Built from steel, it accepts round-shank drill bits and other rotary tooling across its full capacity range. The sleeve diameter measures 1.43 inches, and the closed length is 2.5 inches, making it a compact, direct-mount chuck suited for benchtop drill presses, handheld drills, and light machine tool spindles. Tightening is performed with the included K30 key for positive grip and repeatable runout control. Machinists, maintenance technicians, and tool-room professionals install this chuck as a replacement or upgrade on threaded-spindle equipment.\u003c\/p\u003e\n\u003cp\u003eThis chuck is designed for use on drilling equipment with a 3\/8-24 threaded spindle nose. Typical applications include light-duty drill presses, portable electric drills, and similar rotary tools found in production, maintenance, and fabrication environments. The plain bearing design keeps the profile simple and the unit easy to service. It handles both small-diameter bits near 0.039 inches and full 3\/8 inch tooling without adapter changes, covering the range most commonly encountered in general mechanical and light manufacturing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch maximum capacity accepts a wide range of standard drill bits and rotary tooling\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 threaded mount for direct installation on compatible spindle noses\u003c\/li\u003e\n  \u003cli\u003eKeyed design with K30 key provides secure, positive clamping force\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in production and maintenance use\u003c\/li\u003e\n  \u003cli\u003e1.43 inch sleeve diameter and 2.5 inch closed length for compact fitment\u003c\/li\u003e\n  \u003cli\u003ePlain bearing construction simplifies maintenance and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-replacement keyed drill chuck for threaded-spindle drilling equipment with a 3\/8-24 spindle nose thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or maintenance technician. Before mounting or removing the chuck, disconnect power to the drill or press and allow all rotating components to come to a complete stop. Thread the chuck clockwise onto the 3\/8-24 spindle nose and secure it according to the equipment manufacturer's procedure. Use the K30 key to tighten the chuck jaws onto tooling before each use, and never operate the chuck with the key inserted in the socket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Chuck Capacity\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Chuck Capacity\u003c\/strong\u003e: 0.0394 inches\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: 3\/8-24 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: K30\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\u003eClosed Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 1.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: JACOBS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JCM32282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67911997456690,"sku":"JCM32282","price":96.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d62d992d14e8c3ea03dd592a028540df.jpg?v=1791224495","url":"https:\/\/voomisupply.com\/products\/jacobs-jcm32282-drill-chuck-3-8-in-keyed-threaded-3-8-24","provider":"Voomi Supply","version":"1.0","type":"link"}
