At 7\/32 inch (0.2188 inches) in diameter, it features a 135-degree split-point angle and a tapered web configuration that promotes self-centering and reduces walking on entry. The MDW-GS series construction uses solid carbide throughout for rigidity and wear resistance. With a straight-cylindrical shank and a compact 2.5591-inch overall length, this bit suits close-tolerance drilling operations where stub-length rigidity is required. It is typically installed by machinists and toolroom technicians in CNC machining centers, drill presses, and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron and steel workpieces in production and maintenance machining environments. The screw machine length (stub) configuration minimizes deflection and improves hole location accuracy compared to jobber-length bits, making it a practical choice for repetitive drilling cycles on hard ferrous materials. The 2xD flute-by-diameter ratio supports chip evacuation in shallow-to-moderate depth holes. It does not include coolant-through capability, so external coolant or cutting fluid application is standard practice with this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle with tapered web for self-centering entry\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for consistent chuck fit\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.5591 inches overall reduces deflection in tight setups\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry with 1.0630-inch flute length optimized for chip clearance\u003c\/li\u003e\n  \u003cli\u003eMDW-GS series coated finish for enhanced surface wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement drill bit for use in standard straight-shank drill chucks and collet holders accepting 7\/32 inch diameter tooling; primary workpiece materials are cast iron and steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the straight-cylindrical shank fully in a drill chuck or collet to the recommended grip depth before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter per machining reference data. Apply external cutting fluid or coolant at the cutting zone, as this bit does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\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\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 Length\u003c\/strong\u003e: 1.0630 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5591 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0453 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\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 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: 0.05 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: U101058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51755203494194,"sku":"U101058","price":110.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c3d3288ae9a04c2d5ff0d61d66e110c.jpg?v=1788952146","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101058-screw-machine-drill-bit-7-32-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
