It carries a 17.00 mm (0.6693 inches) diameter, a 135-degree split-point tip, and a coated finish that extends tool life under demanding cutting conditions. The straight-cylindrical shank seats securely in standard drill chucks and toolholders. Part of the MDW-HGS series, this bit features a tapered web configuration and coolant-through capability, making it well suited for precision production drilling where chip evacuation and heat control are critical. Machinists, toolroom operators, and CNC setup techs are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThe 5VHY494 is intended for drilling cast iron, stainless steel, and steel in both job-shop and production environments. Its screw machine length profile — 5.9843 inches overall with a 3.3465-inch flute length — keeps the tool rigid and minimizes deflection in short-reach setups. The 3xD flute-to-diameter ratio and maximum drilling depth of 2.4803 inches make it appropriate for shallow to mid-depth bores where rigidity and hole quality are priorities. It is typically run on CNC machining centers, drill presses, and turret lathes where coolant-through supply is available.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides hardness and wear resistance for ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels fluid directly to the cutting edge for heat management and chip evacuation\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 2 margins supports accurate, clean hole geometry\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance ensures consistent fit and repeatable hole sizing\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends service intervals between resharpening or replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drilling cast iron, stainless steel, and steel workpieces.

Confirm the toolholder or chuck is rated for the shank diameter and that runout is within acceptable limits before starting a cut. When using the coolant-through feature, verify that the machine spindle coolant supply pressure and flow rate are compatible with the drill requirements. Follow applicable shop safety procedures and machine manufacturer guidelines during setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.6693 inches (17.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.9843 inches (152.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.3465 inches (85.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.4803 inches (63.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.6693 inches (17.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1386 inches (3.52 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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\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: 0.85 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: 5VHY494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730537578802,"sku":"5VHY494","price":887.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58503d5458c5f3bd6b1d5e65fd575f41.jpg?v=1788719194","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy494-screw-machine-drill-bit-0-6693-in","provider":"Voomi Supply","version":"1.0","type":"link"}
