KEUE CNC Carbide Micro-Diameter Boring Tool for Automatic Lathe Small Inner Hole Turning Rod
These KT30‑SBTR and KT40‑SBTR small‑bore boring cutters are constructed from solid tungsten carbide base. Equipped with premium thin‑gold coating, they bring excellent surface hardness and heat resistance, perfectly designed for fine finishing of stainless steel and other hard‑to‑cut materials on Swiss‑type CNC lathes.
Optimized anti‑vibration tool‑body structure effectively suppresses chattering during micro‑hole finishing. Precisely ground R0.2 cutting edge delivers brilliant high‑gloss surface quality. It reduces built‑up edge risk, ensures smooth chip flow inside narrow bores and maintains stable machining accuracy for long‑run production.
Available in multiple sizes to satisfy diverse small‑aperture finishing requirements. Compact rigid tool profile fits limited inner‑hole working space well. It lowers scrap rate, extends tool service life, cuts tool‑changing frequency and greatly improves comprehensive processing efficiency for miniature precision component mass production.
