Manufactured from fine grain solid carbide with a KCP15A grade and PVD-applied AlTiN coating, this tip delivers wear resistance and thermal stability during demanding drilling operations. It features a 180-degree point angle with an HPG insert geometry and a helical, regular-spiral flute design with two flutes and two margins. The insert seat size is T, and the tip is held in place by a clamp mechanism. Machining professionals and toolroom technicians working with steel and cast iron will find this tip suited for precision modular drilling setups.\u003c\/p\u003e\u003cp\u003eThis replaceable tip is intended for use in applications involving standard drilling, inclined-exit drilling, and stacked-plate drilling. The two-flute, two-margin, no-coolant-through configuration makes it appropriate for setups where internal coolant delivery is not required. Primary workpiece materials are steel and cast iron, corresponding to ISO material groups P and K. It is packaged individually and sold in single-unit quantities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFine grain solid carbide construction in KCP15A grade for strength and wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD-applied AlTiN coating for thermal stability and extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e180-degree point angle with HPG insert geometry for accurate entry and exit\u003c\/li\u003e\n\u003cli\u003eTwo-flute, two-margin, regular helical spiral design without coolant-through\u003c\/li\u003e\n\u003cli\u003eClamp-held insert seat size T for secure, repeatable positioning in KTFSS-series holders\u003c\/li\u003e\n\u003cli\u003eRated for inclined-exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KTFSS-series modular drill bodies that accept insert seat size T replaceable tips.

Power down and lock out the machine spindle before removing or installing any replaceable tip. Use the appropriate torque wrench and clamping hardware specified by the holder manufacturer  -  do not overtighten or substitute fasteners. Inspect the seat and clamping surfaces for debris or wear before seating the new tip to ensure proper contact and runout accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.4219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 10.72 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\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: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\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\u003eFunctional Length\u003c\/strong\u003e: 0.3047 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4362 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 11.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003ePackage Weight\u003c\/strong\u003e: 0.03 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: 6388828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743947587890,"sku":"6388828","price":161.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5227a20684416e21ce26d42b5e4f4173_994584c8-ff70-4bfe-a0c3-2b892bb3655f.jpg?v=1788851745","url":"https:\/\/voomisupply.com\/products\/kennametal-6388828-replaceable-drill-tip-0-4219in-kcp15a","provider":"Voomi Supply","version":"1.0","type":"link"}
