Irwin 1869516 Impact Performance Series Quick-Change Bit Extension, 1/4-Inch Shank, 6-Inch

Irwin 1869516 Impact Performance Series Quick-Change Bit Extension, 1/4-Inch Shank, 6-Inch

The Irwin 1869516 Impact Performance Series Quick-Change Bit Extension is purpose-built for professionals and serious DIYers who rely on impact drivers to get fasteners driven quickly and securely. Engineered for maximum durability and long life, this 6-Inch extension accepts standard 1/4-Inch hex shank accessories, including insert bits, and is designed to hold up to the repeated high-torque impacts that can quickly wear out lesser-quality bit holders. The 1/4-Inch quick-change shank is sized to work directly with impact drivers while also reducing slipping when chucked into a standard drill, giving you one accessory that performs reliably across multiple tools. A black oxide finish helps the extension resist corrosion from moisture, sweat, and jobsite conditions, extending its usable life well beyond uncoated alternatives.

Key Features

• Trade Size: 1/4-Inch quick-change hex shank is sized to work with impact drivers and also reduces slipping when used in standard drill chucks, so the same extension moves easily between tools.
• Patented Jaw Design: The quick-change jaw is compatible with all 1/4-Inch hex shank accessories, including insert bits, allowing fast, tool-free bit swaps on the jobsite.
• Large Chuck for High Torque: A large chuck is built to withstand the higher torque demands generated by impact drivers, helping prevent bit slippage and premature wear during heavy-duty fastening.
• Corrosion-Resistant Finish: A black oxide finish resists corrosion and increases the overall service life of the extension in demanding work environments.
• 6-Inch Length: The 6-Inch overall length extends reach into recessed, deep, or hard-to-access fastener locations where a standard bit alone can't reach.
