The insert carries grade KCP15A, a fine-grain solid carbide formulation with an AlTiN coating applied via PVD process. The HPG insert geometry and helical flute design promote chip evacuation and cutting stability. This is a two-flute, two-margin insert with a standard point type and regular spiral, suited for demanding production drilling where tip replacement extends the usable life of the drill body without replacing the full assembly.\u003c\/p\u003e\u003cp\u003eThe 6388787 replaceable tip insert is intended for use in compatible KTFSS-series drill bodies in metalworking environments. Typical applications include through-hole and blind-hole drilling in steel and cast iron workpieces. The insert also supports inclined exit drilling and stacked-plate drilling operations, making it appropriate for aerospace, general machining, and fabrication shops where varied workpiece configurations are common. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KCP15A grade with fine-grain microstructure for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process improves heat resistance and tool life\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry engineered for stable cutting action and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eTwo-flute, two-margin design supports tight hole tolerances\u003c\/li\u003e\n\u003cli\u003eRated for inclined exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure, repeatable seating in KTFSS-series bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KTFSS-series replaceable tip drill bodies accepting an R-seat insert size with a 9\/16 inch cutting diameter.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before seating or removing the replaceable tip. Clean the insert pocket and seating surfaces before installation to ensure accurate tip runout. Do not exceed the drill body manufacturer's recommended feed and speed parameters for the KCP15A grade.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: R\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: KTFSS05625HPG\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4033 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.00 mm\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\u003eApplications\u003c\/strong\u003e: Drilling, Inclined Exit Drilling, Stacked Plate Drilling\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: 0.1239 pounds\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: 6388787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740499476786,"sku":"6388787","price":161.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_aa0f554b-53cd-48b6-9e5c-4e705b9333d7.jpg?v=1788825433","url":"https:\/\/voomisupply.com\/products\/kennametal-6388787-carbide-replaceable-tip-drill-9-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
