Built from high speed steel with a coated finish, it measures 0.039 inches (wire size 61, 0.99 mm) in diameter with a 150-degree faceted point angle and a web-thinned, tapered web configuration. The straight-cylindrical shank and regular spiral flute geometry promote clean chip evacuation and consistent cutting. At 38.00 mm overall length, this short-body design provides added rigidity compared to jobber-length bits, reducing deflection in precision drilling applications. Licensed machinists, tool-and-die technicians, and metal fabricators are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate in screw machine and close-tolerance production environments. The screw machine length format is commonly specified when rigidity and positional accuracy are required, such as when drilling from a turret, drill press, or CNC machining center without a pilot. The 5xD flute-to-diameter ratio supports deeper holes relative to bit diameter while maintaining chip clearance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 61 (0.039 inches \/ 0.99 mm) diameter with tight tolerance of +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e150-degree faceted point angle with web thinning for reduced thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute regular spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit for screw machine, drill press, turret, and CNC applications requiring wire size 61 diameter in the OSG Series 1100 product line.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tool operators familiar with speeds-and-feeds selection for the target workpiece material. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Do not exceed the recommended feed rate for the material being drilled, as this bit diameter is susceptible to breakage under excessive lateral load. Coolant-through is not supported on this bit; use external flood or mist coolant as appropriate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.99 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (approximately 1.496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 8595099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746993766706,"sku":"8595099","price":38.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_3586d79a-10ba-457c-bd44-660718f97a61.jpg?v=1788875186","url":"https:\/\/voomisupply.com\/products\/osg-8595099-screw-machine-drill-bit-0-039-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
