Built from solid carbide, it delivers the rigidity and wear resistance needed when drilling cast iron, stainless steel, and carbon steel. The bit features a 135-degree split point, a 9.50 mm diameter, and a tapered web configuration that promotes chip evacuation and reduces walking on entry. Coolant-through capability supports high-speed machining operations where heat management is critical. Machinists and tool-and-die professionals specify this series when cycle time and hole quality both matter.\u003c\/p\u003e\u003cp\u003eThe 5VHY071 belongs to SUMITOMO's MDW-HGS series and is sized for screw machine length applications — a shorter, stiffer geometry suited to CNC machining centers, lathes with live tooling, and production drilling fixtures. Primary workpiece materials include cast iron, stainless steel, and steel. The straight-cylindrical shank fits standard ER and drill chuck toolholding. Maximum drilling depth is 35.30 mm, keeping the application squarely in the short-hole drilling category where rigidity and positional accuracy are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and thermal stability in ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree point angle reduces thrust force and minimizes workpiece deformation on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels cutting fluid directly to the cutting edge for chip flushing and heat control\u003c\/li\u003e\n\u003cli\u003eTapered web configuration improves chip flow through the 47.50 mm flutes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance ensures consistent runout in standard toolholders\u003c\/li\u003e\n\u003cli\u003e2-margin geometry balances hole roundness with reduced friction in the cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and production drilling equipment accepting a straight-cylindrical shank with a 10.00 mm shank diameter.

Ensure the spindle and toolholder are clean and free of chips before seating the shank. Confirm coolant-through passages in the toolholder are aligned and open before running the spindle. Follow machine manufacturer torque specifications for the chuck or collet nut — do not overtighten, as solid carbide shanks are brittle under radial clamp loads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.50 mm (0.3740 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.50 mm (1.8701 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 106 mm (4.1732 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 Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 56.00 mm (2.2047 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.30 mm (1.3898 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.97 mm (0.0775 inches)\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: 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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\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\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\u003ePackage Weight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5VHY071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731468910898,"sku":"5VHY071","price":238.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38eeebf5aea00bb2fa66b4372cac25e7.jpg?v=1788731470","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy071-screw-machine-drill-bit-9-50mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
