It carries a Letter Q designation, corresponding to a decimal diameter of 0.3320 inches, with a 135-degree web-thinned point that reduces thrust and improves chip control at entry. The tool is manufactured from solid carbide and features a DEX multi-layer coating for extended tool life in demanding applications. With a total overall length of 3.9370 inches and a straight cylindrical shank, it fits standard toolholders used in CNC machining centers and screw machine setups. Installation and setup are handled by machinists and tooling technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in steel, stainless steel, cast iron, and high-temperature alloys. The screw machine length format offers a rigid, short-body profile that reduces deflection in tight-clearance fixtures or multi-spindle machines. The coolant-through design channels cutting fluid directly to the cutting edge, supporting higher feed rates and longer tool life in deep-hole operations. It is appropriate for automated production environments where repeatable hole quality and tool longevity are priorities. The MDW-HGS series is engineered for high-speed steel and alloy workpieces where standard HSS tooling falls short.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eDEX multi-layer coating extends tool life and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned point reduces entry thrust and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eScrew machine length body minimizes deflection in close-tolerance and multi-spindle setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with 2 margins for consistent hole finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers, screw machines, and drill presses equipped with straight-shank toolholders accepting a 0.3594-inch shank diameter.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the toolholder bore matches the 0.3594-inch shank diameter and that runout is within acceptable tolerance before running at full feed and speed. Coolant-through setups require the machine spindle to support internal coolant delivery for full benefit of the through-coolant feature.\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 Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 inches\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: DEX Multi-layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.9370 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.1654 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1750 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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-HGS\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: 0.1 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: U101124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738862944562,"sku":"U101124","price":237.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ca56efb48e8007efd689f0ff98839b_a1c1b2ce-4b2b-4acd-ae6b-778fde125e32.jpg?v=1788805744","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101124-drill-bit-letter-q-solid-carbide-0-332","provider":"Voomi Supply","version":"1.0","type":"link"}
