It carries the ISO designation KSEM1125HPL and features a 1-1\/8 inch (28.58 mm) cutting diameter with a 140-degree drill point angle. The tip is manufactured from fine-grain solid carbide with an AlTiN finish applied via PVD coating, delivering elevated hardness and oxidation resistance at the cutting edge. Two helical flutes with a regular spiral promote chip evacuation during drilling cycles. This drill insert is installed and serviced by machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The HPL insert geometry and KSEM seat size 7 interface are built for interrupted-cut stability, including inclined exit drilling and stacked-plate drilling scenarios. The clamp-style insert holding method ensures secure seating during high-feed passes without coolant-through capability, making it appropriate for applications where external coolant delivery is used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain tip with AlTiN PVD coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch (28.58 mm) cutting diameter, 140-degree standard drill point angle\u003c\/li\u003e\n  \u003cli\u003e2-flute helical configuration with 2-margin design for bore accuracy and guidance\u003c\/li\u003e\n  \u003cli\u003eHPL insert geometry rated for inclined exit and stacked-plate drilling\u003c\/li\u003e\n  \u003cli\u003eKSEM series seat size 7 clamp-style holding for rigid, repeatable tip indexing\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replaceable tip for KENNAMETAL KSEM series drill bodies with seat size 7, accepting the HPL insert geometry in the KSEM1125HPL form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this replaceable tip is performed by a machinist or CNC operator with the spindle fully stopped and machine power locked out. The insert seat should be cleaned and inspected before seating the new tip to ensure full contact and proper clamping torque as specified by the KSEM toolholder documentation. Do not exceed the recommended feed and speed parameters for the workpiece material group being machined. External coolant should be directed at the cutting zone when coolant-through is not available.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-1\/8 inch (1.1252 inches \/ 28.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical, Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCMS15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: AlTiN\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: HPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 7\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: No\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\u003eISO Number\u003c\/strong\u003e: KSEM1125HPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Groups\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Drilling, Inclined Exit Drilling, Stacked Plate Drilling\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: 0.1 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: 3381170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730737725746,"sku":"3381170","price":370.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d89f8302be047048afd63357e42aeaa.jpg?v=1788721985","url":"https:\/\/voomisupply.com\/products\/kennametal-3381170-ksem-carbide-replaceable-tip-drill-1-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
