The solid carbide tip carries an AlTiN coating applied via PVD process, delivering heat and wear resistance needed in production environments. The tip features a 140-degree included angle with HPL insert geometry and a helical, 2-flute, 2-margin configuration. The cutting diameter is 24mm (0.9449 inches), with a flute length of 12mm and an overall projection of 0.6105 inches. The replaceable tip design allows worn or damaged tips to be swapped at the machine without scrapping the full drill body, reducing tooling cost per hole over the life of the holder. Licensed machinists, CNC operators, and toolroom technicians are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for through-hole and blind-hole applications on a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The HPL geometry and fine-grain carbide grade KCMS15 support use in inclined-exit conditions and stacked-plate drilling scenarios where tip geometry and edge stability are critical. It is well-suited to CNC machining centers and multi-axis machines running production runs on structural, aerospace, and general industrial components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide tip with AlTiN PVD coating for extended wear life in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle and HPL insert geometry for stable entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eHelical 2-flute, 2-margin design supports chip evacuation and hole quality\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip system (insert seat size 4, clamp-held) reduces per-hole tooling cost compared to indexable inserts\u003c\/li\u003e\n  \u003cli\u003eRated for inclined-exit and stacked-plate drilling applications\u003c\/li\u003e\n  \u003cli\u003eFine-grain carbide grade KCMS15 for toughness in interrupted and variable-stock conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible KSEM series drill bodies that accept insert seat size 4.

Ensure the insert seat is clean and free of chips or burrs before seating the tip, as contamination can cause runout and premature tip failure. Always confirm proper seating and clamping torque per the toolholder manufacturer's specification before initiating a cut. Coolant-through capability is not available on this tip; verify coolant delivery method is compatible with the intended application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 24mm (0.9449 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\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: KCMS15\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: 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: 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\u003eFlute Length\u003c\/strong\u003e: 12mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.4725 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.6105 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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 Codes\u003c\/strong\u003e: P, M, K, N, S\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: 3381191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746737750322,"sku":"3381191","price":313.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a39b3541519df6498380c7bd88dae52_89aed782-1663-4049-8d1f-9831a9c95ac1.jpg?v=1788873243","url":"https:\/\/voomisupply.com\/products\/kennametal-3381191-carbide-replaceable-tip-drill-24mm-ksem","provider":"Voomi Supply","version":"1.0","type":"link"}
