1. What is Drill Tip Compensation?

Drill tip compensation accounts for the conical shape at the end of a drill bit when calculating precise drilling depths. The tip length must be added to the desired hole depth to achieve accurate results.

2. How Does the Calculator Work?

The calculator uses the drill tip length formula:

Where:

• \( Diameter \) — Drill bit diameter (inches)
• \( Angle \) — Included angle of drill point (degrees)
• \( \tan \) — Tangent trigonometric function

Explanation: The formula calculates the length of the conical tip based on the drill's geometry.

3. Importance of Tip Length Calculation

Details: Accurate tip length calculation is crucial for precision drilling operations where exact hole depths are required, especially in CNC machining and aerospace applications.

4. Using the Calculator

Tips: Enter drill diameter in inches and point angle in degrees. Both values must be positive numbers (angle typically between 90-140 degrees for standard drills).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical drill point angle?
A: Common angles are 118° (general purpose), 135° (harder materials), and 90° (soft materials).

Q2: Why is tip compensation important?
A: Without compensation, holes will be shallower than intended by the length of the drill tip.

Q3: Does this work for all drill types?
A: This applies to standard conical point drills. Special drills (like center drills) may need different calculations.

Q4: How precise should my measurements be?
A: For critical applications, measure diameter to 0.001" and use the exact angle specified for your drill bit.

Q5: Can I use this for metric measurements?
A: Yes, but convert all units consistently (use mm for both diameter and tip length).
