It accepts bit shanks from 1\/64 inch (0.0118 inch) up to 5\/32 inch (0.1563 inch), making it suited for small-diameter drilling work where precision and secure bit retention matter. The chuck uses a 5\/16-24 threaded mount and features a 22 mm sleeve diameter. Construction is steel with a plain bearing design. Licensed tradespeople and machinists working with bench drills, drill presses, and compatible rotary tools will find this chuck a reliable replacement or upgrade for light-duty precision drilling setups.\u003c\/p\u003e\n\u003cp\u003eThis chuck is appropriate for light industrial, maintenance, and trade shop environments where small-diameter bits are routinely used. It fits threaded spindles with a 5\/16-24 thread and is commonly installed on drill presses, hand drills, and rotary tools requiring a keyed chuck interface. The KO key type means a chuck key is required to tighten and release bits, providing positive grip during operation. It is a single-piece replacement unit packaged individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCapacity range from 1\/64 inch to 5\/32 inch for small-diameter bit applications\u003c\/li\u003e\n  \u003cli\u003eThreaded mount with 5\/16-24 thread size for secure spindle attachment\u003c\/li\u003e\n  \u003cli\u003eKeyed operation with KO key type for positive bit clamping\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003e22 mm sleeve diameter with plain bearing design\u003c\/li\u003e\n  \u003cli\u003eClosed length of approximately 1.73 inches and open length of approximately 1.50 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a threaded-mount replacement drill chuck for spindles with a 5\/16-24 thread.

Power down and disconnect the drill or drill press from its power source completely before removing or installing a chuck. Ensure the spindle threads are clean and undamaged before threading on the new chuck. Follow the tool manufacturer's guidelines for securing the chuck to the spindle to prevent loosening during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Capacity\u003c\/strong\u003e: 1\/64 inch (0.0118 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: 5\/16-24 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyed (KO Key)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 22 mm (approximately 0.87 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 44 mm (approximately 1.73 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 38 mm (approximately 1.50 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.76 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CY00417000MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744197771570,"sku":"CY00417000MSC","price":122.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ef6b84998c2f0b778f1e3a1a3703675.jpg?v=1788854926","url":"https:\/\/voomisupply.com\/products\/accupro-cy00417000msc-drill-chuck-threaded-5-16-24-keyed","provider":"Voomi Supply","version":"1.0","type":"link"}
