The tip is manufactured from solid carbide fine-grain material with a PVD-applied TiAlN coating, delivering hardness and thermal resistance across demanding cutting conditions. The drill features a 40mm (1.5748 inch) cutting diameter, a 140-degree drill point angle, and an HPG insert geometry. Two helical flutes with through-coolant capability — including MQL (Minimum Quantity Lubricant) compatibility — support chip evacuation and tool life in production drilling environments. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for drilling operations in steel and cast iron workpieces, covering primary material grades P and K per ISO classification. The KSEM series design supports inclined exit drilling, stacked plate drilling, and standard through-hole applications. The clamp-style insert holding method secures the tip reliably during high-feed passes. A flute length of 20mm and overall projection of 0.7870 inches make this tool appropriate for moderate-depth hole applications in a machining center or CNC turning setup requiring consistent, repeatable bore quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain tip with PVD TiAlN coating for wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e40mm cutting diameter with 140-degree standard drill point angle\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry (ISO number KSEM4000HPGM) in KSEM series insert seat size 10\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design compatible with both flood coolant and MQL delivery systems\u003c\/li\u003e\n  \u003cli\u003eTwo helical flutes with 2-margin configuration for stable, accurate hole entry and exit\u003c\/li\u003e\n  \u003cli\u003eSupports inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement tip for KSEM series replaceable tip drill bodies accepting insert seat size 10.

Ensure the machine spindle is fully stopped and locked out before seating or removing the tip. Inspect the insert seat and clamping surfaces for chips or debris before securing the tip, as contamination can affect runout and tool life. Follow your facility's cutting fluid or MQL system setup guidelines to maintain proper coolant delivery through the tool body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 40mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7315\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM4000HPGM\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\u003eFlute Length\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.7870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron (ISO Grade P, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes (MQL Compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1896 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: 2449476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729022681394,"sku":"2449476","price":429.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_5ea71e0a-c5e2-4ef4-bb49-12746e213dac.jpg?v=1788698952","url":"https:\/\/voomisupply.com\/products\/kennametal-2449476-carbide-replaceable-tip-drill-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
