Built from solid carbide, this bit features a 135-degree split point angle that reduces walking and allows for fast penetration without a center punch. It carries a wire gauge size of 7, corresponding to a decimal diameter of 0.2010 inches, and an overall length of 3.2283 inches. The straight-cylindrical shank measures 0.2344 inches in diameter, making it compatible with standard drill chucks and toolholders. Coolant-through construction supports high-speed machining cycles. Machinists, tool and die technicians, and CNC operators in production environments are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThe U101050 is designed for drilling into cast iron, stainless steel, and steel. Its screw machine length profile — shorter than a jobber length bit — provides added rigidity and reduced deflection, which is especially valuable in CNC machining centers, drill presses, and turret lathes where hole location accuracy is critical. The MDW-HGS series designation indicates a high-geometry split-point design with a tapered web configuration and two margins, optimized for chip evacuation and hole finish quality in ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for wear resistance in ferrous and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates walking on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed drilling and extended tool life\u003c\/li\u003e\n\u003cli\u003eTapered web with two margins for improved chip flow and hole finish\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity and reduced deflection versus jobber length\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance h8 for consistent fit in close-tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit for machining operations involving cast iron, stainless steel, and steel workpieces.

Ensure the spindle and toolholder are clean and free of runout before seating the shank. Power down and de-energize the machine before changing tooling. Do not exceed manufacturer-recommended feed and speed parameters for the workpiece material, as carbide tooling is brittle and susceptible to fracture under shock loading or improper chip evacuation conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2010 inches\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: 1.0827 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2344 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0866 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0416 inches\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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, 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\u003eWeight\u003c\/strong\u003e: 0.05 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: U101050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730967494962,"sku":"U101050","price":149.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab5a7fed8664bbdec33a766868a5ac7e.jpg?v=1788725450","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101050-screw-machine-drill-bit-size-7-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
