Advanced Metrics
How It Works
The countersink depth calculator uses the geometric relationship between the countersink diameter, angle, and depth to determine the missing value.
Formula
Where:
- Diameter: The width of the countersink at the surface
- Angle: The included angle of the countersink tool
- Depth: The vertical depth of the countersink
In advanced mode, you can solve for any missing variable when two of the three values are provided.
Frequently Asked Questions
How to calculate countersink depth?
Countersink depth can be calculated using the formula: depth = (diameter / 2) ÷ tan(angle / 2). Simply input the diameter and angle values into our calculator to get the precise depth measurement.
What units can I use?
Our calculator supports multiple units for diameter (mm, cm, in, ft) and angle (degrees, radians). The depth result will be provided in the same unit as the diameter input.
Can this calculator be used for sheet metal or wood?
Yes, this calculator works for any material where countersinking is applicable, including sheet metal, wood, plastics, and various metals. The calculation is based on geometric principles that apply regardless of material.
What are common countersink angles?
Common countersink angles include 60°, 82°, 90°, 100°, and 120°. The 82° angle is particularly common for flat head screws in many applications.
