Extension for drill bits Irwin Quick Change 1/4" 65 mm model 10508166

Irwin Quick Change 1/4" 65 mm extension for drill and screwdriver bits provides a compact, easy-to-use solution for gaining extra reach when working in confined or recessed spaces. The tool accepts standard 1/4" hex shank bits and is compatible with Quick Change bit holder systems, enabling fast bit swaps and secure retention during use. With a 65 mm overall length, this extension balances reach and control for assembly, repair and installation tasks where direct access with a standard driver is limited.

Advantages

The extension is constructed to fit standard 1/4" hex shank bits and to work with quick-change systems, reducing downtime during bit changes. Its 65 mm length offers additional reach without significantly affecting tool balance or handling. Designed for compatibility with impact drivers and drills that accept quick-change holders, the extension maintains a firm grip on bits under torque and in demanding fastening operations.

Suitable for

• Fastening screws in recessed or narrow openings
• Accessing hard-to-reach screws during assembly or repair
• Installation tasks where extra reach is required without switching to longer tools
• Use with impact drivers and drills that support Quick Change bit holders

Key specifications

• Bit shank type: 1/4" hex
• Overall length: 65 mm
• Compatibility: Quick Change bit holder systems
• Intended use: drill and screwdriver bits extension for fastening and drilling access

How to use

Insert a compatible 1/4" hex shank bit into the extension until it locks in the quick-change mechanism, then insert the extension into the drill or impact driver chuck or quick-change holder. Ensure the bit is seated firmly before applying torque. Use steady pressure and appropriate speed for the screw or material being worked on. Remove the extension by releasing the quick-change latch and withdrawing the bit when the task is complete.

Usage recommendations

Use the extension with bits designed for the intended application and with tools rated for the required torque. Avoid excessive bending loads and side forces on the extension to prevent premature wear or bit slippage. For impact driving, confirm that both the tool and the bit are specified for impact use.
