This drill features a solid carbide tip in grade KCP15A with an AlTiN (aluminum titanium nitride) coating applied via PVD process, delivering strong wear resistance and heat tolerance at elevated cutting speeds. The 143-degree included angle and HPG insert geometry are optimized for aggressive chip formation and stable entry in a wide range of workpiece materials. Machinists and toolroom professionals working on CNC machining centers will find this drill well suited to high-throughput production environments where tip replaceability reduces tooling downtime.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is used in metal-cutting operations on CNC machining centers and drill presses in both job shop and production floor settings. The 18mm cutting diameter (0.7087 inches) places it in a common range for structural, mechanical, and die-mold drilling applications. The KTFS series platform accepts W-seat insert sizing, and the HPG geometry is matched to the KCP15A grade for optimized performance in steel and cast materials. No through-coolant is provided on this configuration, making it appropriate for setups where external coolant delivery is standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KCP15A grade tip for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process for thermal resistance and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003e143-degree included angle for stable drill entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry promotes efficient chip evacuation and controlled cutting action\u003c\/li\u003e\n\u003cli\u003eW-seat insert sizing within the KTFS series platform for repeatable tip indexing\u003c\/li\u003e\n\u003cli\u003eReplaceable tip design reduces cost per hole compared to solid shank alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use within the KENNAMETAL KTFS series replaceable tip drill platform using W insert seat sizing.

Use the manufacturer-recommended torque wrench and seating tool to secure the carbide tip to the drill body  -  never use impact tools or improvised wrenches on carbide inserts. Inspect the insert seat for chips or debris before seating a new tip, as contamination can cause premature tip failure or runout. Follow applicable shop safety protocols and machine guarding requirements during tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 18mm (0.7087 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: W\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\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: 6388579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740811559218,"sku":"6388579","price":222.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_813a0f5f-d784-4d97-bac1-5b64566eceba.jpg?v=1788827548","url":"https:\/\/voomisupply.com\/products\/kennametal-6388579-carbide-replaceable-tip-drill-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
