Precision-Machined BT40/BT50-BST Boring Tool Holder for CNC Excellence

High-grade alloy steel construction ensures maximum rigidity and vibration damping during heavy-duty machining. Hardened to HRC 45-50 with ground taper surfaces (0.001mm tolerance) for perfect spindle alignment.

Optimized internal coolant channels reduce heat buildup when drilling deep cavities in aerospace alloys or automotive molds. Dual contact design (face + taper) boosts stability for finishing hardened steels above HRC 60.

Interchangeable between BT40 and BT50 spindles using adapter sleeves – ideal for job shops running mixed machine types. Pre-balanced to 15,000 RPM minimizes harmonic chatter in aluminum high-speed milling.

Backed by 12-month warranty against material defects. Bulk pricing available for factory procurement teams. Ships in anti-corrosion VCI packaging with inspection certificate.
