The Marksman Keyless Chunk is the vital connection between your power tool and your drill bit. Specifically designed for users who need to switch frequently between drilling and driving, this chunk removes the frustration of lost keys. It is a professional-grade replacement for worn-out factory parts, helping to restore the precision and gripping power of your drill.
In a busy workshop, every second counts. The keyless design of this chunk allows you to open and close the jaws with a simple twist of the outer sleeve. Whether you are moving from a small pilot bit to a large spade bit, the internal mechanism provides a self-centering grip that keeps your bit perfectly aligned, preventing “wobble” and ensuring clean, professional results.
Despite its ease of use, the Marksman chunk is built for toughness. It is manufactured from impact-resistant materials that can handle the vibration and heat generated during heavy masonry or metalwork. The three-jaw system is engineered to distribute pressure evenly around the bit shank, significantly reducing the risk of slippage even when under high load.
