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

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

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)

atan

Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle.

Syntax: atan(Number)
