KEUE CNC Solid Carbide Sbqr4 10L R0.1 Machining Tool Stainless Steel Boring Centering Machine Small Hole Chamfering Profile
The SBQR series small‑hole boring tool is made of solid tungsten carbide with high‑aluminum nano‑coating. It is specially built for Swiss‑type lathes, supporting profiling and reverse chamfering, and works well for steel and stainless steel materials up to HRC40 hardness range.
Optimized 52‑degree tool angle and fine‑ground cutting edge deliver stable performance for confined inner‑hole operations. The premium nano‑coating lowers friction and resists wear, reducing built‑up edge to maintain smooth surface finish and consistent dimensional precision.
Multiple standard sizes cover different bore diameters, and custom non‑standard dimensions are available upon request. Its compact rigid structure fits narrow inner‑hole space perfectly, extends tool life, reduces replacement frequency and improves batch‑processing productivity for miniature parts.
