About

Practical CNC information, clearly explained

CNC TrueCut is an independent educational website for machinists, operators, students and shop owners. We publish calculators and guides that explain the formulas behind spindle speed, feed rate and common machining decisions.

Our goal is clarity—not replacing a toolmaker’s cutting data or a qualified machinist’s judgment. Always account for your exact material, tool, holder, workholding, machine condition and safety procedures.
