Featuring a 1-inch (25.40 mm) cutting diameter, the drill accepts an HPL insert geometry tip manufactured from solid carbide KCMS15 grade fine-grain material with a PVD-applied AlTiN coating. The 140-degree drill point angle suits flat-bottom entry and inclined exit conditions. With two helical flutes and a clamp-style insert holding method, the body delivers consistent chip evacuation and tip retention across high-volume production runs. Machinists and tooling technicians install this drill in CNC machining centers and turning centers where indexable tip systems reduce per-hole tooling cost versus solid-carbide alternatives.\u003c\/p\u003e\u003cp\u003eThis drill is suited for use in residential and industrial machine shops running production drilling operations in steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. The KSEM platform is designed for applications involving inclined exit surfaces, stacked plates, and standard through-hole drilling. The two-flute, two-margin geometry with standard point type and regular spiral provides stable cutting action across ISO material groups P, M, K, N, and S. It is appropriate for use in any CNC setup where a 1-inch indexable drill with a size-5 insert seat is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch (25.40 mm) cutting diameter with HPL insert geometry for consistent hole quality\u003c\/li\u003e\n\u003cli\u003eSolid carbide KCMS15 fine-grain grade tip with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle compatible with inclined exit and stacked-plate drilling\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with two-margin design for stable, accurate boring in multi-material applications\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure tip retention at elevated feed and speed conditions\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO material groups P, M, K, N, and S — steel through superalloys and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replaceable tip for KSEM-series drill bodies accepting a size-5 insert seat with HPL geometry.

Use the appropriate Torx or hex key specified by the KSEM body manufacturer to seat the clamp securely before resuming cutting operations. Verify insert seat condition and clamp hardware integrity at each tip change. Do not attempt tip changes with the spindle in motion or the machine in cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch (25.40 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\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\u003eFlute Length\u003c\/strong\u003e: 13.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.5 inches\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3381620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731938804018,"sku":"3381620","price":336.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/219a920728f4babe2a7e7725669a32c2.jpg?v=1788736927","url":"https:\/\/voomisupply.com\/products\/kennametal-3381620-ksem-replaceable-tip-drill-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
