Fits most 13mm drills
1/2in x 20 UNF thread
Opening capacity: 13mm
Durable all metal construction

Installation Info
Most chucks will have a reverse threaded screw locking them in place that will have to be removed before unscrewing and replacing the chuck.

Pro Tip

To seat the chuck firmly on the spindle, run the drill in reverse at low speed for a second after hand-tightening.
If you notice slip on tough materials, retighten at mid-stroke: stop, add a quarter-turn by hand, then continue drilling.

Extra Information

Compatible with drills featuring a 1/2″ × 20 UNF threaded spindle.
Use for rotary drilling (non-hammer) in wood, plastics and light metals.
Keep spindle threads and chuck clean; apply a light oil occasionally.

Features

Keyless mechanism — fast bit swaps without a chuck key.
Self-tightening design — grip increases under load to reduce bit slip.
13 mm capacity — accepts bits from small diameters up to 13 mm.
Thread: 1/2″ × 20 UNF (common drill spindle size).
Hardened jaws & metal body for durability and concentricity.

Benefits

Productivity: change bits quickly between operations.
Secure grip: clamping force resists loosening during use.
Smoother drilling: low run-out helps accuracy and finish.

Safety

Disconnect power or remove battery before changing bits.
Ensure the bit is fully seated and tightened; do not overtighten.
Use in rotary mode; avoid hammer action with add-on chucks.
Wear eye protection and secure the workpiece.
