The insert carries Kennametal grade KC7315 with a PVD-applied TiAlN coating and an HPG geometry, delivering wear resistance and edge stability in demanding cutting conditions. It features a 140-degree drill point angle, two helical flutes with two margins, and through-coolant capability including MQL (Minimum Quantity Lubrication) compatibility. Cutting diameter is 15.48mm (39\/64 inch). This insert is specified and installed by machining professionals and toolroom technicians working with CNC drilling centers and machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 2499844 tip insert seats into KSEM-series replaceable-tip drill bodies using an A-series insert seat. Primary workpiece materials are steel (ISO material group P) and cast iron (ISO material group K). The HPG geometry and TiAlN finish make it well suited for through-hole and blind-hole drilling, inclined entry and exit surfaces, and stacked plate configurations where consistent hole quality is required across varying stack thicknesses. The helical regular-spiral flute form aids chip evacuation in these demanding setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain tip material with PVD TiAlN coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree standard drill point angle suited for steel and cast iron hole entry\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry optimized for stable, low-force cutting\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant channels support both flood coolant and MQL delivery\u003c\/li\u003e\n  \u003cli\u003e2-flute, 2-margin configuration for accurate hole geometry and controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eClamp-held insert seat (A-series) for repeatable indexing in KSEM-series drill bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM-series replaceable-tip drill bodies accepting an A-series insert seat.

Use the correct Kennametal clamping key or wrench specified for the KSEM body to seat the insert fully and evenly  -  do not overtighten by improvised means. Verify coolant port alignment before resuming cutting. Inspect the insert seat for chips or debris between each tip change to maintain runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 15.48mm (39\/64 inch \/ 0.6094 inch)\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3045 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 8.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes (flood and MQL compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: KSEM0609HPG\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\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: 0.0176 pounds\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: 2499844\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740480340274,"sku":"2499844","price":214.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_7069d93b-3afa-4572-b4b3-e0adaec4f31b.jpg?v=1788825292","url":"https:\/\/voomisupply.com\/products\/kennametal-2499844-carbide-replaceable-tip-drill-15-48mm","provider":"Voomi Supply","version":"1.0","type":"link"}
