Ground to a 135-degree split-point geometry, it delivers fast penetration and self-centering entry without a pilot hole. The bit carries a dual-layer TiAlCr and TiSi coating that resists heat and abrasion at elevated cutting speeds. At 9.5 mm in diameter with a 105 mm overall length and a 58 mm flute length, it is built for through-hole and blind-hole drilling in ferrous materials. Licensed machinists and tool-and-die technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for cutting cast iron and steel, covering primary workpiece material codes K and P. Its 4xD flute-to-diameter ratio makes it well suited for moderate-depth holes in production machining, CNC drilling centers, and manual machine shop applications. The straight-cylindrical shank measures 10 mm in diameter and 45 mm in length, fitting standard drill chucks and collet holders in that bore range. It belongs to the MDW-GS series and targets applications where tool life and hole quality in hard ferrous stock are priorities.\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 ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eDual TiAlCr and TiSi coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4xD flute length ratio supports moderate-depth drilling without excessive chip packing\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves chip evacuation and reduces torque demand\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance ensures consistent fit and hole accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces (material codes K and P) across CNC and manual drilling applications. Compatible with standard drill chucks and collet systems accepting a 10 mm straight-cylindrical shank. Part of the SUMITOMO MDW-GS series, sized within the 9.00 mm to 10.00 mm drill bit diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by qualified machinists familiar with carbide tooling requirements. Secure the shank fully in a properly sized chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Power down and lock out the machine spindle before changing or inspecting the bit. Coolant-through is not supported on this bit, so adequate external coolant or air blast should be used to manage heat during extended cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.5 mm (0.3740 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\u003eMaterial\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\u003eOverall Length\u003c\/strong\u003e: 105 mm (4.134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 58 mm (2.284 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 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 by Diameter Ratio\u003c\/strong\u003e: 4xD\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: 1.97 mm (0.0775 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.15 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: 5UHY217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51737606553906,"sku":"5UHY217","price":187.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5aca512bc2cd00bd7fdb9dc6f1bb02ce.jpg?v=1788791286","url":"https:\/\/voomisupply.com\/products\/sumitomo-5uhy217-solid-carbide-jobber-drill-bit-9-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
