Drilling power calculator

Estimate drilling spindle speed, feed rate, material removal rate and approximate cutting power.

Estimate drilling feed, material-removal rate and cutting power.

Estimated drilling load0.23 kW cutting power

796 RPM · 95.5 mm/min feed · MRR 7500 mm³/min

Approximate cutting-power estimate. kc is an input, never a hard-coded value. Sandvik kc1 ranges (N/mm²): steel P 1500-3100, stainless M 1800-2850, cast iron K 790-1350, aluminium N 350-1350, hardened H 2550-4870 — a roughly 2x spread within a group, so use the tool/maker value for your material. Machine efficiency, drill geometry, material condition and chip evacuation affect the actual load.

Built for practical decisions

This expert estimate links drilling geometry and specific cutting force to machine load. Drill design, workholding, material condition, coolant and machine efficiency affect the real requirement.

Important assumptions

Use the result as a planning estimate. Confirm material data, machine settings, drawing tolerances and applicable standards before production or structural work.

Quick answers about this drilling power calculator

What does the drilling power calculator help me decide?

Estimate drilling spindle speed, feed rate, material removal rate and approximate cutting power.

Can I use the result directly for production?

Use it as a starting estimate. Verify the drawing, material grade, machine capability, tooling data and applicable standard before cutting, forming, welding or ordering material.
