Built from solid carbide with a coated finish, this bit delivers the wear resistance and edge retention required in production machining environments. It measures 0.2953 inches (7.50 mm) in diameter with an overall length of 3.0709 inches (78.00 mm). The 135-degree drill point angle reduces thrust force and improves centering accuracy on hard materials. With two flutes and a tapered web configuration, it clears chips efficiently in short-depth drilling cycles. Licensed machinists and CNC operators are the typical end users for this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use on CNC machining centers, drill presses, and automated production lines where short, rigid tooling is required. The screw machine length profile provides added stiffness compared to jobber-length bits, making it well matched for drilling cast iron and steel workpieces in tight fixture setups or close-tolerance applications. The straight-cylindrical shank with an 8.00 mm (0.3150 inch) diameter seats securely in standard collet chucks and drill chucks within the compatible size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers drilling thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine length design provides rigidity in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration supports efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck systems\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance ensures consistent, repeatable fit in tight-tolerance bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in applications requiring a drill bit in the 0.2500 to 0.3000 inch (6.50 to 8.00 mm) diameter range.

Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation. Follow the machine tool manufacturer guidelines for speed and feed rates appropriate to carbide tooling in ferrous materials. Inspect the cutting edge for chips or wear before each use and replace if the edge is damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2953 inches (7.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0709 inches (78.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.2992 inches (33.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6929 inches (43.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8563 inches (21.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0612 inches (1.55 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Bit Diameter 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 5UHY056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728822731058,"sku":"5UHY056","price":105.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2ee6e314f3a0c525ecb7ee02edb8a3b.jpg?v=1788696434","url":"https:\/\/voomisupply.com\/products\/sumitomo-5uhy056-screw-machine-drill-bit-0-2953-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
