Y-MKR 4R0.5 L15 High-Precision Tungsten Steel Groove Cutter Set - MKR Series for Boring & Milling Tools
This Y‑MKR 4R0.5 L15 radius internal grooving tool adopts high‑quality solid tungsten carbide substrate. With reliable copper‑colored hard coating, it owns great hardness and wear resistance, specially designed for small‑diameter internal groove processing for inner holes above 4 mm on Swiss‑type automatic lathes.
Precision‑ground arc cutting edge delivers smooth arc groove profile with high dimensional repeatability. Optimized chip‑breaking geometry ensures stable chip evacuation inside narrow inner holes. It works well on steel and stainless‑steel workpieces and effectively reduces tool chipping and built‑up edge during continuous cutting.
Both forward and reverse cutting versions are available to meet diversified grooving requirements. Compact rigid tool body fits narrow inner‑hole working space. It decreases scrap ratio, extends tool service life, lowers tool‑changing frequency and boosts overall efficiency for mass‑produced miniature precision parts.
