The cutting tip measures 20mm (0.7874 inches) in diameter and features an AlTiN PVD coating applied over a fine-grain solid carbide substrate. The 140-degree drill point angle and helical, regular-spiral flute geometry support stable entry and efficient chip evacuation. The HPL insert geometry and size-3 seat are clamped mechanically, allowing tip replacement without disturbing the drill body. This tool is intended for use by machinists and tooling professionals in production environments.\u003c\/p\u003e\u003cp\u003eThis drill is suited for applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The KSEM series design supports inclined exit drilling and stacked-plate drilling in addition to standard through-hole operations. With a 2-flute, 2-margin configuration and a flute length of 10mm, it is optimized for short-to-medium depth drilling where rigidity and surface finish quality are priorities. Typical use cases include production drilling on CNC machining centers and drill presses in metal fabrication and aerospace component manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20mm cutting diameter (0.7874 inches) with 140-degree included point angle for clean entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eSolid carbide fine-grain tip with AlTiN PVD coating for wear resistance across hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eHPL insert geometry on a size-3 KSEM seat, clamped mechanically for repeatable tip indexing\u003c\/li\u003e\n\u003cli\u003e2-flute, 2-margin helical flute design supports chip control and hole roundness\u003c\/li\u003e\n\u003cli\u003eCompatible with inclined exit and stacked-plate drilling applications per KSEM series application data\u003c\/li\u003e\n\u003cli\u003eReplaceable-tip design reduces tooling cost by allowing body reuse after tip wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM series drill bodies accepting a size-3 insert seat.

Ensure the machine spindle is fully stopped and locked out before changing the cutting tip. Inspect the insert seat and clamping screw for wear or debris before seating a new tip. Follow the machining center manufacturer's recommendations for speed and feed parameters based on workpiece material and depth-to-diameter ratio.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 20mm (0.7874 inches)\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, Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.5067 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 13mm\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\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: 3\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\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\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: 3381157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730767675698,"sku":"3381157","price":284.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a39b3541519df6498380c7bd88dae52.jpg?v=1788722528","url":"https:\/\/voomisupply.com\/products\/kennametal-3381157-carbide-replaceable-tip-drill-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
