The 1/2 inch hex quick release chuck allows for quick bit changes without the need for a chuck key. Simply insert the bit and turn the collar to tighten or loosen the chuck. This makes changing bits fast and convenient when working in tight spaces.

The chuck has a through hole design which allows it to grip long bits deeper for better retention and less slippage. For improved visibility in dimly lit areas, the DTW190Z has a built-in LED light that illuminates the work area when the trigger is pulled.
