## What is CNC Toolkit?

CNC Toolkit brings everyday lathe calculations to machinists, lathe operators and CNC programmers. Enter dimensions alongside a diagram, find tangent points and X/Z coordinates, check tool nose compensation and look up thread dimensions before preparing your program.

• Profile geometry: steps, tapers, chamfers, fillets and grooves, with tangent points and X/Z coordinates.
• Tool nose compensation: calculate compensated coordinates for supported straight, circular and combined profiles.
• Thread reference: metric, UN, Whitworth and common pipe threads, within the ranges stated in each tool.
• Shop calculations: spindle RPM, cutting speed and feed conversions, roughing passes, grooving, parting and drilling depth. Estimate theoretical Ra surface roughness from feed and tool nose radius.
• Material weight: estimate the weight of round bar, tube and rectangular stock from dimensions and material density.
• History and favorites: save dimensions and calculations, then reopen them for another job.

Choose from 95 calculators and reference tools. Supported calculations work in millimeters or inches. Copied results identify their units and coordinate convention. Check results against the drawing, machine and tool setup before machining.

Calculations require Pro, available as a yearly auto-renewing subscription or a lifetime one-time purchase. Prices are shown in the app. The lifetime purchase does not renew.
