The tip features a solid carbide construction with a KC7315 fine-grain substrate and a PVD-applied TiAlN coating that resists heat and wear in demanding cutting conditions. The 140-degree drill point angle and HPG insert geometry promote self-centering and chip control. With a cutting diameter of 18mm (0.7087 inches) and through-coolant capability including MQL support, this insert is built for machine shop and production environments where consistency and tool life matter. Licensed machinists and CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill insert is suited for drilling operations in ferrous materials, specifically steel (ISO material code P) and cast iron (ISO material code K). It fits applications involving standard through-hole drilling, inclined exit drilling, and stacked plate drilling. The 2-flute, 2-margin helical flute design and clamp-style insert holding method make it appropriate for CNC machining centers running high-volume production cycles. The through-coolant channels support both flood coolant and minimum quantity lubrication delivery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KC7315 fine-grain substrate for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating reduces thermal load and extends tool life\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for accurate self-centering entry\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry with 2-flute, 2-margin helical configuration for chip evacuation\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design compatible with flood coolant and MQL systems\u003c\/li\u003e\n\u003cli\u003eSupports inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM series replaceable tip drill bodies accepting insert seat size 1.

Follow the tool body manufacturer torque guidelines for the clamp holding method when seating the replaceable tip. Verify coolant port alignment before running to ensure proper through-coolant flow. Confirm insert seat cleanliness and freedom from chips or debris before clamping to maintain runout accuracy.\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3544 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 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\u003c\/strong\u003e: TiAlN\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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003eCoolant Through\u003c\/strong\u003e: Yes (flood and MQL compatible)\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\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM1800HPGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0077 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: 2499763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750173311282,"sku":"2499763","price":240.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_16975860-5fa8-4e01-b839-54342f9115c5.jpg?v=1788914054","url":"https:\/\/voomisupply.com\/products\/kennametal-2499763-carbide-replaceable-tip-drill-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
