The tip carries an AlCr (aluminum chromium) PVD coating applied under the KC7410 grade, which provides thermal resistance and edge durability at elevated cutting speeds. The drill features a 19.84mm (25\/32 inch) cutting diameter, a 140-degree included point angle, and a two-flute helical design with a standard point and regular spiral. The tip is held in place by a clamp-style insert seat. This part is intended for use by machinists and tooling technicians operating CNC drilling centers or machining centers in production environments.\u003c\/p\u003e\u003cp\u003eThe 3884481 tip is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. Typical applications include standard through-hole and blind-hole drilling, inclined-exit drilling, and stacked-plate drilling operations. The two-flute, two-margin geometry supports stable cutting action in interrupted or transitional entry conditions. This tip mounts to a compatible KSEM series drill body using insert seat size 2 and is sold as a single replaceable tip, allowing body reuse and fast tip changes at the machine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with AlCr PVD coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eKC7410 grade with K15 material grade designation for broad material compatibility\u003c\/li\u003e\n\u003cli\u003e140-degree standard drill point for reduced thrust and accurate hole entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute helical design with two margins for improved hole straightness and stability\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure seating and repeatable tip positioning\u003c\/li\u003e\n\u003cli\u003eRated for inclined-exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip for compatible KSEM series drill bodies using insert seat size 2.

Use the appropriate torque wrench or clamp key specified for the KSEM body to secure the clamp — do not overtighten by hand or use substitute tools. Inspect the insert seat for chips or contamination before seating the new tip. Follow the drill body manufacturer guidelines for run-in procedure when using a fresh tip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 19.84mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 25\/32 inch\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\u003eFlute Length\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight (mm)\u003c\/strong\u003e: 12mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight (Inch)\u003c\/strong\u003e: 25\/64 inch\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: KC7410\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCr\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: HPCCL\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\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM0781HPCCL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\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 Groups\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: 0.022 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: 3884481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731275940146,"sku":"3884481","price":261.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f81ae1f9af70d3dc8481485e79170054_77baa04a-ceaf-44a5-bf38-8ba39d184a48.jpg?v=1788729152","url":"https:\/\/voomisupply.com\/products\/kennametal-3884481-carbide-replaceable-tip-drill-19-84mm","provider":"Voomi Supply","version":"1.0","type":"link"}
