It features a 19mm (0.7480 inch) cutting diameter with a 140-degree included angle and a solid carbide tip in the MEL insert geometry. The ACX80 grade tip carries a PVD-applied dual-layer TiAlCr and TiSi coating for thermal resistance and extended tool life. Through-coolant capability channels fluid directly to the cutting edge, managing heat and chip evacuation at the tip. Licensed HVAC techs and machinists in metalworking, aerospace, and general manufacturing environments specify this drill for demanding drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 5KHZ234 is rated for universal primary workpiece materials with material codes K, M, P, and S, covering cast iron, stainless steel, steel, and heat-resistant superalloys. The SMD replaceable tip platform allows the carbide tip to be swapped without replacing the full drill body, reducing per-hole tooling cost in production environments. Typical applications include through-hole and blind-hole drilling in CNC machining centers where consistent bore diameter and finish are required across high part volumes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide MEL-geometry replaceable tip in ACX80 grade for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlCr and TiSi dual-layer coating for heat resistance and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle optimized for centering accuracy and chip-forming performance\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid to the cutting zone for chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across K, M, P, and S workpiece material codes\u003c\/li\u003e\n  \u003cli\u003eSMD series replaceable tip platform reduces tooling cost versus solid integral drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replaceable tip for SMD series drill bodies accepting the MEL tip geometry at 19mm cutting diameter.

Ensure the drill body bore and tip seating surfaces are clean and free of chips before seating the carbide tip. Follow the machine tool manufacturer and tooling manufacturer torque specifications for the clamping screw when mounting the replaceable tip. Through-coolant connections should be verified for proper sealing before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 19mm (0.7480 inches)\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\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\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\u003eThrough Coolant\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5KHZ234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728831217970,"sku":"5KHZ234","price":141.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_656104a8-4c9d-4a8b-8ce1-59972fde81b9.jpg?v=1788696553","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz234-carbide-replaceable-tip-drill-19mm-acx80","provider":"Voomi Supply","version":"1.0","type":"link"}
