It accepts an SMDT1900MTL-C tip with an ACX70 grade solid carbide insert geometry and a dual PVD coating of TiAlCr and TiSi for extended wear resistance and thermal stability. The 140-degree included point angle suits general-purpose drilling in cast iron and steel. Through-coolant capability delivers cutting fluid directly to the cutting edge, reducing heat buildup and chip evacuation problems in deep-hole applications. Licensed machinists and CNC operators install and use this tool in production machining environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for machining cast iron and steel workpieces across both production and job-shop settings. The MTL-C insert geometry is optimized for stable entry and chip control in these materials, making it a practical choice for horizontal machining centers, vertical mills, and CNC turning centers equipped with through-spindle coolant. The 19mm drilling diameter positions it for medium-bore work in structural, automotive, and general industrial applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eACX70 grade solid carbide replaceable tip for long tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eDual PVD coating — TiAlCr and TiSi — for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree included point angle for stable, general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design reduces heat and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMTL-C insert geometry engineered for cast iron and steel chip control\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip design reduces tooling cost versus solid-body drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SMD series drill bodies accepting the SMDT1900MTL-C replaceable tip.

Ensure the drill body and tip seating surfaces are clean and free of chips before seating the replaceable tip. Through-coolant passages should be verified clear before operation. Follow the machine tool manufacturer and SUMITOMO tooling guidelines for proper clamping torque and runout verification before cutting.\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\u003eTip Part Number\u003c\/strong\u003e: SMDT1900MTL-C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrilling Diameter\u003c\/strong\u003e: 19mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACX70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: MTL-C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlCr \/ TiSi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: Cast Iron, Steel\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: U103766\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51744830816562,"sku":"U103766","price":183.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77e495d50fb45fe64a02bb951336aa5c_255daea1-923e-4f5b-b5d5-c70dd0cd3de4.jpg?v=1788861152","url":"https:\/\/voomisupply.com\/products\/sumitomo-u103766-carbide-replaceable-tip-drill-19mm-acx70","provider":"Voomi Supply","version":"1.0","type":"link"}
