Built to Series MDW-HGS specifications, it features a 6.30 mm (0.2480 inch) diameter with a 135-degree web-thinned point that reduces thrust and improves centering on entry. The DEX multi-layer proprietary coating extends tool life in abrasive and heat-generating cuts. Overall length is 88.00 mm (3.46 inches) with a 7.00 mm straight cylindrical shank, making it compatible with standard drill chucks and collet systems. This bit is intended for use by machinists and toolroom professionals in CNC and manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 5VHY039 is suited for drilling steel, stainless steel, cast iron, and high-temperature alloys in production and job-shop environments. Its screw machine length body provides increased rigidity compared to jobber-length bits, reducing deflection in short-reach setups on machining centers, drill presses, and lathes with live tooling. The 3xD flute-to-diameter ratio and tapered web configuration support chip evacuation in interrupted and continuous cuts. Coolant-through capability allows internal coolant delivery directly to the cutting zone, extending tool life in high-speed production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard metalworking materials\u003c\/li\u003e\n  \u003cli\u003eDEX multi-layer coating reduces heat buildup and extends tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e135-degree web-thinned point improves self-centering and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers internal coolant directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 2-flute regular spiral geometry supports controlled chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, and high-temperature alloy workpieces.

Ensure the shank is fully seated and securely clamped in the tool holder before operation, and verify spindle speed and feed rate are set per the machine shop's tooling guidelines for carbide drills in the target material. When using coolant-through capability, confirm that internal coolant channels are clear and supply pressure is adequate before initiating the cut. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fail suddenly if run on worn edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.30 mm (0.2480 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 88.00 mm (3.46 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 53.00 mm (2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 32.50 mm (1.28 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 24.40 mm (0.96 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\u003eDrill Point Length\u003c\/strong\u003e: 1.30 mm (0.05 inches)\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\u003eSpiral Type\u003c\/strong\u003e: Regular\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\/Finish\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temperature Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 0.05 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: 5VHY039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51748744757554,"sku":"5VHY039","price":166.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ca56efb48e8007efd689f0ff98839b_e7cac03b-557f-4a7c-a050-a28a7127b4de.jpg?v=1788897680","url":"https:\/\/voomisupply.com\/products\/sumitomo-5vhy039-screw-machine-drill-bit-6-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
