It carries the KC7315 manufacturer grade with a TiAlN coating applied via PVD process, delivering wear resistance and thermal stability under demanding cutting conditions. The drill features a 15.45mm (49\/64 inch, 0.6083 inch decimal) cutting diameter, a 140-degree drill point angle, and a two-flute helical design with two margins. Internal coolant-through passages support both flooded coolant and MQL (minimum quantity lubricant) delivery. Licensed HVAC techs and machinists working with metalcutting operations will find the replaceable tip format reduces insert change time and toolholder cost versus solid drill replacement.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for production drilling in steel and cast iron workpieces in both horizontal and vertical orientations. The HPG insert geometry is rated for inclined-entry and inclined-exit drilling, as well as stacked-plate applications where workpiece transitions would challenge a standard drill geometry. The clamp-style insert holding method and KSEM insert seat size 2 keep the tip secure under interrupted-cut and cross-hole conditions. Typical install environments include CNC machining centers and turning centers running steel and cast iron components in job shop, tier supplier, and production floor settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide KC7315 fine-grain tip with TiAlN PVD coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHPG insert geometry supports inclined exit, inclined entry, and stacked-plate drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force on entry and exit\u003c\/li\u003e\n  \u003cli\u003eTwo-flute helical design with two margins and coolant-through passages for chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003eCompatible with MQL (minimum quantity lubricant) and through-coolant delivery methods\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip design extends toolholder life and lowers per-hole tooling cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM series insert seat size 2 toolholders.

Use the recommended torque wrench and clamp screw specified by the toolholder manufacturer when seating the replaceable tip  -  do not overtighten by feel alone. Ensure coolant ports in the toolholder are clear before assembly when running through-coolant or MQL applications. Inspect the insert seat for chips or contamination before 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: 15.45mm (49\/64 inch, 0.6083 inch)\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: 10.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 13.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3829 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.5169 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 \/ 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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\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\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\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: KSEM0766HPG\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: 0.0287 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: 2499856\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743256674610,"sku":"2499856","price":259.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_21798699-93ea-4190-8410-ecc7f92af552.jpg?v=1788844640","url":"https:\/\/voomisupply.com\/products\/kennametal-2499856-carbide-replaceable-tip-drill-15-45mm","provider":"Voomi Supply","version":"1.0","type":"link"}
