The tip is manufactured from solid carbide with a fine-grain material grade and coated with TiAlN via a PVD process for wear resistance and thermal stability. The cutting diameter measures 22 millimeters (0.866 inches), the drill point angle is 140 degrees, and the design incorporates 2 flutes with a regular helical spiral. An integrated through-coolant system supports both flood coolant and MQL (Minimum Quantity Lubrication) delivery directly to the cutting zone. This tool is installed and replaced by machinists and CNC tooling technicians in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe 2499779 is suited for drilling operations in steel and cast iron workpieces, corresponding to ISO material groups P and K. The KSEM replaceable tip design allows the carbide insert to be swapped without removing the drill body from the machine, reducing downtime on high-volume production runs. It is engineered to handle demanding drilling scenarios including inclined exit surfaces and stacked plate configurations. The KC7315 manufacturer grade and HPG insert geometry are optimized for these work materials and cutting conditions. The insert seat size is 3, and the tool is secured via a clamp holding method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide tip with TiAlN PVD coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e22mm cutting diameter with 140-degree drill point angle for clean entry and exit\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability supporting both flood and MQL delivery\u003c\/li\u003e\n\u003cli\u003eHelical 2-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCapable of inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003cli\u003eReplaceable tip format reduces tooling cost and changeover time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replaceable tip insert for KSEM series drill bodies accepting insert seat size 3.

Seat and clamping surfaces should be cleaned before seating the new tip to ensure proper seating and runout. Consult the KSEM toolholder documentation for correct clamping torque and coolant connection procedures. Follow the machine tool manufacturer and facility safety guidelines when setting tool offsets after tip replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\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\u003eCutting Diameter\u003c\/strong\u003e: 22 mm (0.866 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\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.433 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.586 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15 mm\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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 Group\u003c\/strong\u003e: P, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 2499779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733372993842,"sku":"2499779","price":271.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_f8da6966-3594-4a44-8df6-f554a80f9e77.jpg?v=1788754842","url":"https:\/\/voomisupply.com\/products\/kennametal-2499779-carbide-replaceable-tip-drill-22mm-ksem","provider":"Voomi Supply","version":"1.0","type":"link"}
