Drill Tip Length Formula:
From: | To: |
Drill tip compensation calculates the additional length needed to account for the pointed tip of a drill bit. This is important for precise depth measurements in machining and drilling operations.
The calculator uses the drill tip length formula:
Where:
Explanation: The formula calculates the length of the conical tip based on the drill's geometry, which must be added to the desired hole depth for accurate drilling.
Details: Accurate tip length calculation ensures precise hole depths, especially critical in CNC machining, aerospace components, and other precision engineering applications.
Tips: Enter the drill diameter in millimeters and the point angle in degrees (typically 118° or 135° for standard drills). Both values must be positive numbers.
Q1: What's a typical drill point angle?
A: Standard twist drills typically have 118° or 135° point angles. Specialty drills may have different angles.
Q2: Why is tip compensation important?
A: Without compensation, holes will be shallower than intended by the length of the drill's tip.
Q3: Does this work for all drill types?
A: This calculation works for conical point drills. Special tip shapes may require different calculations.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise for perfect conical tips. Actual drill tips may vary slightly.
Q5: Should I round the result?
A: Round to 2-3 decimal places (0.01-0.001 mm) for most practical applications.
