It features a 140-degree included point angle and an MTL insert geometry, delivering consistent, accurate entry and chip formation in demanding machining environments. The TiAlCr\/TiSi dual-layer coating is applied via PVD process, providing high heat resistance and extended edge life at elevated cutting speeds. Through-coolant capability channels fluid directly to the cutting edge, improving chip evacuation and thermal control. This drill is used by machinists and tool-and-die professionals in CNC turning and machining center applications.\u003c\/p\u003e\u003cp\u003eThe U101388 is suited for production drilling in steel workpieces where hole quality and tool life consistency are critical. The replaceable carbide tip design reduces tooling cost by allowing tip replacement without discarding the drill body. The ACX70 grade and MTL geometry are optimized for the P material group, which includes carbon steels, alloy steels, and tool steels. It is a fit for shops running moderate to high spindle speeds with flood or through-spindle coolant delivery systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e140-degree included point angle for aggressive, self-centering entry in steel\u003c\/li\u003e\n\u003cli\u003eACX70 carbide grade with TiAlCr\/TiSi PVD coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eMTL insert geometry optimized for P-group steel workpiece materials\u003c\/li\u003e\n\u003cli\u003eThrough-coolant construction for direct cooling at the cutting edge and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eReplaceable carbide tip design reduces overall tooling cost per hole\u003c\/li\u003e\n\u003cli\u003eSMD Series platform for standardized body and tip interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replaceable tip drill for use with compatible SUMITOMO SMD Series drill bodies accepting the MTL tip geometry at 1-3\/16 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tip changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per facility LOTO procedures. Ensure the drill body taper and seating surfaces are clean and free of chips before seating the replaceable tip. Verify through-coolant connections are properly engaged and coolant pressure is set per machine specifications before running. Follow the drill manufacturer and machine tool builder guidelines for speed and feed parameters when setting up this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 140 degrees\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: ACX70\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: MTL\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P\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: 0.5 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: U101388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51737717145906,"sku":"U101388","price":212.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b977fd6772a73effaeacc91a5410cfb_8f47b458-0874-44d1-9a11-f9ab73a65bc9.jpg?v=1788792698","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101388-carbide-replaceable-tip-drill-acx70-smd","provider":"Voomi Supply","version":"1.0","type":"link"}
