Manufactured from case hardened steel, this jaw delivers the surface durability required for high-cycle turning and machining operations. The serrated jaw interface provides positive, repeatable seating against the chuck body, maintaining consistent grip force during cuts. Sold as a set of three jaws, the 159100 is a direct replacement component for worn or damaged master jaws on compatible lathe chuck assemblies. Machinists and tool room technicians who perform in-house chuck maintenance will find this a straightforward, spec-matched replacement.\u003c\/p\u003e\n\u003cp\u003eThis master jaw is suited for manual and CNC lathe applications in job shops, production turning cells, and maintenance departments. It is intended for installation into chuck bodies with a 20 mm slot width and a serrated interface. The jaw interfaces directly with the chuck body master groove, serving as the foundation for top jaws or soft jaws that are machined to workpiece geometry. No step profile is present on this jaw, consistent with a clean master-jaw configuration intended to accept field-machined top jaws.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCase hardened steel construction resists wear under repeated clamping cycles\u003c\/li\u003e\n  \u003cli\u003eSerrated jaw interface type ensures positive, repeatable chuck body engagement\u003c\/li\u003e\n  \u003cli\u003eCompatible with lathe chucks up to 200 mm in diameter\u003c\/li\u003e\n  \u003cli\u003e20 mm slot width matches standard chuck body groove dimensions\u003c\/li\u003e\n  \u003cli\u003eSet of 3 jaws provides a complete master jaw replacement in one order\u003c\/li\u003e\n  \u003cli\u003eZero-step master jaw profile accepts field-machined top jaws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement master jaw for serrated-interface lathe chucks with a maximum chuck diameter of 200 mm and a 20 mm slot width.

Power down the lathe and engage the spindle lock before removing or installing chuck jaws. Verify that the serrated interface and slot width of the chuck body match the jaw specifications prior to assembly. Follow the chuck manufacturer torque and seating procedures to ensure proper jaw retention and safe workholding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Type\u003c\/strong\u003e: Master\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Interface Type\u003c\/strong\u003e: Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Case Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Compatible Chuck Diameter\u003c\/strong\u003e: 200 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Jaws\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 29.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 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: SCHUNK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 159100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHUNK","offers":[{"title":"Default Title","offer_id":67912345059634,"sku":"159100","price":479.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1c8bbd8c544ad34d9eacc088dcc1d2c_0f7442cb-1def-4ab2-a32f-5a6c652f4bd8.jpg?v=1791233618","url":"https:\/\/voomisupply.com\/products\/schunk-159100-hard-lathe-chuck-jaw-master-serrated","provider":"Voomi Supply","version":"1.0","type":"link"}
