Designed for high-performance drilling operations, this tool accepts a solid carbide tip with HPG insert geometry and a standard point type. The cutting diameter measures 14.30 mm (0.563 inches), with a flute length of 7.00 mm and an overall projection of 0.4035 inches. Two helical flutes with a regular spiral provide chip evacuation during drilling. The insert is secured via clamp-style holding in an R-seat size. This replaceable tip design reduces tooling cost by allowing tip exchange without replacing the full shank body.\u003c\/p\u003e\u003cp\u003eThis drill is intended for use on steel and cast iron workpieces, corresponding to ISO material codes P and K. It is suited for standard drilling as well as inclined exit drilling and stacked plate drilling applications. The HPG geometry and AlTiN finish support demanding production environments where tool life and surface finish consistency are priorities. It is typically used in CNC machining centers and production turning operations. Installation and tip replacement are performed by machining technicians or toolroom personnel following the manufacturer seating and torque procedures for the clamp-style insert holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KTFSS replaceable tip with KCP15A fine grain grade\u003c\/li\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry optimized for steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with regular spiral for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding in R-seat size for secure tip retention\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 as an OEM-style replaceable tip for KTFSS-series drill bodies accepting an R insert seat size.

Ensure the insert seat is clean and free of chips or debris before seating the carbide tip. Follow the manufacturer clamp torque sequence for the KTFSS seat style. Do not exceed the recommended cutting parameters for the KCP15A grade when programming feeds and speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 14.30 mm (0.563 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\u003eSeries\u003c\/strong\u003e: KTFSS\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\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\u003eFlute Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2815 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.4035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.00 mm (0.59 inches)\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\u003eApplications\u003c\/strong\u003e: Drilling, Inclined Exit Drilling, Stacked Plates 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: 0.028 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: 6388789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742998855986,"sku":"6388789","price":161.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_51a7d545-db71-4319-b6da-8b627c748e2c.jpg?v=1788841401","url":"https:\/\/voomisupply.com\/products\/kennametal-6388789-carbide-replaceable-tip-drill-14-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
