Counterbore

Counterbore tools are used for the counterbore operations of counter bored 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.

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.

Shank Diameter — See diagram.

Pilot Diameter — See diagram.

Pilot Length — See diagram.

Flutes — Enter the number of grooves on the tool.

Touch off at the shoulder — Select this check box to position the tool z-zero at the end of the flutes (the tool shoulder). Deselect the check box to position the tool z-zero at the end of the pilot (the tool tip).

Tool 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.
