Description
Three-Point Internal Micrometer 20-25mm for Cylinder Bore Measurement
Key Features
  • Three-point micrometer centering self and aligning self.
  • Measurement can be taken closer to the bottom of blind bores and deep holes with extension rod.
  • Carbide-tipped contacts points with ratchet stop.
  • Supplied with setting rings and fitted case.
Product Description

This three-point internal micrometer series offers measuring ranges from 6-8mm up to 40-50mm, with graduations of 0.001mm

(within 12mm/0.5") or 0.005mm (over 12mm). The carbide-tipped three contact points minimize measurement errors, significantly improving

accuracy compared to calipers.

The self-centering three-point contact design ensures precise bore measurements, particularly effective for blind and through holes.

The micrometer automatically centers and aligns itself for stable, accurate readings.

Complete sets are available covering wide measurement ranges for various industrial applications.
