The drill features a 1.5-inch (38.10 mm) cutting diameter, a 140-degree drill point angle, and an HPG insert geometry optimized for chip evacuation and cutting edge stability. The TiAlN coating is applied via PVD process, providing thermal resistance and wear protection during demanding drilling cycles. With two helical flutes and through-coolant capability including MQL support, this drill is built for production environments where tool life and process reliability are priorities.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is used in machining applications targeting steel and cast iron workpieces, corresponding to ISO material groups P and K. Typical applications include through-hole and blind-hole drilling in fabrication shops, job shops, and production machining cells. The KSEM platform supports inclined exit drilling and stacked plate drilling operations, making it suitable for setups that demand consistent performance across varied fixturing and workpiece geometry. It is installed in standard KSEM drill body holders and is suitable for CNC machining centers and turning centers with coolant-through tooling capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5-inch (38.10 mm) cutting diameter with solid carbide tip construction\u003c\/li\u003e\n\u003cli\u003eTiAlN coating via PVD process for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle for accurate entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with 2-margin design for bore quality and stability\u003c\/li\u003e\n\u003cli\u003eThrough-coolant compatible, including MQL (Minimum Quantity Lubrication)\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for repeatable tip indexing and seating\u003c\/li\u003e\n\u003cli\u003eRated for 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 drill bodies accepting insert seat size 10.

Power down and lock out the machine spindle before seating or removing the replaceable tip. Use the appropriate KSEM torque key or clamping tool as specified by KENNAMETAL for the insert seat size to ensure proper tip seating  -  do not overtighten with non-specified tools. Verify coolant channel alignment before resuming operation to maintain through-coolant flow to the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.5 inches (38.10 mm)\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\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: 19.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.854 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 22.00 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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes (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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1676 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: 2499890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743525175602,"sku":"2499890","price":424.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_e365d4df-4736-464a-be1f-65cea86f657b.jpg?v=1788848042","url":"https:\/\/voomisupply.com\/products\/kennametal-2499890-carbide-replaceable-tip-drill-1-5in-ksem","provider":"Voomi Supply","version":"1.0","type":"link"}
