RRP: over $600

This Mitutoyo 345-250-30 Digital Blade Micrometer is a high-precision measuring instrument engineered for external measurements in narrow and recessed areas. With a measurement range of 5mm to 30mm, and blade-shaped measuring faces (0.75mm thick), it’s perfect for groove and keyway inspection where standard micrometers can’t reach.

Made in Japan and lightly used, this micrometer delivers trusted Mitutoyo accuracy (±4 µm) and repeatability with a resolution of 0.001mm. It features an easy-to-read LCD display, zero-set, hold, and data output via SPC for streamlined digital measurement logging. Carbide-tipped blades ensure long life and consistent performance—even in demanding workshop environments.

This model meets or exceeds IP65 standards for coolant and dust resistance, making it a reliable choice for high-precision measurement in both shop-floor and lab settings.

Whether you’re a machinist, metrologist, or quality control technician, this Japanese precision tool is ideal for fine tolerance inspection work in milling, turning, and grinding applications.
