The drill tip carries the ISO designation KSEM0781HPL and is manufactured to a fine grain carbide grade (KCMS15) with a PVD-applied AlTiN coating for heat resistance and extended tool life. The cutting diameter is 25\/32 inch (0.7810 inches \/ 19.84 mm), and the drill features a 140-degree included point angle with a standard point type. Two helical flutes provide chip evacuation, and the tip is secured by a clamp-style holding method. Licensed HVAC, plumbing, or industrial maintenance technicians working in precision environments will find this tip suitable for high-repeatability drilling cycles.\u003c\/p\u003e\u003cp\u003eThe KSEM0781HPL tip is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (ISO material groups P, M, K, N, and S). Typical applications include through-hole drilling, inclined-exit drilling, and stacked-plate drilling. The helical, regular-spiral flute geometry with a 2-flute, 2-margin configuration supports consistent chip flow and hole quality across these workpiece materials. The flute length is 10.00 mm and the functional length is 0.3905 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KSEM replaceable tip — ISO designation KSEM0781HPL, insert seat size 2\u003c\/li\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for elevated-temperature wear resistance\u003c\/li\u003e\n\u003cli\u003eFine grain carbide substrate, manufacturer grade KCMS15, for toughness in interrupted cuts\u003c\/li\u003e\n\u003cli\u003e140-degree included drill point angle with standard point type\u003c\/li\u003e\n\u003cli\u003e2-flute, 2-margin helical geometry supports inclined-exit and stacked-plate drilling\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure tip retention under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip insert for KSEM series drill bodies accepting insert seat size 2.

Ensure the drill body spindle is fully stopped and the machine is locked out before seating or removing the tip. Inspect the insert seat for chips, debris, or wear before each tip change. Do not exceed the recommended speed and feed parameters for the specific workpiece material and drill body in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 25\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.7810 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 19.84 mm\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: KSEM0781HPL\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\u003eIncluded 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: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3905 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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\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: 0.1 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: 3381156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734279323954,"sku":"3381156","price":285.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ae4e27cc64fed774277f5e2c5c44935.jpg?v=1788762209","url":"https:\/\/voomisupply.com\/products\/kennametal-3381156-carbide-replaceable-tip-drill-ksem","provider":"Voomi Supply","version":"1.0","type":"link"}
