It features a 9.00 mm diameter with a straight cylindrical shank of equal 9.00 mm diameter and a 135-degree split-point geometry that reduces walking and improves centering on entry. The drill carries a multi-layer TiAlCr and TiSi proprietary coating that extends tool life when cutting steel, stainless steel, and hardened materials. Overall length is 3.858 inches (98.00 mm) with a flute length of 2.165 inches (55.00 mm). This is a two-flute design with a tapered web configuration, classified as a high-performance grade tool in the MDW-GS series.\u003c\/p\u003e\n\u003cp\u003eThe 5UHY212 is suited for machine-shop, production, and maintenance applications where steel and stainless steel are the primary workpiece materials. The 4xD flute-to-diameter ratio makes it appropriate for moderate-depth through-holes in CNC machining centers, drill presses, and manual mill setups. Its h8 shank diameter tolerance ensures consistent tool holding in standard collet chucks and hydraulic holders. Hardened materials are listed as a supported workpiece category, making this drill a practical option for tool rooms working with treated or alloy steels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiAlCr and TiSi coating for extended tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration enhances chip clearance and point strength\u003c\/li\u003e\n  \u003cli\u003eh8 shank diameter tolerance for precise, repeatable tool holding\u003c\/li\u003e\n  \u003cli\u003e4xD flute ratio supports moderate-depth hole drilling without coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and conventional drilling equipment with standard straight-shank tool holders.

Ensure the tool holder is clean and free of chips before seating the shank, and torque set-screw or collet nut to the holder manufacturer specification. Verify spindle speed and feed rate against the MDW-GS series cutting data for the target workpiece material before engaging the cut. No coolant-through capability is present on this drill; use external flood or mist coolant as appropriate for the material and depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.00 mm (0.3543 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 Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer TiAlCr and TiSi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.858 inches (98.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.165 inches (55.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.00 mm (0.3543 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eDrill Point Length\u003c\/strong\u003e: 0.073 inches (1.86 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 5UHY212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51752238809394,"sku":"5UHY212","price":188.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b6c5141c967477ea14eece0e79f6cf6_2c90fa80-474e-41a8-9190-dc511a142620.jpg?v=1788926840","url":"https:\/\/voomisupply.com\/products\/sumitomo-5uhy212-solid-carbide-jobber-drill-9mm-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
