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.
