Paint-Fill Engraving: Permanent Tool IDs That Survive Everything

Paint markers flake off metal tools within weeks. Rotary engraving plus paint-fill creates markings that survive solvents, abrasion, and years of abuse. In this episode, we decode engraver spec sheets — why amperage at 12 volts matters more than strokes per minute, where the 1.5-amp cutoff lives for hardened steel, and why battery-powered units deliver inconsistent depth. We also compare rotary engravers to lasers, impact engravers, and metal stamps for marking curved tool surfaces with inventory IDs. If you run a shop, maker space, or home garage with identical-looking sockets and wrenches, this episode will save you time and frustration.
