Built to Series MDW-GS specifications, it features a 135-degree drill point angle for self-centering entry and reduced thrust force on hard workpiece materials. The bit carries a dual TiAlCr and TiSi coating that extends tool life at elevated cutting temperatures. At 81 mm overall length with a 41 mm flute length and a 4xD flute-to-diameter ratio, it delivers chip evacuation and rigidity suited to through-hole and blind-hole drilling operations. Licensed HVAC techs, machinists, and toolroom professionals will recognize this geometry as standard for interrupted and continuous cuts in cast iron and steel.\u003c\/p\u003e\u003cp\u003eThe 5UHY182 is rated for primary workpiece materials classified under ISO material codes K and P, covering cast iron and steel. Its straight-cylindrical shank at 6 mm diameter seats directly into standard drill chucks, collet holders, and hydraulic toolholders without adapters. The 135-degree split-point geometry makes it suitable for CNC machining centers, drill presses, and hand-held power tools where precise entry and minimal walking are priorities. Coolant-through capability is not provided on this model, so external flood or mist coolant is recommended when drilling deeper holes or harder alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in metal-cutting applications\u003c\/li\u003e\n\u003cli\u003eTiAlCr and TiSi dual coating for extended tool life at high surface speeds\u003c\/li\u003e\n\u003cli\u003e135-degree drill point angle promotes self-centering and lowers entry thrust force\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 6 mm diameter fits standard collet and chuck toolholding\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports chip flow and reduces torque load\u003c\/li\u003e\n\u003cli\u003eh8 diameter tolerance for consistent fit and repeatable hole size\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metal-cutting operations on cast iron and steel workpieces, consistent with ISO material group codes K and P.

Confirm shank seating depth and runout with a dial indicator before first use, as carbide is brittle and sensitive to lateral shock. Apply external flood or mist coolant when operating at higher feeds and speeds or when drilling deep holes, since this bit does not have internal coolant-through passages. Follow the machine tool manufacturer recommended speeds and feeds for carbide tooling in the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 81 mm (3.189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41 mm (1.6142 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 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\u003eDrill Point Length\u003c\/strong\u003e: 1.24 mm (0.0489 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlCr and TiSi\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\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metal Cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\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: 0.1 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: 5UHY182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51735285956914,"sku":"5UHY182","price":134.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/150912c4331ce8c65543f6dd2e1b5914.jpg?v=1788771509","url":"https:\/\/voomisupply.com\/products\/sumitomo-5uhy182-solid-carbide-jobber-drill-bit-6-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
