Manufactured in the TDHB insert style with a triangular 60-degree included angle, this insert carries a TiN (titanium nitride) PVD coating and the KC730 manufacturer grade. It features a 0.1600-inch inscribed circle, a 0.0079-inch corner radius, a 15-degree relief angle, and a positive rake geometry with a flat-top chipbreaker. The screw-on holding method provides secure seating under interrupted and continuous cuts. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel, stainless steel, superalloys, and titanium — corresponding to ISO material codes P, M, and S. It is well matched to light-to-moderate roughing and finishing passes, with a maximum depth of cut of 1.25 mm (0.0492 inches). The flat-top chipbreaker geometry promotes chip control during high-feed operations on difficult-to-machine alloys. The three available cutting edges extend tool life and reduce per-edge cost in high-volume turning applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape with three usable cutting edges\u003c\/li\u003e\n\u003cli\u003ePositive rake, flat-top chipbreaker geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces flank wear on difficult materials\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for repeatable, rigid insert positioning\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw-on turning insert conforming to ANSI and ISO standards for TDHB-style insert seats in compatible turning toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before changing inserts. Use the appropriate Torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as carbide inserts are brittle and can fracture under excessive clamping force. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDHB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 12807505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.1600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.2772 inches (7.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0950 inches (2.39 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Screw-On\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: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1175040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727516074290,"sku":"1175040","price":171.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1046c3a8cb630cc2fd1ea59297a59c7b.jpg?v=1788678789","url":"https:\/\/voomisupply.com\/products\/kennametal-1175040-turning-insert-kc730-carbide-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
