Calculates the spindle speeds of a belt-driven drill press and recommends the optimal belt position for a given drill diameter and material.

Describe your machine once — motor speed, pulley stacks, belts — and the app computes every achievable spindle speed, draws the transmission diagram, and tells you which belt position to use for the hole you are about to drill.

Features:

* Interactive transmission diagram showing the current belt path
* Speed advisor: enter a drill diameter and a material, get the best belt position
* Complete speed table for all belt combinations
* Machine editor with support for multiple machines (create, switch, delete)
* Metric and imperial units
* Interface in English and French
* Fully offline, no permissions, no tracking
