It measures 15\/64 inch (0.2344 inch) in diameter with an overall length of 2.5591 inches and a flute length of 1.0630 inches. The 135-degree split point geometry reduces walking and improves entry accuracy on flat or curved surfaces. Solid carbide construction delivers greater rigidity and heat resistance compared to high-speed steel, making it well suited for consistent, repeatable hole production on harder workpiece materials. This bit is sized to h8 diameter tolerance, supporting close-tolerance bore work.\u003c\/p\u003e\n\u003cp\u003eThe U101064 is intended for use in cast iron and steel workpieces, covering a broad range of ferrous machining tasks common in manufacturing, fabrication, and maintenance environments. The screw machine (stub) length format provides added rigidity over jobber-length bits, which reduces deflection during entry and through-feed. It is typically used in CNC machining centers, drill presses, and turret lathes where short-reach tooling is specified. The straight-cylindrical shank is compatible with standard drill chucks and collet holders in the matching shank diameter. Coolant-through capability is not included on this model.\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\u003e135-degree point angle reduces thrust and minimizes drill walk on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format at 2.5591 inches OAL for maximum rigidity\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eh8 diameter tolerance supports close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003e2xD flute-by-diameter ratio with a maximum drilling depth of 0.7116 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the MDW-GS series, the U101064 is designed for drilling cast iron and steel and fits standard drill chucks or collet systems accepting a 0.2344-inch straight-cylindrical shank.

Ensure the spindle is fully stopped and locked out before changing tooling. Secure the shank fully in the chuck or collet and verify runout before engaging the cut. Do not exceed the recommended maximum drilling depth of 0.7116 inches per pass without retracting to clear chips, as this bit does not include coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5591 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0630 inches (1-1\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7116 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: 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: U101064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51736789287218,"sku":"U101064","price":110.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dbdfcca5bd102a5062d4c56c0fa44ad.jpg?v=1788780405","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101064-screw-machine-drill-bit-15-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
