It accepts the KSEM0734HPL insert tip, which features a solid carbide construction with an AlTiN (aluminum titanium nitride) PVD coating and HPL insert geometry. The 140-degree included angle point is suited for clean entry and exit in a variety of workpiece materials. The insert is held by a clamp mechanism and fits an insert seat size 2 body. This part is typically procured and installed by machinists and tooling specialists on CNC drilling and machining centers.\u003c\/p\u003e\u003cp\u003eThis drill tip is engineered for use across a broad range of primary workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is rated under ISO material grades P, M, K, N, and S, making it a versatile option for production shops running mixed-material operations. The KSEM series is commonly used in applications involving inclined exit drilling, stacked plate drilling, and standard through-hole operations. The helical, regular spiral flute design with a 2-flute, 2-margin configuration supports chip evacuation in these conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide tip with AlTiN PVD coating for wear resistance in steel, stainless, and superalloy materials\u003c\/li\u003e\n\u003cli\u003e140-degree included angle for controlled entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eHPL insert geometry with 2-flute, 2-margin configuration for chip control\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for repeatable tip seating and replacement\u003c\/li\u003e\n\u003cli\u003eCompatible with inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003cli\u003eKSEM series insert seat size 2 for use with matching KSEM drill bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM series replaceable tip drill bodies accepting insert seat size 2.

Use the manufacturer-specified torque wrench or hex key for the clamp screw to ensure proper tip seating — do not over-tighten by hand. Inspect the insert seat for debris or damage before installing a new tip. Follow applicable shop safety procedures and machine tool manufacturer guidelines during tooling changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Fractional Inch)\u003c\/strong\u003e: 47\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.7343 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 18.65 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, Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3670 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.00 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: 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\u003c\/strong\u003e: AlTiN (PVD Process)\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: 2\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: KSEM0734HPL\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: 3381144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728485056818,"sku":"3381144","price":246.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02b921f43a491ba90ca723f6734e6606.jpg?v=1788691951","url":"https:\/\/voomisupply.com\/products\/kennametal-3381144-ksem-carbide-replaceable-tip-drill-47-64","provider":"Voomi Supply","version":"1.0","type":"link"}
