It features a 17\/32 inch (0.5313 inch) diameter, a 135-degree split point, and a straight-cylindrical shank with an h8 diameter tolerance for consistent, accurate fitment in standard chucks and toolholders. The overall length is 5.2756 inches with a flute length of 2.6575 inches. Built from solid carbide throughout, this bit delivers the rigidity and wear resistance required for production drilling in ferrous and stainless materials. Coolant-through capability supports high-speed cycles where chip evacuation and heat management are critical. This tool is intended for use by machinists and CNC tool-room technicians in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe U101199 is suited for drilling cast iron, stainless steel, and carbon steel in both manual and CNC machine tool setups. The screw machine length geometry — shorter than jobber length — provides added rigidity and reduced deflection, making it appropriate for close-tolerance hole production on machining centers, drill presses, and CNC lathes. The MDW-HGS series designation identifies this as part of Sumitomo's high-geometry solid carbide stub drill lineup. Maximum drilling depth is 1.8615 inches, positioning it well for through-holes and shallow blind-holes in production fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust load and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed drilling and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body minimizes deflection in short-reach drilling applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 2 flutes and 2 margins for stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003eh8 shank diameter tolerance ensures consistent seating in precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collet-style toolholders accepting a 0.5469 inch shank diameter. Primary workpiece materials listed by the manufacturer are cast iron, stainless steel, and steel. Compatible with CNC machining centers, knee mills, and drill presses equipped for coolant-through tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine fully powered down and the spindle locked. Secure the shank fully within the chuck or collet to the recommended grip depth before tightening. Verify coolant-through passages are clear and that the machine tool's coolant supply pressure is compatible with the toolholder before running. Solid carbide tooling is brittle — avoid lateral loading or using a worn, out-of-round chuck that could cause chipping at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 17\/32 inch (0.5313 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.2756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.6575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5469 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.8615 inches (47.28 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1100 inch (2.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.5000 to 0.6000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: U101199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51735273701682,"sku":"U101199","price":465.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9a9c9baf064daad4cf3fb44a2b67588.jpg?v=1788771345","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101199-screw-machine-drill-bit-17-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
