This hardware component threads into the insert pocket and clamps the cutting insert firmly in place during machining operations, maintaining precise positioning under cutting loads. It carries a 1\/4-18 thread specification and is built for use in indexable drilling applications where reliable insert retention is critical. Installation is performed by tooling technicians or machinists during insert changeover on CNC or manual drilling setups.\u003c\/p\u003e\n\u003cp\u003eThis central lock screw is used in indexable drilling toolholders that accept compatible insert-locking hardware. It is a direct-replacement maintenance consumable, typically stocked alongside indexable inserts and replaced as part of routine toolholder servicing when screw threads show wear or damage. Suitable for production machining environments in metal removal applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-18 thread size for precise insert clamping in indexable drilling holders\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically as a central lock screw for indexable insert retention\u003c\/li\u003e\n  \u003cli\u003eCompatible with drilling-type indexable toolholders\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at approximately 0.05 pounds per unit\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with indexable drilling toolholders requiring a 1\/4-18 central lock screw for insert retention.

Always ensure the spindle or machine is fully powered down and locked out before servicing the toolholder. Use the appropriate Torx or hex key driver specified by the toolholder manufacturer when seating the lock screw. Do not overtighten, as this can damage the screw threads or the insert pocket seating surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Central Lock Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1130295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749554684210,"sku":"1130295","price":245.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2966fd396598e1c3cea511854850e13.jpg?v=1788907552","url":"https:\/\/voomisupply.com\/products\/kennametal-1130295-central-lock-screw-1-4-18-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
