The tip is manufactured from solid carbide with a fine grain substrate and carries a PVD-applied TiAlN coating for heat and wear resistance. The HPG insert geometry and 140-degree drill point angle promote controlled chip formation and accurate entry. With a cutting diameter of 20.24mm (0.7968 inches) and two helical flutes, this insert seats into size-3 KSEM tool bodies and is secured by a clamp-style holding method. It weighs approximately 0.033 pounds and is sold individually.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill insert is suited for production drilling in ferrous materials, including steel (ISO material code P) and cast iron (ISO material code K). The through-coolant design supports both flood coolant and MQL (minimum quantity lubricant) delivery, making it appropriate for high-throughput machining operations. Typical applications include straight drilling, inclined exit drilling, and stacked plate drilling. The clamp-held carbide tip allows fast tip changes without removing the tool body from the spindle, reducing downtime in CNC machining center environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide tip with fine grain substrate for edge stability in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating provides thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle suits standard drilling in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable  -  supports flood coolant and MQL delivery\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry with 2-flute, 2-margin configuration for accurate hole geometry\u003c\/li\u003e\n  \u003cli\u003eClamp-held insert seat (size 3) enables rapid tip replacement without tool body removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM series tool bodies accepting a size-3 insert seat.

Power down and lock out the machine spindle before seating or removing the carbide tip. Use the manufacturer-specified torque wrench and clamp screw to secure the insert  -  do not use impact tools on the clamp screw. Verify coolant port alignment and confirm the insert is fully seated before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 20.24mm (0.7968 inches)\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: KSEM0797HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7315\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\u003eCoating\/Finish\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\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\u003eSpiral Type\u003c\/strong\u003e: 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3985 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.5395 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 14.00mm\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\u003eISO Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 2499858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743075303730,"sku":"2499858","price":270.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_fd0ddc82-94e6-49d2-9d3c-653ba4e428c9.jpg?v=1788842275","url":"https:\/\/voomisupply.com\/products\/kennametal-2499858-carbide-replaceable-tip-drill-20-24mm","provider":"Voomi Supply","version":"1.0","type":"link"}
