With a 6-19\/64 inch (159.94 mm) chuck diameter and a plain back mount, this chuck provides reliable workpiece clamping across a range of cylindrical and irregular stock. The two-piece reversible jaws allow the chuck to grip both small-diameter and larger-diameter workpieces without swapping jaw sets. Cast iron body construction provides rigidity and dampens vibration during cuts. Machinists and tool room operators working with manual lathes in job shops, maintenance facilities, and production environments will find this chuck straightforward to set up and use.\u003c\/p\u003e\n\u003cp\u003eThis chuck is suited for manual lathe applications in both light production and general-purpose machining environments. The self-centering scroll mechanism allows all three jaws to move simultaneously, reducing setup time when chucking round or hex stock. The reversible two-piece jaws extend the gripping range without requiring separate jaw sets. A through-hole diameter of 1.535 inches accommodates bar stock fed through the spindle. The plain back mount requires a backing plate matched to the lathe spindle nose — verify spindle nose type and thread before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-19\/64 inch (159.94 mm) chuck diameter for mid-size lathe applications\u003c\/li\u003e\n  \u003cli\u003eSelf-centering 3-jaw scroll design — all jaws move simultaneously for fast workpiece setup\u003c\/li\u003e\n  \u003cli\u003eReversible two-piece jaws expand gripping range for both small and large-diameter stock\u003c\/li\u003e\n  \u003cli\u003e1.535 inch through-hole diameter supports bar stock fed through the spindle\u003c\/li\u003e\n  \u003cli\u003eCast iron body for rigidity and vibration damping during turning operations\u003c\/li\u003e\n  \u003cli\u003eTIR repeatability of 0.013 mm for consistent runout performance across setups\u003c\/li\u003e\n  \u003cli\u003ePlain back mount for compatibility with a wide range of backing plate configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style manual lathe chuck with a plain back mount.

Power down and lock out the lathe before mounting or removing the chuck. The plain back design requires a precision-fit backing plate — do not mount the chuck directly to the spindle without a properly bored and faced adapter plate. After installation, verify runout with a dial indicator before resuming machining operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Diameter\u003c\/strong\u003e: 6-19\/64 inches (159.94 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\u003eJaw Style\u003c\/strong\u003e: Two-Piece, Reversible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Plain Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough-Hole Diameter\u003c\/strong\u003e: 1.535 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Repeatability\u003c\/strong\u003e: 0.013 mm\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: 20 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: 429-36001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701151531314,"sku":"429-36001","price":482.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf771fe0254872c9d7dde4e19a9af78c_20b9b3e5-1703-461d-b607-54cb76316783.jpg?v=1788398891","url":"https:\/\/voomisupply.com\/products\/value-collection-429-36001-manual-lathe-chuck-3-jaw","provider":"Voomi Supply","version":"1.0","type":"link"}
