It measures 0.4134 inches (10.50 mm) in diameter with an overall length of 4.5669 inches (116.00 mm). The bit features a 135-degree split point angle, two flutes, and a tapered web configuration that reduces thrust and improves chip evacuation. Coolant-through capability allows internal coolant delivery directly to the cutting zone, extending tool life in deep-hole and high-speed drilling operations. The straight-cylindrical shank measures 11.00 mm in diameter and 2.4016 inches in length, providing stable clamping in standard drill chucks and collet systems.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for use in machining operations involving cast iron, stainless steel, and steel workpieces. The screw machine length format — shorter than jobber length — provides added rigidity and reduced deflection, making it well suited for CNC machining centers, drill presses, and manual milling operations where hole accuracy and repeatability are critical. The MDW-HGS series designation identifies this as a coated carbide drill optimized for production-level drilling in ferrous materials. It is sold individually and is appropriate for machine shops, tool cribs, and maintenance facilities running ferrous metal fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree drill point angle reduces walking and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eTapered web configuration improves chip flow and lowers axial cutting force\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides greater stiffness compared to jobber-length drills\u003c\/li\u003e\n\u003cli\u003eTwo margins and two flutes for balanced cutting and consistent hole geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron, stainless steel, and steel workpieces. Compatible with machine tool spindles and toolholders accepting a straight-cylindrical shank with an 11.00 mm shank diameter.

Ensure the machine spindle is fully powered down and locked out before mounting or removing the drill bit. Secure the straight-cylindrical shank fully within the collet or chuck to the recommended grip depth to prevent pullout under load. When running coolant-through tooling, verify the machine spindle and toolholder assembly support internal coolant delivery before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4134 inches (10.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5669 inches (116.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0669 inches (52.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5354 inches (39.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.4016 inches (61.00 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\u003eDrill Point Length\u003c\/strong\u003e: 0.0856 inches (2.17 mm)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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 Bit Size Range\u003c\/strong\u003e: 0.4000 to 0.4500 inches (9.50 to 11.00 mm)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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, Stainless Steel, Steel\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-HGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: 5VHY081\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730142396722,"sku":"5VHY081","price":320.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cb5f8d710e125f909c9703b9c82ad0c.jpg?v=1788712478","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy081-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
