Precision CNC Micro Boring Bars – Solid Carbide Tool for Ultra-Fine Machining
Ultra-fine solid carbide construction ensures exceptional rigidity and wear resistance for high-speed, high-precision boring. Micro-diameter design (MTR/MFR/MPR/MUR/MQR/MGR/MKR series) caters to intricate internal turning in tight spaces. Mirror-polished cutting edges minimize friction, delivering superior surface finishes for aerospace, medical instruments, and watchmaking. Heat-resistant coating extends tool life by 300% compared to standard HSS, ideal for hardened steels and superalloys. Interchangeable tip system allows quick adaptation for blind holes, deep bores, and tapered machining without recalibration. Full metric and imperial sizing compatibility with Swiss-type lathes and CNC micromachining centers. Direct factory pricing – bulk orders receive additional discounts with guaranteed global shipping.
