Integral Drill Chuck, Straight Taper, APU16 - for CNC Milling

【Self-Locking Mechanism】The self-locking mechanism of this self-tightening wrench increases holding force during use, preventing tool slippage and maintaining concentricity under high torque loads.
【40C Steel Body】Made of hardened 40Cr steel, this body resists wear and deformation during repeated heavy-duty cycles, thanks to a special heat treatment that provides optimal hardness.
【Compact Integrated Shank】The straight shank, forged as a single piece with the chuck body, eliminates any runout and offers a slim profile for accessing tight machine spindle spaces.
【1-13mm Range】This chuck accepts drill bits and tools with shank diameters from 1mm to 13mm, providing the versatility needed for operations ranging from fine drilling to large reaming diameter.
【Mounting Security】The APU16- interface is designed to lock firmly onto the machine taper, preventing any dislodging or wobbling of the chuck during high-speed milling or drilling.
