Tungsten Steel MNR 6R0.2 L22 Small Hole Boring Cutter Wear-Resistant Impact-Resistant for Stainless Steel Processing
This MNR 6R0.2 L22 small‑hole rough boring cutter is made of high‑strength solid tungsten carbide. It supports both right‑hand and left‑hand styles, specially developed for rough boring of inner holes above 1 mm, widely compatible with Swiss‑type CNC lathes for steel and stainless‑steel workpieces.
Optimized cutting geometry delivers outstanding shock resistance and anti‑wear performance for rough‑cut scenarios. The premium coated surface improves heat dissipation, effectively resisting chipping, maintaining stable cutting state and reliable dimensional repeatability under heavy‑load rough boring conditions.
Compact slim tool shank fits narrow inner‑hole machining space perfectly. It reduces tool breakage risks during rough machining, extends tool service life, lowers frequent tool replacement costs, and greatly raises processing efficiency for mass‑production small‑part workshops.
