The Basetech 820708 drill chuck with hex shank is a replacement chuck intended for handheld drills and rotary drivers. It accepts standard straight-shank drill bits and accessories and uses a hexagonal shank to fit directly into compatible quick-change holders or power tool chucks. The design focuses on straightforward bit changes and stable clamping for routine drilling and screwdriving tasks in a workshop or home DIY environment.

Advantages

This drill chuck provides secure three-jaw clamping for a range of bit diameters and a hex shank for fast insertion into compatible tool holders. Its simple construction enables quick manual changes of bits without additional adapters and maintains stable rotation under typical drilling loads. The compact form factor and standard mounting geometry make it suitable as a direct replacement for worn or lost chucks on many handheld drivers.

Suitable for

• General metal, wood and plastic drilling with straight-shank bits
• Quick bit changes on cordless drivers and impact drivers with matching hex holders
• Light to medium workshop and DIY drilling tasks
• Screwdriving where a secure clamp of screwdriver bits is required

Key specifications

• Mount type: hex shank for direct insertion into compatible holders
• Jaw type: three-jaw self-centering chuck
• Compatible bit shank: straight round shanks (sizes depend on chuck capacity)
• Typical applications: drilling and screwdriving in wood, metal and plastic
• Construction: metal body with hardened jaws for clamping durability

How to use

Fit the hex shank of the chuck into the tool holder or driver designed to accept hex shanks, ensuring it seats fully and locks according to the holder's mechanism. Open the jaws by rotating the chuck sleeve, insert the straight-shank drill or screwdriver bit to the required depth, then tighten the jaws by rotating the sleeve in the closing direction until the bit is held firmly. Check that the bit is centered and secure before applying power. For removal, reverse the procedure by loosening the jaws and withdrawing the bit, then slide the chuck out of the holder if replacement or storage is needed.

Recommendations

Use the chuck within its recommended capacity and avoid overloading with oversized bits or excessive torque. For extended life, keep the jaws clean and free of debris, periodically inspect for wear, and avoid using the chuck in applications that subject it to high-impact forces beyond its design. Ensure compatibility with the host tool before use to maintain safe and reliable operation.
