It measures 1.50 mm (0.0591 inches) in diameter with a 135-degree drill point angle, a straight-cylindrical shank, and a maximum drilling depth of 0.3189 inches. The two-flute, coated carbide construction supports coolant-through capability, helping to clear chips and manage heat during deep or high-cycle drilling operations. Machinists and tool-and-die technicians working on CNC and screw machine setups will find this bit suited for tight-tolerance production work where consistent hole quality is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in cast iron, stainless steel, and steel workpieces. The screw machine length format — shorter overall length than jobber bits — provides increased rigidity, which reduces deflection and improves hole location accuracy in production environments. With an overall length of 2.4803 inches and a flute length of 0.3937 inches, it fits standard toolholders accepting a 3.00 mm (0.1181 inch) straight-cylindrical shank. The MDW-HGS series designation indicates a tapered web configuration with a single margin, optimized for hole-entry stability in hard and abrasive materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous metals\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design assists chip evacuation and temperature control\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point geometry reduces walking and thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eTapered web with single margin improves stability in cast iron and stainless steel\u003c\/li\u003e\n  \u003cli\u003eScrew machine length provides extra rigidity for close-tolerance hole positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, screw machines, and drill presses accepting a 3.00 mm straight-cylindrical shank.

Ensure the tool holder and collet are clean and true before seating the shank to avoid runout. Confirm that coolant-through supply is active before beginning the drilling cycle, as dry running can damage the carbide substrate. Handle carbide drill bits with care — they are brittle and can chip if dropped or impacted against hard surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.50 mm (0.0591 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.10 mm (0.3189 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 mm (2.4803 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 50.00 mm (1.9685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 1\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\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 Point Length\u003c\/strong\u003e: 0.30 mm (0.0118 inches)\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\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: 5VHY409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731737805106,"sku":"5VHY409","price":145.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5350259a0f51bc6116deb921412cc24.jpg?v=1788734383","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy409-screw-machine-drill-bit-0-0591-in","provider":"Voomi Supply","version":"1.0","type":"link"}
