Fafeicy SK40 70 CNC Milling Tool Holder, 20CrMnTi Tool Holder for High Speed Machining ≥12000RPM, Industrial Grade ER Collet with 0.1-0.8in Clamping Range for CNC

High Speed : Engineered for CNC machining at ≥12000RPM with ≤0.05mm accuracy, featuring 20CrMnTi material hardened to 58±2HRC for wear- performance. Versatile Collet: Compatible with 0.1-0.8in tool shanks, ideal for metal/wood milling on CNC lathes and machining centers with quick-change 50mm nut design. Industrial Durability: Vacuum-quenched construction minimizes internal stress, while anti-rust coating protects spindle integrity during heavy-duty operations. Optimized Design: 132mm length with balanced 63mm diameter reduces vibration at high speeds, enhancing operator comfort during prolonged use. Ready-to-Use: Includes one pre-assembled SK40- tool holder (3-20mm clamping range) for immediate CNC machine integration without setup delays.
