Built around the SMDT3000MEL insert geometry with ACX80 grade solid carbide, this drill features a 30mm cutting diameter and a 140-degree included angle. A PVD-applied TiAlCr and TiSi dual coating provides thermal resistance and extended edge life. Through-coolant capability allows cutting fluid to reach the tip directly, supporting chip evacuation and heat control at depth. Licensed machinists and CNC operators in production and job-shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for machining centers running universal workpiece materials across multiple material categories including cast iron, stainless steel, carbon and alloy steels, and high-temperature alloys, reflected by the multi-code classification K, M, P, and S. The replaceable tip design reduces tooling cost by allowing tip exchange without discarding the body, making it a practical choice for high-volume drilling operations where consistent hole quality and cycle time are priorities. The SMD Series platform is a common fit in automated and semi-automated CNC drilling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30mm cutting diameter with 1.1811-inch decimal equivalent\u003c\/li\u003e\n  \u003cli\u003eACX80 grade solid carbide tip for extended tool life on demanding materials\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlCr and TiSi dual coating for thermal stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle optimized for clean entry and centering\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant construction for direct chip evacuation and tip cooling\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip design reduces per-hole tooling cost compared to solid-body drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SUMITOMO SMD Series replaceable tip drill bodies accepting the MEL insert geometry in 30mm diameter.

Follow the tool body manufacturer torque guidelines for tip clamping — do not over-tighten by hand estimation. Confirm coolant ports are clear and through-coolant pressure is within the machine and tool body specifications before running. Inspect the tip seat for damage or debris before each tip installation to prevent seating errors that could affect hole position and finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 30mm (1.1811 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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlCr and TiSi\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\u003eCoolant Through\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: 5KHZ284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51733673607474,"sku":"5KHZ284","price":212.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_07f9637e-336f-406a-b0c8-2d48221c52b3.jpg?v=1788757901","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz284-carbide-replaceable-tip-drill-30mm","provider":"Voomi Supply","version":"1.0","type":"link"}
