The drill accepts a solid carbide KSEM1125HPG tip with KC7315 fine-grain grade and a TiAlN PVD coating, delivering wear resistance and thermal stability in demanding ferrous machining applications. The 140-degree included angle and helical flute geometry support chip evacuation, while integrated through-coolant channels are compatible with both flood coolant and minimum quantity lubrication (MQL) delivery. Cutting diameter is 28.58 mm (1.125 inches). This tool is installed and operated by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for drilling operations in steel and cast iron workpieces, including applications involving inclined exits, stacked plates, and through-coolant setups. The KSEM platform uses a clamp-style insert holding method with an insert seat size of 7, providing repeatable tip indexing without full tool replacement. The 2-flute, 2-margin configuration supports both precision and throughput in vertical machining centers and horizontal machining centers running ISO P and ISO K material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide KSEM1125HPG tip with KC7315 fine-grain grade for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal resistance and reduced built-up edge in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle optimized for standard entry and inclined-exit drilling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable with MQL compatibility for flexible coolant strategy\u003c\/li\u003e\n  \u003cli\u003e2-flute helical design with 2 margins for chip control and bore quality\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding with seat size 7 for secure, repeatable tip seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM series replaceable tip drill bodies accepting insert seat size 7 and the HPG insert geometry.

Ensure the insert seat is clean and free of chips before seating the carbide tip, and verify clamp torque using the tooling manufacturer's recommended procedure for KSEM holders. Coolant passages should be confirmed clear before operation when using through-coolant or MQL delivery. Follow applicable shop safety standards and machine tool manufacturer guidelines for toolholder setup and runout verification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 28.58 mm (1.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7315\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\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\u003eSeries\u003c\/strong\u003e: KSEM\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: 7\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: 14.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.5625 inches\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\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\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\u003eISO Number\u003c\/strong\u003e: KSEM1125HPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0816 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: 2499873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743350194482,"sku":"2499873","price":316.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_a0b97e98-4c82-4201-9fe9-77d87a6e2b6d.jpg?v=1788846004","url":"https:\/\/voomisupply.com\/products\/kennametal-2499873-carbide-replaceable-tip-drill-1-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
