High Accuracy Mechanical & Digital Inside Micrometers for Bore Hole Internal Measurement

 Roduct Introduction

Two-point inside micrometer is a classic precision measuring instrument specially used to measure inner hole diameter, internal groove width, stepped hole and internal thread minor diameter. Adopting high-precision thread transmission structure, the scale graduation is 0.01mm, complying with ISO international metrology standard and national GB/T 6314 standard.
Made of hardened stainless steel with carbide measuring tips, the measuring face is wear-resistant and anti-corrosion. Knurled anti-slip thimble brings smooth adjustment during operation; built-in locking device can fix the reading value to avoid data deviation after measurement. Multiple measuring ranges are optional from 5–30mm, 25–50mm up to 100–125mm, widely applied in mechanical processing, mold manufacturing and equipment maintenance.

Core Advantages

  • Clear laser engraved scale, long service life without fading

  • Ratchet stop mechanism ensures constant measuring pressure to reduce manual error

  • Compact body, easy to carry and operate without extra power supply
