40 — Machinist calc™ ProDrIll POINTThe Drill Point function calculates the Drill Point Cut Depth(length) of the stored Drill Size. By default, the calculation isbased on a Cutting Angle of 118°. If a different Angle is desired,it can be stored using the Drill Point function (for example,120gD stores 120°).Find the Drill Point Cut Depth for a 1/2" drill with a 118° CuttingAngle. Then, find the Cut Depth using a 127° Angle.KeySTROKe DISPLAyOO 0.1. Enter the Drill Size:1/2D 1/2 DRILL SIZe $ 0.5000 INCH2.

Upon entering the Thread Size, the Threadsper Inch (TPI) or Pitch is required. If the entered Thread Sizeis a standard size, continuous presses of the t key willtoggle through the available common TPI or Pitches. Once thedesired TPI/Pitch is reached, pressing O stores the Thread
