It carries a 4.20 mm (0.1654 inch) diameter with a 135-degree split-point tip geometry and a tapered web configuration for improved chip evacuation and reduced thrust. The straight-cylindrical shank measures 5.00 mm in diameter and 2.0866 inches in length, fitting standard drill chucks and collet holders. Coolant-through capability supports internal flood or mist cooling during high-speed operations. This bit is designed for use by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 5VHY018 is suited for drilling cast iron, stainless steel, and steel in screw machine, CNC lathe, and machining center setups. The screw machine length design provides a shorter, more rigid profile compared to jobber-length bits, reducing deflection during entry and improving positional accuracy in tight-tolerance work. The MDW-HGS series designation indicates a high-geometry, coated carbide design optimized for interrupted cuts and work-hardening alloys common in production machining. Maximum drilling depth is 0.7717 inches (19.60 mm), suited for shallow-to-moderate depth holes in the primary workpiece materials listed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with applied coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree drill point angle reduces thrust and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal cooling for high-speed and deep-hole operations\u003c\/li\u003e\n\u003cli\u003eTapered web with 2-flute, 2-margin geometry promotes chip flow and hole-wall finish\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides a rigid, compact profile for accurate drilling in production setups\u003c\/li\u003e\n\u003cli\u003eh8 diameter tolerance ensures consistent fit in precision toolholders and bushings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with cast iron, stainless steel, and carbon steel workpieces. Part of the SUMITOMO MDW-HGS series. Compatible with standard 5.00 mm straight-cylindrical shank toolholders, collet chucks, and drill bushings in CNC machining centers and screw machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle at a complete stop and machine power locked out. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder specification before cycling the machine. Verify coolant-through passages are clear and supply pressure is adequate before engaging the cut. Do not exceed the maximum drilling depth of 0.7717 inches without a peck-drilling cycle to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80.00 mm (3.1496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25.00 mm (0.9843 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 19.60 mm (0.7717 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.87 mm (0.0342 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches (3.50 to 5.00 mm)\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: 0.18 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: 5VHY018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728214950194,"sku":"5VHY018","price":114.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c70108944ef0a417928c0a910e9af724.jpg?v=1788689678","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy018-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
