It measures 16.50 mm in diameter with an overall length of 152.00 mm (5.984 inches) and features a 135-degree web-thinned point for accurate self-centering and reduced thrust. The DEX multi-layer coating extends tool life when cutting hard and abrasive materials. With a straight cylindrical shank of 17.00 mm diameter and a regular spiral flute geometry, this bit is built for use in CNC machining centers, drill presses, and production environments where consistent hole quality is required.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for cutting steel, stainless steel, cast iron, and high-temperature alloys in precision manufacturing and metalworking operations. The screw machine length format provides added rigidity compared to jobber-length bits, making it a practical choice for short, accurate holes in production setups. Coolant-through capability supports high-speed drilling cycles where internal chip evacuation and heat management are critical. It is part of the MDW-HGS series, designed for use in applications requiring tight diameter tolerances and reliable performance in difficult-to-machine materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003eDEX multi-layer coating for extended tool life and thermal protection\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned point reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal chip flushing in high-cycle operations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and toolholders\u003c\/li\u003e\n\u003cli\u003eh8 diameter tolerance for consistent fit and repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, and high-temperature alloy workpieces. Part of the Sumitomo MDW-HGS series with a drill bit size range of 13.50 mm to 17.00 mm. Verify spindle toolholder compatibility with the 17.00 mm straight shank before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with CNC or manual drilling equipment. Power down and de-energize the machine spindle before loading or changing tooling. Confirm the toolholder bore matches the 17.00 mm shank diameter and that the bit is seated and secured per the machine manufacturer's clamping specifications. Enable coolant-through flow before beginning the drilling cycle to prevent heat buildup and premature coating wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 16.50 mm (0.6496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 152.00 mm (5.984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 82.50 mm (3.248 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 69.50 mm (2.736 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 61.20 mm (2.409 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 3.42 mm (0.135 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\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DEX Multi-Layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.77 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: 5VHY489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51754882007346,"sku":"5VHY489","price":652.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ca56efb48e8007efd689f0ff98839b_76684fe9-aa38-47a9-895f-90b6604a3da3.jpg?v=1788949508","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy489-screw-machine-drill-bit-16-50mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
