It accepts bit shanks from 0.012 to 0.291 inches, covering a wide range of twist drills, step bits, and driver accessories. The chuck uses a 3\/8-24 threaded mount for secure spindle attachment and incorporates a ball bearing design for smooth, consistent tightening without a key. The stainless steel chuck body resists corrosion in shop environments. Sleeve diameter measures 30 millimeters. Closed length is approximately 2.47 inches and open length is approximately 2.20 inches. This unit weighs 0.63 pounds and ships as a single piece.\u003c\/p\u003e\u003cp\u003eThis keyless chuck is suited for residential and light commercial trade work, including use by electricians, plumbers, and HVAC technicians who operate cordless or corded drills with a 3\/8-24 spindle thread. It fits standard drill press spindles and handheld drill motors that use this threaded interface. The keyless collar allows single-hand bit changes in the field, which reduces downtime during repetitive drilling tasks such as wire fishing, pipe penetrations, and bracket mounting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKeyless design allows bit changes without a chuck key\u003c\/li\u003e\n\u003cli\u003eCapacity range of 0.012 to 0.291 inches accommodates twist drills through large-diameter bits\u003c\/li\u003e\n\u003cli\u003eBall bearing construction provides smooth collar operation and consistent grip force\u003c\/li\u003e\n\u003cli\u003eStainless steel chuck body for corrosion resistance in demanding work environments\u003c\/li\u003e\n\u003cli\u003e3\/8-24 threaded mount for direct spindle attachment\u003c\/li\u003e\n\u003cli\u003e30 millimeter sleeve diameter with compact overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drill motors and drill press spindles equipped with a 3\/8-24 threaded mount interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified technician familiar with rotating tool hardware. Power off and unplug the drill or drill press before removing the existing chuck or installing this unit. Thread the chuck onto the spindle by hand first, then tighten firmly in the direction of normal drill rotation to prevent self-loosening during use. Inspect the spindle threads for damage or debris before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 0.012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 0.291 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChuck Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 30 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 2.47 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 2.20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PNI0709100MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730310463794,"sku":"PNI0709100MSC","price":671.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ad059f2437dc8c144f8b880b1f765e6.jpg?v=1788715118","url":"https:\/\/voomisupply.com\/products\/accupro-pni0709100msc-keyless-drill-chuck-3-8-24-threaded-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
