CNC Milling Chucks

Precision‑ground to ISO AT3 taper tolerances with runout under 0.005 mm and surface roundness Rz 2.5—our CNC Collet Chuck Milling Holders are built to secure end mills with exceptional accuracy and balance (standard G6.3 up to ~8,000 rpm, with higher-balanced options available). They’re ideal for high‑precision milling, reducing vibration and extending cutter life.

Why Choose Our CNC Collet Chuck Milling Holders?

• High Accuracy. Steep-taper holders ground to AT3 (or better) deliver reliable concentricity—most exceed AT3 standards for tight spindle engagement.
• Minimal Runout. Achieve tool alignment within 0.005 mm to protect tool life and surface finish on high-speed milling operations.
• Broad Compatibility. Available in BT30/40/50, CAT40/50, SK40/50, DIN2080 (30/40/50), NT (30/40/50), and HSK interfaces—supporting ER11 through ER40 collet types and multiple length configurations.
• Stable Balance. Standard G6.3 balance at speeds up to 8,000 rpm ensures smooth performance; higher‑grade balancing available for faster spindle setups.
