It accepts drill bits and round-shank tooling ranging from 0.039 to 0.512 inches in capacity, covering the full range of common twist drill sizes for metal, wood, and plastic work. The chuck uses a ball bearing design and a steel body construction, providing consistent grip and durability under repeated use. It is installed by maintenance technicians, machinists, and tradespeople who require a reliable, hand-tightened chuck without a key. The closed length is 3.74 inches and the sleeve diameter is 1.73 inches.\u003c\/p\u003e\n\u003cp\u003eThe JACOBS 33364 is suited for benchtop drill presses, portable drilling equipment, and light-duty machine tool applications that accept a JT33 tapered arbor. Its keyless design allows for fast bit changes without a separate chuck key, making it practical in production and service environments where tooling changes are frequent. This chuck is a direct replacement option for worn or damaged keyless chucks on equipment originally fitted with JT33 tapered mounts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeyless tightening mechanism for fast, tool-free bit changes\u003c\/li\u003e\n  \u003cli\u003eJT33 tapered mount interfaces directly with compatible arbors\u003c\/li\u003e\n  \u003cli\u003eBall bearing design supports smooth rotation and consistent grip\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in industrial and trade use\u003c\/li\u003e\n  \u003cli\u003eWide capacity range of 0.039 to 0.512 inches accommodates common drill shank sizes\u003c\/li\u003e\n  \u003cli\u003eSleeve diameter of 1.73 inches fits standard chuck guard clearances on most drill press configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement keyless drill chuck for drilling equipment fitted with a JT33 tapered arbor mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this chuck onto a drill press or drilling machine should be performed with the machine fully powered down and locked out per OSHA lockout\/tagout procedures. The chuck seats onto the JT33 tapered arbor by firm hand pressure or a light mallet tap using a soft-faced hammer against the chuck body. To remove, use a chuck removal wedge or drift through the spindle slot  -  never strike the chuck body directly with a steel hammer. Verify the taper is clean and free of debris before seating the new chuck to ensure a secure fit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Chuck Capacity\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Chuck Capacity\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Size\u003c\/strong\u003e: JT33\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosed Length\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Length\u003c\/strong\u003e: 3.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Diameter\u003c\/strong\u003e: 1.73 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.375 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: 33364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67906428666162,"sku":"33364","price":252.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf99efade8f92052d58d04f1c21e3738.jpg?v=1791168080","url":"https:\/\/voomisupply.com\/products\/jacobs-33364-keyless-drill-chuck-jt33-tapered-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
