recision Dimensioning for the Professional Workshop The SAMENX Products 3-Piece Spring Caliper Set is an essential dimension transfer kit engineered for machinists, metalworkers, and fabricators who demand rigorous accuracy. Whether you are setting up complex lathe operations, inspecting internal bores, or scribing layout lines, this kit ensures you capture and transfer physical dimensions seamlessly without guesswork. The Complete 3-Piece Kit Includes: 1. Outside Caliper: Designed with smooth inward-curving legs, this tool glides over external surfaces to accurately measure pipe thickness, cylinder OD, and round stock. 2. Inside Caliper: Features outward-facing feet specifically designed for gauging internal cavity widths, bore diameters, and groove spacing. 3. Spring Divider: Equipped with sharp, hardened points for stepping off distances, finding centers, and scribing precise circles onto metal surfaces. Industrial-Grade Construction & Flawless Accuracy Forged from premium carbon steel, the contact points on each tool are hardened to resist wear and maintain their strict calibration in harsh workshop environments. The heavy-duty spring joint mechanism works perfectly with the solid fine-adjustment nut. This guarantees that once you dial in an internal, external, or layout measurement, the tool remains completely rigid. Transfer your measurements directly to a stainless steel scale or micrometer with absolute confidence—zero slipping, shifting, or loss of dimension. Ideal for CNC machine setups, automotive mechanics, pipe fitting, and professional metal fabrication.
