Three Point Internal Micrometer Set Includes Calibration Ring & Accessories
Quick 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 rods.
- Carbide-tipped contact points with ratchet stop.
- Includes setting rings.
- Comes in a fitted case.
Product Description
This three-point internal micrometer set offers measuring ranges from 6-8mm up to 87-100mm with graduations of 0.001mm (for measurements under 12mm) and 0.005mm (for measurements over 12mm). The set includes setting rings and features carbide-tipped three-point contacts that minimize measurement errors and improve accuracy.
The self-centering three-point contact design ensures precise bore measurements, providing significantly more accurate results than calipers. This structure maintains stability when measuring both blind and through holes. We offer sets with various measuring ranges to suit different applications.
