inches for inch units or deselect it for millimeters.
Body Diameter — See diagram.
Flat Diameter — Countersink tools can optionally have a flat end. See diagram.
Shank Diameter — See diagram.
Overall Length — See diagram.
Exposed length — This is the amount of the tool that sticks out of the holder if the holder is simulated.
Angle — See diagram.
Material — This indicates what the tool is made of. This information is important when calculating the feeds and speeds.
Tool Finish — This is the coating, or finish, on the tool. This information is also used in feed/speed calculations. If a feed/speed table exists for a material cut with a tool with a Bright finish, but not for TI_N or Black Oxide tool finishes, then the speed values are derived from the Bright table. The speed for TI_N is 1.5 times the BRIGHT speed. The speed for BLACK_OXIDE is 1.05 times the BRIGHT speed. The feed rates are the same as the BRIGHT feed rates.
Hand — Set whether the tool is Right-handed or Left-handed.
