It features a 0.9843 inch (25.00 mm) cutting diameter and is manufactured from solid carbide with a PVD-applied TiAlCr and TiSi dual-layer coating. The MEL insert geometry and 140-degree included angle support efficient chip formation across a wide range of workpiece materials. Coolant-through capability delivers cutting fluid directly to the cutting edge, reducing heat buildup and extending tool life. This tip is installed and changed by machinists and tooling technicians on CNC turning and machining center setups.\u003c\/p\u003e\u003cp\u003eThe 5KHZ274 carries a universal primary workpiece material classification, covering material codes K, M, P, and S — making it suitable for cast iron, stainless steel, carbon steel, and heat-resistant superalloys. It is suited for production drilling applications in aerospace, automotive, and general machining environments where consistent hole quality and tool change efficiency are priorities. The replaceable tip design allows worn tips to be swapped without removing the drill body from the spindle, reducing downtime during high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.9843 inch (25.00 mm) cutting diameter in the SMD series modular drill system\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiAlCr and TiSi dual-layer coating (Grade ACX80)\u003c\/li\u003e\n\u003cli\u003eMEL insert geometry with 140-degree included angle for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels cutting fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material rating covers K, M, P, and S material codes\u003c\/li\u003e\n\u003cli\u003eReplaceable tip format minimizes changeover time on the machine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SUMITOMO SMD-series modular drill bodies accepting the MEL replaceable tip format at 25.00 mm diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eReplaceable drill tips in the SMD series are installed by tooling technicians or machinists following the drill body manufacturer torque and seating procedure documented in the tooling manual. Ensure the drill body interface is clean and free of chips or debris before seating the tip. Confirm coolant-through passages are clear and unobstructed prior to operation. Do not run the tip without the drill body fully secured in the tool holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 0.9843 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 25.00 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: ACX80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SMD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiAlCr and TiSi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: MEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (K, M, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5KHZ274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727294038322,"sku":"5KHZ274","price":189.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_d7938e7b-6f23-4db4-a4e3-f5fb472f8d24.jpg?v=1788675969","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz274-replaceable-drill-tip-acx80-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
