Milwaukee's 1/2 in. Keyless Service Chuck w/Carbide Tip is a genuine OEM replacement part professionally engineered to provide superior bit retention for high-performance drilling and driving.

Its specialized ratcheting mechanism provides an audible click when the jaws are fully tightened, ensuring your accessories are securely locked for high-vibration tasks such as hammer drilling.
Key Features
Carbide-Tipped Jaws provide an industrial-strength grip on drill bits, resisting wear and ensuring long-term reliability even when using smooth-shank accessories.
Heavy-Duty All-Metal Design is built to withstand the extreme torque and impact forces typical of professional 18V and 28V cordless power tools.
1/2" - 20 UNF Mounting utilizes a left-handed thread for secure attachment to the drill spindle, preventing the chuck from spinning off during reverse operations.
Quick-Change Keyless Action allows for fast, one-handed bit swaps without the need for a chuck key, increasing productivity on the jobsite.
Audible Ratcheting Lock confirms the bit is securely fastened and prevents the jaws from loosening during aggressive hammer-drilling cycles.
Broad Model Compatibility serves as the factory-standard replacement for a wide range of legacy M18™ and 28V tools, including the 0726-20 and 2611-20 models.
Inclusive Service Hardware often comes with the necessary mounting screws (05-88-1500 and 06-82-2025) to facilitate a complete and secure installation.
Genuine Milwaukee Quality ensures original factory specifications for balance, runout, and safety are maintained after a repair.
