Built from solid carbide with a coated finish, this bit measures 0.1969 inches (5.00 mm) in diameter and delivers consistent, accurate hole quality in ferrous materials. The 135-degree split point reduces walking and cutting force at entry, making it well suited for CNC and manual drilling operations. With an overall length of 2.4016 inches and a two-flute design, it provides efficient chip evacuation in short-depth drilling cycles. Licensed machinists and tool-and-die professionals are the primary users of this style of bit.\u003c\/p\u003e\n\u003cp\u003eThe 5UHY031 belongs to the SUMITOMO MDW-GS series and is designed for use on cast iron and steel workpieces. Its screw machine length profile — shorter than a jobber bit — makes it ideal for rigid setups on CNC machining centers, drill presses, and turret lathes where overhang must be minimized. The straight-cylindrical shank fits standard drill chucks and collet toolholders without modification. Maximum drilling depth is 0.6890 inches, appropriate for through-hole and shallow blind-hole work in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces entry walking and thrust force\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in abrasive ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTwo-flute tapered web design promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides enhanced rigidity in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Ensure the spindle is fully stopped and the machine is de-energized before changing tooling. Secure the shank firmly in a properly sized collet or drill chuck to the depth recommended by the toolholder manufacturer. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fail suddenly if run with damaged geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1969 inches (5.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4016 inches (61.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6890 inches (17.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0408 inches (1.04 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.201 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: 5UHY031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51747569795378,"sku":"5UHY031","price":110.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70f383a9371d0cc2056d9a06dee579ba.jpg?v=1788882740","url":"https:\/\/voomisupply.com\/products\/sumitomo-5uhy031-screw-machine-drill-bit-0-1969in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
