U - Shaped Side Mounted Milling Chuck Bracket, Milling Collet Chuck Holder with Fast Change Joint, Industrial MT3 SLN20 Tool Holder for CNC Milling Machines
High Precision Clamping: This U-shaped side mounted milling chuck bracket delivers 0.005mm accuracy and firm one-time clamping — the inner and outer surfaces are formed simultaneously for maximum contact area with U drills, ensuring zero slippage during high-speed CNC milling operations.
Rapid Tool Changes: The included fast change joint lets you swap tools in seconds without recalibration or realignment — ideal for job shops running multiple part programs where downtime cuts into profitability and precision must be maintained across setups.
Industrial-Grade Durability: Made from hardened high carbon steel and fully quenched, this milling collet chuck holder withstands heavy-duty machining, resists deformation under load, and features an internal coolant outlet hole to extend drill bit life during aggressive .
Superior Surface Integrity: Precision-ground inner bore with surface roughness better than 0.08mm guarantees smooth collet engagement and consistent torque transfer — critical for maintaining dimensional accuracy on tight-tolerance aerospace, automotive, and mold-making parts.
Ready-to-Use CNC Integration: Includes 1 x U-shaped side mounted milling chuck bracket and 1 x fast change joint compatible with MT3 taper and SLN20 collet systems — mounts directly to standard CNC mill heads and fits seamlessly into existing tooling workflows.
