Precision-Machined BT50-BST YBH200-310 Micro Fine Boring Head Set for High-Accuracy Machining

Engineered with hardened alloy steel and ultra-fine micrometer adjustment (0.001mm precision) for flawless surface finishes in CNC milling. Features dual-contact BT50 taper for superior rigidity, reducing vibration during heavy-duty rough boring.

Integrated modular design allows quick tool changes between roughing and finishing. Includes balanced boring bars (200-310mm range) for deep-hole drilling in automotive cylinder blocks or aerospace components.

Diamond-coated inserts (included) extend tool life by 3X vs standard carbide. Compatible with BT40/BT50 spindles—ideal for vertical machining centers in high-volume production lines.

Priced for bulk OEM/wholesale buyers—direct factory sourcing eliminates middlemen markup. Ships globally with ISO9001-certified quality assurance.
