Built with a carbon steel sleeve and body, this extension delivers durable performance in demanding trade and jobsite environments. The patented jaw design grips bits securely on 6 flats as well as ball detent bits, while the Lock-N-Load system allows for one-handed quick release without fumbling. It accepts standard 1\/4-inch insert bits and is engineered to work across a wide range of accessories including spade bits, fastener drives, step bits, hole saw arbors, and countersinks. Electricians, plumbers, HVAC technicians, and general contractors working in confined spaces will benefit from this compact extension.\u003c\/p\u003e\u003cp\u003eThis extension is suited for residential and light commercial construction and service work where extended reach and fast bit changes are essential. It is commonly used in framing, electrical rough-in, plumbing, and HVAC install scenarios where drilling clearance is limited. The 2-inch length adds reach without significantly altering chuck-to-work distance, making it practical for tight cabinet or wall cavity work. It ships in a package quantity of 6, making it a practical stocking item for supply rooms or field kits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePatented jaw design grips bits on 6 flats and ball detent styles for a secure hold\u003c\/li\u003e\n\u003cli\u003eLock-N-Load system enables one-handed quick release for fast bit swaps\u003c\/li\u003e\n\u003cli\u003eCarbon steel sleeve and body construction for long service life\u003c\/li\u003e\n\u003cli\u003eAccepts 1\/4-inch insert bits and works with multiple accessory types\u003c\/li\u003e\n\u003cli\u003eCompatible with Irwin Speedbor Blue Groove and Speedbor Max spade bits in sizes 7\/16 inch to 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003eWorks with Unibit sizes 1, 2, 10, and 12, hole saw arbors from 9\/16 inch to 1-3\/16 inches, and countersinks sizes 4 through 12\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Irwin Speedbor Blue Groove bits, Speedbor Max bits in sizes 7\/16 inch to 1-1\/4 inches, all fastener drives, Unibit sizes 1, 2, 10, and 12, 1\/4-inch hole saw arbor sizes 9\/16 inch to 1-3\/16 inches, and countersinks sizes 4 through 12.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this extension by hand — no tools are required to seat or release bits using the Lock-N-Load mechanism. Ensure the drill or driver is powered off and the trigger is locked before changing bits or attaching the extension. Inspect the jaw and detent mechanism periodically for wear or debris that could reduce holding force. This accessory is intended for use with rotary drills and drivers; do not use with hammer-drill mode engaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch quick-change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtension Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Carbon steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN INDUSTRIAL TOOL CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4935703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51559017447730,"sku":"4935703","price":79.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da4c70d5066771e540b914c24e56c56c.jpg?v=1786425851","url":"https:\/\/voomisupply.com\/products\/irwin-industrial-tool-co-4935703-quick-chuck-extension","provider":"Voomi Supply","version":"1.0","type":"link"}
