6-12mm/0.24-0.47" IP54 Digital Three Points Internal Bore Micrometer Set - 3127 Series (Insize)

The Insize 3127 IP54 Digital Three-Point Internal Bore Micrometer Set is designed for precise bore measurements in tight spaces. With a measuring range of 6–12 mm (0.24–0.47 in), it’s ideal for automotive, machining, and quality-control tasks where accuracy and speed matter. The IP54 waterproof design allows reliable use around fluids and coolants, while the digital readout delivers quick, clear results.

Crafted for durability and repeatability, this micrometer uses carbide measuring faces for long life and a built-in ratchet stop to ensure consistent pressure and repeatable results. It offers mm/inch conversion, ABS/INC data formats, and data output when paired with the compatible cable. The kit includes setting rings and extension rods, and it runs on SR44 or LR44 batteries with automatic power-off to conserve energy.

• Three-point internal measuring design: Provides stable contact inside the bore for fast, accurate readings with minimal deviation in small or challenging holes.
• Carbide faces and IP54 protection: Built to resist wear from repeated use and to withstand dust, water spray, and coolants in real-world workshop conditions.
• Versatile kit with accessories and data output option: Includes setting rings and extension rods to reach larger bores (up to 300 mm / 12"), plus an optional data output cable (7302-SPC6) for digital record keeping.

This bore micrometer helps improve measurement reliability and workflow efficiency by delivering clear digital readings, consistent pressure, and adaptable range for a variety of parts and environments. With its durable construction, easy unit switching, and optional data capture, you can trust it to deliver consistent results across jobs while reducing downtime and battery waste thanks to automatic power-off.
