Drill Press Assistant0.1.0

Enter a drill diameter and workpiece material to receive a recommended belt position for the hole you are about to drill. Drill Press Assistant calculates the spindle speeds available from a belt-driven drill press and helps replace manual pulley-ratio calculations with a direct workshop reference.

First describe each machine by entering its motor speed, pulley stacks, and belts. The app then calculates every achievable spindle speed, presents the combinations in a complete speed table, and displays the transmission as an interactive diagram with the current belt path. Multiple machine profiles can be created, selected, and deleted, while metric and imperial units accommodate different workshop conventions.

It suits machinists, makers, students, and maintenance users who adjust belt-driven drill presses for different hole sizes and materials. The interface is available in English and French, and its native Android implementation uses Kotlin and Jetpack Compose; the calculation core is shared in behavior with the web edition. It runs fully offline, uses no permissions, and includes no tracking, which is useful at a machine where connectivity is limited.

Drill Press Assistant 0.1.0 runs on Android 8.0 or later for arm64-v8a, armeabi-v7a, x86_64, and x86 devices. It is open-source and belongs to the Education category. Building the native project requires JDK 17 or newer together with Android SDK Platform 35 and Build-Tools 35.
