Description
The Insize 3127 IP65 Digital Three Point Internal Bore Micrometer covers bores from 175 to 200 mm (6.89–7.87") with a precise, digital readout. Built for reliability in busy workshops, manufacturing floors, and field service, it delivers quick, repeatable measurements in demanding environments.
With carbide measuring points and IP65 protection, this micrometer stands up to dust, moisture, and tough shop conditions while maintaining accurate readings. Its automatic power-off and ratchet stop help you work efficiently, so you can focus on getting consistent results every time.
- IP65 protection with carbide measuring points: Dustproof and waterproof housing combined with wear‑resistant carbide tips means longer tool life and dependable performance in harsh environments.
- Digital three-point bore measurement with high resolution: Three-point contact reduces bore taper error, while the digital display provides fast, repeatable readings at 0.001 mm (0.00005") with 7 μm accuracy.
- User-friendly operation and data connectivity: Intuitive controls (on/off, set, mm/inch, data transmit) with data output and automatic power-off; ratchet stop ensures consistent force. Includes manufacturer inspection certificate and optional accessories.
This bore micrometer helps you speed up QC and assembly work, delivering reliable inside-diameter measurements with clear documentation. The combination of rugged protection, durable carbide tips, and a precise digital readout translates into fewer rechecks, smoother workflows, and repeatable results you can trust across multiple jobs.
