0.3 - 4MM CHUCK

Introducing the 0.3 - 4MM CHUCK, the perfect drill bit clamp for your hobby projects! Our Chuck is designed to work with 0.3mm-4mm drills and uses a JT0 connection rod to connect your motor drills securely

Drill chucks are spindle-mounted mechanisms that hold a drill or other cutting instrument. They come in keyed, keyless, and hybrid systems, allowing rapid drill bit changes. Drill Chucks are frequently linked to a machine's spindle that may be removed through a Drill Chuck Arbor.

Keyed chucks offer the advantage of applying additional torque on the bit when slippage is a concern during heavy-duty applications. When more torque is applied to the bit it makes for a very secure connection which prevents slippage.
