Drilling Calculator

Calculate drill spindle speed, feed rate, thrust force, and torque for through-hole and blind-hole drilling.

Recommended surface speed. HSS in steel: 20-30, Carbide: 80-120 m/min.
m/min
Diameter of the drill bit.
mm
Feed per rev. Steel: 0.15-0.30, Aluminum: 0.20-0.40 mm/rev.
mm/rev
Total depth of the hole to be drilled.
mm
Steel: 2000-2500, Aluminum: 800-1000 N/mm².
N/mm²
