It measures 10 inches in diameter and mounts via a D1-8 direct camlock spindle connection. The chuck body is cast iron, providing rigidity and vibration damping during turning operations. Jaws are two-piece and reversible, allowing the chuck to grip both outside and inside diameters without a jaw swap. The through-hole diameter is 2.7559 inches (70 mm), accommodating bar stock fed through the spindle. This chuck is installed by machinists and toolroom technicians in job shop and production turning environments.\u003c\/p\u003e\n\u003cp\u003eThe 429-3108 is suited for manual lathes with a D1-8 camlock spindle nose in both job shop and light production settings. The self-centering scroll mechanism allows fast, repeatable workpiece setup for round and hex stock. The reversible two-piece jaw set extends the range of workpiece diameters the chuck can hold without requiring additional jaw sets. Typical applications include turning, facing, and boring operations on ferrous and non-ferrous materials in a machine shop environment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-inch chuck diameter for medium to large lathe work\u003c\/li\u003e\n  \u003cli\u003eSelf-centering 3-jaw scroll design for fast, repeatable workpiece location\u003c\/li\u003e\n  \u003cli\u003eD1-8 direct camlock mount for secure, tool-free spindle attachment\u003c\/li\u003e\n  \u003cli\u003eReversible two-piece jaws extend gripping range for both small and large diameters\u003c\/li\u003e\n  \u003cli\u003e2.7559-inch (70 mm) through-hole diameter accommodates bar stock fed through the spindle\u003c\/li\u003e\n  \u003cli\u003eCast iron body provides rigidity and damping during cutting operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for manual engine lathes and turning centers equipped with a D1-8 camlock spindle nose.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the lathe powered off, spindle locked, and the machine isolated from its power source. The D1-8 camlock studs should be inspected and cleaned before mounting; engage all camlock pins evenly and verify secure seating before operation. Always confirm runout with a dial indicator after mounting before taking the first cut. Jaw removal and reversal should be performed with the chuck off the spindle on a clean, stable work surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Jaws\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Type\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Direct Camlock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Mounting Size\u003c\/strong\u003e: D1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough-Hole Diameter\u003c\/strong\u003e: 2.7559 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Configuration\u003c\/strong\u003e: Two-Piece, Reversible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 82 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112807\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 429-3108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691388633394,"sku":"429-3108","price":783.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64cbe4ed579c5a7391411980421a26f3.jpg?v=1788284354","url":"https:\/\/voomisupply.com\/products\/value-collection-429-3108-10-in-3-jaw-lathe-chuck-d1-8","provider":"Voomi Supply","version":"1.0","type":"link"}
