25-50mm/1-2" IP54 Type B Digital Point Micrometer - 3530 Series (Insize)

The 25-50 mm Digital Point Micrometer from Insize, part of the 3530 Series, is a precision measuring tool designed to determine web thickness in drills, narrow grooves, and keyways. With a measuring range of 25–50 mm (1–2 in) and a clear digital readout, it delivers fast, repeatable results for workshop and production settings. It’s ideal for machinists, toolmakers, quality inspectors, and hobbyists who need accurate measurements without guesswork.

Built to endure the demands of everyday machining, this micrometer features IP54 protection, carbide measuring faces, and a reliable ratchet stop for consistent contact pressure. The user-friendly controls provide on/off, set, mm/inch, ABS/INC, and data output, while the LR44 battery powers the display with automatic power-off to save energy. It includes setting standards and supports an optional data output cable for seamless data transfer, with measurement ranges up to 100 mm when used with the data output option.

• High‑Resolution digital readout: Reads to 0.001 mm (0.00005") for quick, precise measurements, reducing guesswork and rework in tight tolerances.
• Rugged, wear‑resistant construction with ratchet stop: Carbide measuring faces and a ratchet mechanism provide durable, repeatable measurements even in busy shop environments, with consistent force applied to the workpiece.
• Easy setup and data capture: Intuitive controls (on/off, set, mm/in, ABS/INC), automatic power off, and an optional data output cable for direct SPC/logging integration; includes calibration setting standards for fast setup.

Using this digital micrometer, you can quickly verify web thickness with confidence, reduce downtime through fast setup and repeatable readings, and streamline QA processes with easy unit switching, data output options, and long-lasting wear resistance. Its rugged IP54 housing and carbide faces mean fewer tool changes and more reliable measurements across drills and keyway applications, helping you achieve precise fits, faster inspections, and improved overall performance in machining and quality control tasks.
