The drill accepts the KSEM0875HPG solid carbide tip with a KC7315 fine-grain grade and a PVD-applied TiAlN coating, giving it strong wear resistance and thermal stability. The cutting diameter is 0.8752 inches (22.23 mm) with a 140-degree drill point angle and a standard helical flute geometry. The tip seats in an insert seat size 4 and is held with a clamp-style clamping method. Through-coolant capability, including MQL (minimum quantity lubrication), is built in. Licensed machinists and CNC operators install this drill in machine tool spindles for production drilling in steel and cast iron.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is suited to production environments where insert tip changes are preferred over regrinding solid drills. It supports drilling into flat surfaces, inclined exits, and stacked plates, making it appropriate for aerospace, automotive, and general machining shops. The helical, two-flute, two-margin design promotes chip evacuation and hole finish. The through-coolant channels support both flood coolant and MQL strategies, extending tip life in demanding steel and cast iron operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KSEM0875HPG tip with KC7315 fine-grain grade for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eTiAlN coating applied by PVD process for thermal and oxidation resistance\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with standard helical, two-flute, two-margin geometry\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design supports flood coolant and MQL (minimum quantity lubrication)\u003c\/li\u003e\n\u003cli\u003eReplaceable tip system reduces tooling cost compared to full solid-carbide drills\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\u003eThe KSEM0875HPG tip is compatible with KSEM series drill bodies accepting insert seat size 4.

Power down or e-stop the machine spindle and verify zero-energy state before seating or removing the replaceable tip. Clamp the insert tip to the specified torque as listed in the KENNAMETAL KSEM tooling assembly documentation supplied with the tool body. Verify through-coolant passages are clear and coolant pressure is within the machine tool specification before resuming cutting operations.\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\u003eISO Number\u003c\/strong\u003e: KSEM0875HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.8752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 22.23 mm\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\/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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.4376 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.5916 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough-Coolant\u003c\/strong\u003e: Yes (flood and MQL)\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0419 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: 2499862\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740025618738,"sku":"2499862","price":265.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ccf094fcca78de618f033c3ebf55006.jpg?v=1788821573","url":"https:\/\/voomisupply.com\/products\/kennametal-2499862-carbide-replaceable-tip-drill-7-8-in-ksem","provider":"Voomi Supply","version":"1.0","type":"link"}
