Precision LBK Extension Rods for BT30/BT40 Spindles – Heavy-Duty Tool Holders with Ultra-Fine Boring Accuracy
Engineered from high-grade alloy steel with hardened precision ground surfaces, these LBK extension rods (LBK1-LBK6) ensure rigid stability and minimal runout (<0.003mm) for high-speed machining. Features BT30/BT40 taper compatibility and RBH/EWN fine boring head integration for deep-hole drilling, milling, and ultra-precision boring in aerospace, automotive, and mold-making. Thermo-symmetrical design eliminates heat distortion, while the anti-vibration grooves enhance surface finish. Ideal for CNC machining centers requiring extended reach without sacrificing accuracy. Includes corrosion-resistant coating for longevity in harsh coolant environments.
