KEUE CNC Tungsten Steel MNR 6R0.2 L22 Boring Tool Carbide/Tungsten Steel Wear-resistant Impact-resistant Special Steel Small
This MNR 6R0.2 L22 small‑hole rough boring cutter is made of high‑strength solid tungsten carbide. Optimized for steel and stainless‑steel rough machining, it delivers excellent rigidity and impact resistance, perfectly matching the working demands of Swiss‑type automatic lathes for micro‑hole processing.
Professionally ground rough‑machining edge handles heavy‑load cutting tasks steadily. The high‑performance coating greatly improves wear resistance and suppresses built‑up edge. It realizes reliable chip evacuation inside narrow inner holes and keeps stable dimensional performance in continuous rough‑boring work.
This tool belongs to the mature MNR‑SBFR series with rich available specifications. Its compact rigid body adapts to limited inner‑hole space, lowers risk of tool breakage, extends service life, reduces frequent tool replacement and lifts overall efficiency for mass‑produced miniature parts.
