It carries the KTFSS06719HPG ISO designation and is manufactured to the KCP15A grade using a fine-grain carbide substrate with a PVD-applied AlTiN coating. The insert seats into KTFS-series drill bodies using a clamp-style holding method and delivers a 180-degree drill point angle with an HPG insert geometry. Cutting diameter is 0.5000 inches (43\/64 inch), with a functional length of 0.3360 inches and an overall projection of 0.4805 inches. This insert is specified and installed by machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip is intended for drilling into steel and cast iron workpieces, covering ISO material codes P and K. The HPG geometry supports demanding drilling scenarios including inclined entry and exit surfaces, stacked plate configurations, and standard through-hole and blind-hole drilling. The 2-flute, 2-margin, helical flute design with regular spiral promotes chip evacuation in these challenging setups. Coolant-through capability is not incorporated in this insert. The insert is sold individually and is compatible with KTFS-series replaceable tip drill bodies sized for the V insert seat.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide KCP15A fine-grain substrate for wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePVD AlTiN coating extends tool life in dry and semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry supports inclined-exit, stacked-plate, and standard drilling applications\u003c\/li\u003e\n  \u003cli\u003e2-flute, 2-margin helical flute design promotes chip control and hole quality\u003c\/li\u003e\n  \u003cli\u003e180-degree drill point angle for consistent entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eClamp-style retention in V-seat KTFS-series drill bodies for repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KTFS-series replaceable tip drill bodies configured for a V insert seat.

The drill body must be fully de-energized and the spindle locked before removing or seating the insert. Use the appropriate clamp key or torx driver specified by the drill body manufacturer to seat the insert  -  do not overtighten or substitute fasteners. Inspect the insert seat and clamping surfaces for chips or contamination before each insertion to ensure accurate seating and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 43\/64 inch (0.5000 inches \/ 12.70 mm)\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 Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS06719HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\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, Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4805 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12.00 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 (ISO P, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6388554\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741804101938,"sku":"6388554","price":200.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_bdb4013c-447f-4b88-9ac1-57b4c72349c6.jpg?v=1788833563","url":"https:\/\/voomisupply.com\/products\/kennametal-6388554-carbide-replaceable-tip-drill-43-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
