The tip carries a KCP15A grade solid carbide insert with an AlTiN coating applied via PVD process, providing thermal resistance and wear protection in demanding cutting conditions. The drill point geometry uses an HPG insert profile at a 143-degree included angle, producing self-centering entry and reduced thrust. This style of replaceable tip drill is installed and serviced by machinists and toolroom technicians on CNC machining centers and drill presses.\u003c\/p\u003e\u003cp\u003eThis drill is suited for production environments requiring consistent hole quality in ferrous and non-ferrous materials. The 14mm cutting diameter (0.5512 inches) targets general-purpose drilling operations in manufacturing and job shop settings. The replaceable tip design reduces per-hole tooling cost compared to solid integral drills by allowing tip exchange without discarding the drill body. Insert seat size is R, which determines tip-to-body fitment within the KTFS platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14mm (0.5512 inch) cutting diameter in the KTFS replaceable tip series\u003c\/li\u003e\n\u003cli\u003eKCP15A grade solid carbide tip for high-performance metal cutting\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e143-degree drill point angle with HPG insert geometry for reduced thrust and accurate entry\u003c\/li\u003e\n\u003cli\u003eInsert seat size R for direct replacement within the KTFS body platform\u003c\/li\u003e\n\u003cli\u003eNo through-coolant design  -  suitable for external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip insert for KTFS series drill bodies accepting an R seat size.

Ensure the machine spindle is fully stopped and the tool is secured in a vise or tool holder before tip removal or installation. Follow the drill body manufacturer torque guidance for the clamping screw using a calibrated torque wrench. Inspect the insert seat for chips or debris before seating the new tip to maintain runout and hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 14mm (0.5512 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\u003eSeries\u003c\/strong\u003e: KTFS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 143 degrees\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\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: 6388781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743675056434,"sku":"6388781","price":161.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_29e517a3-4668-436a-9e26-6aa51fb8f44e.jpg?v=1788849206","url":"https:\/\/voomisupply.com\/products\/kennametal-6388781-carbide-replaceable-tip-drill-14mm-ktfs","provider":"Voomi Supply","version":"1.0","type":"link"}
