It measures 13\/64 inches (0.2031 inches decimal) in diameter with a 140-degree R-thinned point that reduces thrust and improves centering on entry. The overall length is approximately 2.6 inches (66 mm), making it a compact stub-length tool well suited for close-clearance work. The EgiAs coating adds surface hardness and heat resistance to extend tool life in demanding cuts. Two spiral flutes with a regular helix provide efficient chip evacuation throughout the cut.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for production and maintenance drilling in steel, alloy steel, and cast iron. The screw machine length format — shorter than jobber length — increases rigidity and reduces deflection, which is especially useful in CNC machining centers, drill presses, and turret lathes where tool overhang must be minimized. The straight-cylindrical shank with a 0.25-inch diameter fits standard drill chucks and collet systems without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating improves surface hardness and thermal resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point reduces entry thrust and self-centers on the workpiece\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with R-thinned web reduces cutting force at the chisel edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production drill bit for use in standard drill chucks and collet holders accepting a 0.25-inch straight-cylindrical shank.

Secure the straight shank fully in a drill chuck or collet before operation and verify runout before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and can fracture if the setup has excessive vibration or the tool is improperly supported.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/64 inches (0.2031 inches decimal \/ 5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\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: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.6 inches (66 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 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 Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6300\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: 0.055 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630020211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737153536306,"sku":"630020211","price":131.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cd4befa59ba27f45b8244c9b08d6a86.jpg?v=1788784992","url":"https:\/\/voomisupply.com\/products\/osg-630020211-screw-machine-drill-bit-13-64-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
