Description

Product Overview

The R0.2 internal boring insert features an ultra-sharp 0.2mm nose radius, specifically designed for small-diameter internal turning and boring operations on Swiss-type CNC lathes. Its compact geometry enables access to tight bores and internal recesses in micro-precision parts. The fine nose radius produces excellent surface finishes and sharp internal corners — critical for dental implant internal connections, watchmaking components, and precision instrument bores.
