This solid carbide insert features a 0.3906 inch cutting diameter, a 180-degree point angle, and an AlTiN coating applied via PVD process. The KCP15A grade uses fine-grain carbide for wear resistance in demanding drilling applications. Seat size I and the HPG insert geometry provide secure clamping and consistent chip evacuation. Machinists and tooling technicians install this tip as a replaceable cutting element, extending tool body life while maintaining hole accuracy.\u003c\/p\u003e\n\u003cp\u003eThis drill tip is suited for drilling steel and cast iron in both production and job-shop environments. It handles demanding setups including inclined exit surfaces and stacked plate configurations. The 2-flute, 2-margin helical flute design with regular spiral supports stable cutting action in P and K workpiece material groups. The clamp-held insert method allows fast tip changes at the machine without removing the drill body from the spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in fine-grain KCP15A grade for durability in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating via PVD process for thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e180-degree point angle with HPG insert geometry for stable entry and exit\u003c\/li\u003e\n  \u003cli\u003e2-flute, 2-margin helical configuration supports chip control without through-coolant\u003c\/li\u003e\n  \u003cli\u003eRated for inclined exit and stacked plate drilling applications\u003c\/li\u003e\n  \u003cli\u003eClamp-held seat size I for repeatable indexing and secure retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KTFSS series modular drill bodies accepting a seat size I replaceable tip.

Ensure the spindle is stopped and the machine is in a safe, locked-out state before indexing or replacing the tip. Use the recommended torque driver or clamp key specified for the KTFSS body to seat the insert properly. Do not exceed the cutting parameters published in the KENNAMETAL application guide for the workpiece material and drill body diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3906 inches (25\/64 inches)\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: 0.1953 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.2807 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP15A\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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\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\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\u003eISO Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Drilling, Inclined Exit Drilling, Stacked Plates Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS03906HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6388668\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740057567538,"sku":"6388668","price":156.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5227a20684416e21ce26d42b5e4f4173_03570c42-143b-4167-860e-f540e3fbd892.jpg?v=1788821925","url":"https:\/\/voomisupply.com\/products\/kennametal-6388668-replaceable-drill-tip-0-3906-in-kcp15a","provider":"Voomi Supply","version":"1.0","type":"link"}
