Designed for the KTFS series drill body system, this insert features a 13\/16 inch (0.8125 inch) cutting diameter and a PVD-applied AlTiN coating for heat and wear resistance at the cutting edge. The helical flute geometry uses a 2-flute, 2-margin configuration with a standard point type and regular spiral, suited for productive hole-making in steel and cast iron. Metalworking shops and machining operations running KTFS-series drill bodies use this replaceable tip to restore cutting performance without replacing the full drill body.\u003c\/p\u003e\u003cp\u003eThis insert is intended for production drilling applications in steel (ISO material group P) and cast iron (ISO material group K). Specific application categories supported include drilling on inclined exit surfaces and drilling through stacked plates, making it a practical option in structural fabrication, general machining, and die-mold environments. The insert does not include internal coolant-through capability. Functional length is 0.4063 inches and overall projection is 0.5799 inches, keeping the insert compact within the tool assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in fine grain KCP15A grade for edge stability in hard workpiece materials\u003c\/li\u003e\n\u003cli\u003ePVD AlTiN coating applied for thermal protection and extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry with 2-flute, 2-margin design for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eSupports inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003cli\u003eReplaceable tip format reduces tooling cost compared to full solid carbide drill replacement\u003c\/li\u003e\n\u003cli\u003eStandard point type with regular spiral for consistent entry and straightness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL KTFS series replaceable tip drill bodies accepting insert seat size Y and ISO style KTFSS.

The insert is held by a clamp mechanism within the drill body; follow the drill body manufacturer torque specifications for the clamping screw. Ensure the drill body and insert seating surfaces are clean and free of chips before seating the insert, as contamination at the interface can cause runout and premature insert failure. Do not exceed the recommended cutting parameters for the KCP15A grade on the selected workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP15A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS08125HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.4063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.5799 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.028 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6388663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743068455218,"sku":"6388663","price":246.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_dc2513a8-384e-483c-8a1b-bd1993866112.jpg?v=1788842196","url":"https:\/\/voomisupply.com\/products\/kennametal-6388663-carbide-replaceable-tip-drill-13-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
