DrIll POINT
(NOT AVAILABLE ON MODEL 4086)
The Drill Point function calculates the Drill Point Cut Depth
(length) of the stored Drill Size. By default, the calculation is
based on a Cutting Angle of 118°. If a different Angle is desired,
it can be stored using the Drill Point function (for example,
1 2 0 g D
stores 120°).
Find the Drill Point Cut Depth for a 1/2-Inch drill with a 118°
Cutting Angle. Then, find the Cut Depth using a 127° Angle.
