It accepts the SMDT07344MTL-C replaceable carbide tip, which carries a dual-layer TiAlCr and TiSi PVD coating applied through a physical vapor deposition process. The 140-degree included point angle and MTL-C insert geometry are optimized for entry stability and chip control when drilling cast iron and steel. Through-coolant capability supports higher cutting speeds and extended tool life in deep-hole applications. This drill is a component of the SMD modular system, intended for use by machinists and CNC tooling specialists in precision machining operations.\u003c\/p\u003e\n\u003cp\u003eThe U103818 body is suited for use in CNC machining centers running cast iron and steel workpieces, corresponding to ISO material groups K and P. The replaceable tip design reduces tooling cost compared to solid carbide drills by allowing tip replacement without discarding the drill body. The 47\/64-inch diameter and SMD series configuration make it appropriate for production drilling applications where consistent hole quality and cycle time are priorities. Through-coolant delivery directly to the cutting edge supports chip evacuation in blind and through-hole operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSMDT07344MTL-C replaceable carbide tip with TiAlCr and TiSi dual-layer PVD coating\u003c\/li\u003e\n  \u003cli\u003e140-degree included point angle for stable entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eMTL-C insert geometry engineered for cast iron and steel cutting\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design supports chip evacuation and heat management at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eACX70 manufacturer grade optimized for ISO K and P workpiece materials\u003c\/li\u003e\n  \u003cli\u003eModular SMD series construction allows tip replacement without replacing the drill body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SMDT07344MTL-C ACX70 replaceable carbide tip as part of the SMD series modular drill system.

Ensure the replaceable tip is seated fully and secured according to the SMD series assembly procedure before spindle operation. Inspect the drill body bore and seating surfaces for wear or contamination prior to tip installation. Verify through-coolant connections are clear and delivering adequate flow before commencing any drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SMD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACX70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReplaceable Tip Part Number\u003c\/strong\u003e: SMDT07344MTL-C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 47\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: MTL-C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron (ISO K), Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: U103818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51729727324466,"sku":"U103818","price":183.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77e495d50fb45fe64a02bb951336aa5c_eaf92a6a-51c9-4774-84ed-21a0db258334.jpg?v=1788708538","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103818-acx70-carbide-replaceable-tip-drill-47-64","provider":"Voomi Supply","version":"1.0","type":"link"}
