Drill Chuck Dedra model XDED7707.67 — keyless 1.5–13 mm capacity, 1/2"-20 UNF arbor compatible

Dedra XDED7707.67 is a keyless metal drill chuck with a 1.5–13 mm jaw capacity designed to accept standard twist drills and driver bits. The chuck is compatible with tools that use a 1/2"-20 UNF threaded arbor and provides tool-free, rapid bit changes. Constructed for general drilling tasks in metal, wood and plastic, the chuck is intended for use with portable drills and drill/drivers where a secure grip on round and hex shank bits is required.

Advantages

The keyless design allows quick tightening and loosening of bits without a separate key, reducing downtime during repetitive changes. A full-metal housing and jaws provide durable clamping force and improved wear resistance compared with plastic components. The 1.5–13 mm capacity covers a wide range of common drill sizes used in construction, carpentry and general maintenance, while the 1/2"-20 UNF arbor compatibility ensures fitment to many corded and cordless drill/drivers.

Suitable for

• Portable corded and cordless drills with a 1/2"-20 UNF threaded arbor
• Drilling in metal, wood and plastic using twist drill bits
• Applications requiring frequent bit changes such as assembly and maintenance
• Work requiring a compact chuck that accepts both small and medium drill sizes (1.5–13 mm)

When it may not be suitable

This chuck is not suitable for tools that use a different arbor standard (for example SDS or tapered arbors) or for spindle interfaces that are not 1/2"-20 UNF threaded. For very high-torque industrial applications or heavy-duty hammer drilling, a larger, heavy-duty keyed chuck or a specialized SDS chuck may provide better performance and safety.

Key specifications

• Jaw capacity: 1.5–13 mm
• Type: Keyless metal drill chuck
• Arbor compatibility: 1/2"-20 UNF threaded
• Intended bit types: Round shank twist drills and hex shank driver bits
• Material: Metal housing and jaws

How to use

Ensure the drill is switched off and disconnected from power or battery. Align the drill bit or driver with the chuck jaws, insert the shank fully and hand-tighten the outer sleeve clockwise until the jaws engage the bit. Grip the sleeve and give a firm final twist to secure the bit. To remove the bit, hold the drill steady and rotate the sleeve counterclockwise to release the jaws, then withdraw the bit. Confirm tightness by running the drill at low speed briefly before full-power use.

What to consider before purchase

• Check that your drill accepts a 1/2"-20 UNF threaded arbor before purchase
• Verify the required jaw capacity; 1.5–13 mm covers most common bits but not very large diameters
• Consider whether a keyed chuck or an SDS system is needed for heavy hammering or high-torque work

Usage recommendations

Use the chuck for standard drilling and driving tasks in metal, wood and plastic, keep jaws clean and free of debris, and periodically check tightness during extended work. For repeated high-torque operations, inspect the chuck for wear and replace if gripping performance decreases.
