drill point cone length calculator online

Use drill point cone length online for diameter mm, point angle deg. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.

How to use it

Enter diameter mm. Set point angle deg. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
diameter mmMain input. Positive values. 10
point angle degOption. Signed finite values. 118

Calculation method

point_length_mm = diameter_mm/(2*tand(range(point_angle_deg,1,179)/2)) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply drill point cone length to the case below, keeping the displayed units and assumptions. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.

Choose the right tool

Use cutting data suitable for the actual tool and material. Effective diameter, engagement and chip thickness affect the applicable formulas. Cycle estimates do not generate machine-ready instructions or validate safe operation.

Limitations and common mistakes

  • Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
