Part of the MDW-GS series, it features a 0.332 inch (Letter Q) diameter with a 135-degree split-point geometry and a tapered web configuration. The straight-cylindrical shank seats securely in standard chucks and collets. At 3.2283 inches overall length with a 1.4173 inch flute length, this stub-length format delivers rigidity and reduced deflection compared to jobber-length bits. Solid carbide construction with a coated finish supports extended tool life when cutting hard or abrasive workpiece materials.\u003c\/p\u003e\u003cp\u003eThe U101122 is suited for drilling cast iron and steel in production machining, maintenance, and repair environments. The screw machine length profile makes it a practical choice for CNC machining centers, turret lathes, and drill presses where short-flute stability matters. A 2xD flute-to-diameter ratio and a maximum drilling depth of 0.9195 inches keep chip evacuation efficient in through-hole and shallow blind-hole operations. No coolant-through capability means it performs best with external coolant application or dry cutting at appropriate feed and speed parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with coated finish for wear resistance in cast iron and steel\u003c\/li\u003e\n\u003cli\u003e135-degree drill point angle reduces walking and thrust force at entry\u003c\/li\u003e\n\u003cli\u003eTapered web design supports aggressive chip formation and efficient flute clearance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length format provides superior rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for precise chuck or collet fit\u003c\/li\u003e\n\u003cli\u003e2xD flute-to-diameter ratio optimized for shallow-depth drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill bit for production and maintenance drilling operations in cast iron and steel workpieces requiring a 0.332 inch hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by machinists and tool-and-die professionals using standard drill chucks, collets, or hydraulic toolholders rated for the shank diameter. Ensure the machine spindle and toolholder are clean and true before seating the shank. Apply appropriate cutting speeds and feed rates for solid carbide tooling in the target workpiece material. External coolant or cutting fluid is recommended where applicable since this bit does not feature coolant-through channels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.332 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.2283 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9195 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: U101122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727179481394,"sku":"U101122","price":173.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b50e7284839ee60db9786bb0d45946d3.jpg?v=1788674381","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101122-solid-carbide-screw-machine-drill-bit-0-332in","provider":"Voomi Supply","version":"1.0","type":"link"}
