KEUE CNC Small Diameter Internal Boring Tool KT30-SBPR3 6L R0.1 TiAlN Carbide HRC 91-93.5 for CNC Lathe
This KT30‑SBPR3 6L R0.1 small‑bore boring tool is made of solid tungsten carbide with ultra‑thin titanium nitride coating. Optimized geometric structure fits small‑diameter inner hole machining, perfectly matched for Swiss‑type and CNC lathe micro‑boring applications.
The titanium nitride coating delivers bright surface finishing under low‑speed cutting conditions. Precision ground R0.1 tip radius ensures stable cutting performance, producing smooth inner‑hole surface and keeping consistent dimensional accuracy for steel and stainless‑steel workpieces.
Compact tool body is designed for narrow inner‑hole space, enabling reliable boring within limited machining depth. It maintains stable performance in continuous‑batch production, reduces tool wear and replacement frequency, improving overall workshop processing efficiency.
