KUE CNC Oblique Positioning Small Diameter Flat-End Boring Tool 90-Degree Boring Cutter Standard Part ST-MIR 6A60 L15 Bronze
This ST‑MIR small‑aperture flat‑bottom boring tool is built from solid carbide with antique‑bronze coating. It adopts unique oblique‑notch positioning structure for repeated re‑clamping and fast tool setting. It ensures consistent tool position after reinstallation, greatly reducing setup time for Swiss‑type CNC automatic lathe operations.
ST‑MIR 5A60 L25 is a 90‑degree flat‑bottom boring cutter optimized for tiny inner holes. Its special flat‑bottom cutting profile delivers clean flat hole base surface. The coated layer enhances heat resistance and wear resistance, realizing stable precision boring for steel and stainless‑steel small‑size work‑pieces.
Tailored for micro‑hole flat‑bottom boring tasks with limited inner space. Compact tool body works well in narrow small‑diameter cavities. It suppresses cutting vibration during continuous machining, maintains stable dimensional accuracy, and improves efficiency for mass‑production of high‑precision miniature mechanical parts.
