What Is Drill Tip Length?

The length of the drill tip is the distance from the end of the drill to where the flutes begin to form. This dimension is handy for the user to conduct a very accurate drilling exercise, such that one can confirm whether the right drill bit is used.

User Guide

To use the Drill Tip Length Calculator is simple:

  1. Enter Drill Diameter: Input the diameter of the drill in inches.
  2. Enter Tip Angle: Input the tip angle in degrees.
  3. Calculate: The calculator will provide the drill tip length in inches.

Example:

  • Drill Diameter: 0.5 inches
  • Tip Angle: 118 degrees

Formula

To calculate the drill tip length, use the following formula:

DTL=D2×tan(A2)\text{DTL} = \frac{D}{2 \times \tan\left(\frac{A}{2}\right)}

Variables:

Variable Description
DTL Drill Tip Length (in)
D Drill Diameter (in)
A Tip Angle (degrees)

How to Calculate Drill Tip Length

1. Convert Angle to Radians:

First, convert the tip angle from degrees to radians.

Radians=A2×57.2958\text{Radians} = \frac{A}{2 \times 57.2958}

2. Calculate Tangent: Find the tangent of the angle in radians.

tan(Radians)\tan(\text{Radians})

3. Divide Diameter by Tangent: Divide the diameter by the tangent value to get the drill tip length.

DTL=D2×tan(Radians)\text{DTL} = \frac{D}{2 \times \tan(\text{Radians})}

Example Calculation:

Step 1: Convert 118 degrees to radians:

Radians=1182×57.2958=1.03 radians\text{Radians} = \frac{118}{2 \times 57.2958} = 1.03 \text{ radians}

Step 2: Calculate the tangent of 1.03 radians:

tan(1.03)=1.73\tan(1.03) = 1.73

Step 3: Calculate the drill tip length:

DTL=0.52×1.73=0.144 inches\text{DTL} = \frac{0.5}{2 \times 1.73} = 0.144 \text{ inches}

FAQs

What is the drill tip length?

Drill tip length is the distance from the drill tip to where flutes start forming.

How does the tip angle affect the length of the drill tip?

If a drill has a larger tip angle, its tip length will be shorter. On the other hand, a smaller tip angle creates a longer one.

Can this calculator be used for any size of drill bit?

Yes, the Drill Tip Length Calculator can be used for any size of drill bit, provided that you know the diameter and tip angle.
