Achieve shop-floor precision with the KATSU Tools Professional Digital Outside Micrometer (SKU: 401330A). Engineered for machinists, engineers, and precision crafters, this premium electronic tool provides extremely accurate thickness and diameter measurements up to 25mm (1 Inch).
Featuring a crystal-clear large LCD display, an advanced data-processing chip for metric/imperial toggling, and robust carbide measuring anvils, it takes the guesswork out of analog vernier reading. It is the perfect tool for automotive repair, tooling engineering, quality control inspection, and industrial DIY projects.
High Resolution & Accuracy: Delivers industrial-grade accuracy down to 0.002mm, with an ultra-fine readout resolution of 0.001mm for absolute measuring confidence.
Dual Measurement Modes: Supports both Absolute (ABS) and Incremental (INC) modes. This allows you to measure the true exact size or quickly check the relative differential value between two different workpieces.
Instant Inch / Metric Conversion: Features a convenient toggle button to instantly switch between Imperial (Inches) and Metric (Millimeters) displays to match any blueprint or technical layout.
Carbide-Tipped Measuring Anvils: The spindle and anvil are hardened, precision-ground, and capped with ultra-hard carbide. This ensures maximum wear resistance and maintains long-term accuracy, even after years of repetitive sliding use.
Large & Clear LCD Display: Eliminates eye strain and manual scale-calculating errors. Read your digital values clearly at a 3-second quick glance.

Zeroing out Before Use: For optimal precision, always clean the carbide measuring faces with a soft cloth and close the micrometer gently to ensure the LCD reads exactly 0.000 (or calibrate via the wrench if necessary) before starting your measurement session.
Use the Ratchet Stop: When clamping onto a workpiece, always rotate via the small end ratchet thimble/stop rather than the large sleeve. The ratchet limits the torque automatically, applying a uniform, consistent force to prevent over-tightening and distorted readings.
Storage Warning: Do not store the micrometer with the two carbide measuring faces directly touching each other locked down tightly. Keep a tiny gap between the anvils during long-term storage in the protective case to prevent thermal expansion pressure.
