Description
Stop guessing your plunge depth. Get precise Z-axis coordinates instantly.
CNC Countersink Calculator is a clean, professional, and reliable machinist tool designed specifically for CNC programmers, setup operators, manual machinists, and lathe operators. Whether you are running a high-speed machining center or a manual mill in a local machine shop, this engineering utility helps you calculate the exact depth of cut required for any countersink or chamfer.
Unlike basic calculators, this application features a dynamic 2D visual blueprint chart that morphs in real-time as you enter your geometry. It visually highlights your target dimensions and shows you exactly how the tool engages the workpiece.
NEW in v1.1.0: - Built-in Reference Guide with engineering diagrams (tap ℹ in header) - Help tooltips (?) on key input fields for beginners and new operators - Fixed flat tip formula for accurate worn-tool calculations - Input validation preventing negative plunge depth on oversized tip flats
Why Choose This Machinist Calculator? In manufacturing, a mistake by a few thousandths of an inch can scrap an expensive part. This engineering tool eliminates manual trigonometry formulas, prevent errors, and saves valuable cycle time at the machine controller.
Key Features & Capabilities: Real-Time 2D Visual Chart: A dynamic engineering drawing (CustomPainter layout) that reflects changes in dimensions instantly, visualizing the exact triangle of the chamfer and highlighting the Z-depth with precise measurement lines.
Sharp & Flat Tip Tool Support: Our unique algorithm handles standard sharp countersinks as well as flat-tip (worn or specific geometry) tools. See the virtual tool tip projected in a dashed line on the blueprint!
Standard Preset Tool Angles: Quick toggles for the most common manufacturing and aerospace angles: 60°, 82°, 90°, and 120°.
Custom Angle Input: Working with a special chamfer mill or custom tool? Easily input any custom angle from 1° to 179°.
Instant Unit Conversion (Imperial / Metric): Toggle seamlessly between Inches (in) for US shops and Millimeters (mm) for global metric standards. Data converts instantly without clearing your inputs.
One-Tap Reset Feature: Instantly clear all fields and restore default parameters with a single button to quickly start measuring the next part.
Perfect for the Machine Shop Environment: Designed with a dark, high-contrast UI tailored for low-light shop floors and CNC control stations.
Large, tactile, operator-friendly numeric input fields designed to minimize typing mistakes.
Lightweight, completely offline app that doesn't require an internet connection to run inside a shielded factory.
How to Calculate Countersink Depth in 3 Steps: Select or input your Tool Angle (α) and optional Tip Flat (t) dimension.
Enter the Hole Diameter (d) of the pre-drilled feature.
Input your desired Target Diameter (D) of the final chamfer.
The app instantly displays the required Plunge Depth (Z) using precise mathematical formulas rounded to standard manufacturing tolerances (4 decimal places for inches, 3 for millimeters).

Recent changes: v1.2.0 Banner ad added to support free app development. Adaptive banner scales to any screen width. Bug fix: flat tip formula corrected Z = (D − t) / (2 × tan α/2). Validation: tip flat cannot exceed target diameter. Reference Guide with engineering diagrams (tap ℹ). Help tooltips (?) on key input fields.
