Diameter of Drill Bit given Length of Approach Solution

Follow our step by step solution on how to calculate Diameter of Drill Bit given Length of Approach?

FIRST Step Consider the formula

D = 2 \cdot \frac{A}{\tan (\frac{π}{2} - \frac{θ}{2})}

Next Step Substitute values of Variables

∴

D = 2 \cdot \frac{12.5mm}{\tan (\frac{π}{2} - \frac{135°}{2})}

Next Step Substitute values of Constants

∴

D = 2 \cdot \frac{12.5mm}{\tan (\frac{3.1416}{2} - \frac{135°}{2})}

Next Step Convert Units

∴

D = 2 \cdot \frac{0.0125m}{\tan (\frac{3.1416}{2} - \frac{2.3562rad}{2})}

Next Step Prepare to Evaluate

∴

D = 2 \cdot \frac{0.0125}{\tan (\frac{3.1416}{2} - \frac{2.3562}{2})}

Next Step Evaluate

∴

D = 0.0603553390592894m

Next Step Convert to Output's Unit

∴

D = 60.3553390592894mm

LAST Step Rounding Answer

∴

D = 60.3553mm

Diameter of Drill Bit

Diameter of drill bit is essentially the straight distance across the widest part of the cutting edge (lips) of the drill bit. It determines the width of the hole it will create on workpiece.

Symbol: D

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Diameter of Drill Bit

Approach Distance

Approach Distance is the extra distance the drill travels before it starts cutting into the workpiece. It allows the tool to reach its cutting speed and position itself properly for an accurate hole.

Symbol: A

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Approach Distance

Drill Point Angle

Drill Point Angle is the angle between the two cutting edges (lips) of a drill bit at its tip. This angle affects how aggressively the bit cuts and what materials it's suited for.

Symbol: θ

Measurement: AngleUnit: °

Note: Value should be greater than 0.

Formulas to find Drill Point Angle

Archimedes' constant

Archimedes' constant is a mathematical constant that represents the ratio of the circumference of a circle to its diameter.

Symbol: π

Value: 3.14159265358979323846264338327950288

tan

The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle.

Syntax: tan(Angle)
