Divide half the diameter of the countersink by the tangent of half the angle to find the countersink depth.
The Countersink Depth Calculator is a valuable tool for precision machining and woodworking. It helps determine the accurate depth of a countersink based on the hole diameter and the included angle. This ensures proper fit for screws and bolts, preventing damage and promoting a clean, professional finish.
Formula
CD = (D / 2) / tan(A / 2)
| Variable | Definition |
|---|---|
| CD | Countersink Depth |
| D | Diameter of the Countersink (inches or mm) |
| A | Included Angle of the Countersink (degrees) |
Solved Calculations
Example 1: Determine the depth of an 82° countersink with a 0.5-inch diameter.
| Variable | Value |
|---|---|
| Diameter (D) | 0.5 inches |
| Angle (A) | 82 degrees |
| Countersink Depth (CD) | 0.176 inches |
Example 2: Find the depth of a 100° countersink with a 1.0-inch diameter.
| Variable | Value |
|---|---|
| Diameter (D) | 1.0 inches |
| Angle (A) | 100 degrees |
| Countersink Depth (CD) | 0.289 inches |
What is Countersink Depth Calculator?
The Countersink Depth Calculator is a precise tool used to determine the depth of a countersink hole, ensuring accurate and consistent results for machining, woodworking, or metalworking projects.
It simplifies calculations based on inputs like diameter, chamfer angles, and screw specifications, saving time and improving accuracy.
This calculator is particularly helpful for determining values such as the countersink diameter, chamfer depth, and countersink depth from diameter.
It aids in creating holes that perfectly fit screws, bolts, or rivets by referring to standards like the 82-degree countersink depth chart or 100-degree countersink chart.
Additionally, you can utilize it for specialized tasks such as calculating depths for center drill holes or 45-degree chamfers.
Professionals often use this tool alongside countersink feed and speed calculators to optimize machining processes.
Whether working on metals, plastics, or wood, the calculator ensures precision by measuring parameters like countersink angle, depth-to-diameter ratios, or even converting between metric and imperial units.
Final Words:
In summary, the Countersink Depth Calculator is an indispensable resource for achieving accurate countersink measurements. By automating complex calculations, it enhances productivity, precision, and consistency in a variety of applications.
