With a 0.182 inch (4.62 mm) diameter and a 135-degree split-point angle, this bit delivers accurate starts without center-punching on most materials. The two-flute, tapered-web construction evacuates chips efficiently and maintains rigidity in short-length drilling setups. At 2.4016 inches overall length with a 0.9843 inch flute length, the compact screw machine format fits standard drill chucks and CNC turret setups. Diameter tolerance is held to h8, making it suitable for close-tolerance bore work. This bit does not support coolant-through delivery.\u003c\/p\u003e\u003cp\u003eThe U101040 is intended for drilling cast iron and steel in production and job-shop environments. Its screw machine length profile makes it well-suited for turret lathes, CNC machining centers, and drill presses where rigidity and minimal overhang are required. The straight-cylindrical shank accepts standard collets and drill chucks without modification. Maximum drilling depth is 0.7114 inches (18.07 mm), consistent with the 2xD flute-by-diameter ratio of the MDW-GS series. Machinists and tool-and-die professionals working with ferrous materials will find this bit performs reliably across repetitive drilling cycles.\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\u003e135-degree drill point angle for self-centering entry without center-punching\u003c\/li\u003e\n\u003cli\u003eTwo-flute, tapered-web design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eh8 diameter tolerance for close-tolerance and precision bore applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eScrew machine length format reduces overhang for improved rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with cast iron and steel workpieces.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify runout and chuck concentricity before beginning a drilling cycle to protect the carbide cutting edge. Carbide tooling is brittle and should not be dropped or subjected to lateral impact loads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.182 inches (4.62 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9843 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7114 inches (18.07 mm)\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: 0.0378 inches (0.96 mm)\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\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, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MDW-GS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches (3.50 to 5.00 mm)\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: U101040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51752076673330,"sku":"U101040","price":110.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d05048c43eeb7c1712363e131607dab0.jpg?v=1788925679","url":"https:\/\/voomisupply.com\/products\/sumitomo-u101040-screw-machine-drill-bit-0-182-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
