About this app

Made for a clear purpose.

Chipwright: Machinist Suite is a polished offline calculation and reference desk for milling, turning, threading, fitting, and everyday shop math.

FROM SETUP TO INSPECTION - Calculate spindle speed, feed rate, chip load, and material-removal rate - Account for radial chip thinning and configurable tool geometry - Work through common inch and metric thread dimensions - Calculate three-wire and over-pin measurements - Explore ISO 286 hole and shaft fits with a live tolerance visualization - Solve bolt circles, tapers, sine-bar setups, and right triangles - Search drill, tap, ream, G-code, M-code, and GD&T references - Save a local tool library and export shop notes

ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated service - Calculators and reference content work offline - No device permissions are required - Tool and shop data remain on the device unless you deliberately export them

Shop-planning reference only. Verify tooling limits, workholding, material condition, machine capability, coolant, tolerances, controller behavior, and safety procedures before cutting material.
