Built from solid carbide, it delivers the rigidity and wear resistance required when drilling cast iron, stainless steel, and steel. The bit features a 135-degree split-point geometry that reduces walking on entry and lowers thrust force across the cut. At 2.8346 inches overall length with a flute length of 0.8858 inches, the compact stub format is optimized for stiffness in short-reach drilling setups. Coolant-through design supports high-speed operation and chip evacuation in production environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for CNC machining centers, drill presses, and automated production cells where screw machine length tooling is specified. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Primary workpiece materials include cast iron, stainless steel, and steel, making it appropriate for general metalworking, fabrication shops, and maintenance machining operations. The MDW-HGS series designation indicates this is part of a high-performance carbide stub drill line intended for controlled, coolant-fed drilling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and thermal resistance in metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces thrust and minimizes entry walking\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and heat management at depth\u003c\/li\u003e\n  \u003cli\u003eScrew machine length format provides added stiffness versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 2 flutes and 2 margins for accurate hole geometry\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance on shank ensures consistent chuck or collet fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style production drill in the SUMITOMO MDW-HGS series, suitable for straight-shank drill chucks and collet toolholders accepting a 0.1562-inch shank diameter.

Before tool changes, de-energize the machine spindle and confirm the tool is fully secured in the chuck or collet to the specified gripping depth. Carbide tooling is brittle and should not be subjected to lateral shock or interrupted cuts beyond the tool's rated application. Always verify coolant flow is active before initiating a drilling cycle when using the through-coolant feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.8346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8858 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8898 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6515 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0326 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: U101028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51746514272562,"sku":"U101028","price":145.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17ec46d28a52448882cb5963a3c52cd9.jpg?v=1788870961","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101028-screw-machine-drill-bit-5-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
