Built from high speed steel with a coated finish, this bit measures 2.10 mm (0.0827 inches) in diameter with an overall length of 44.00 mm (approximately 1.73 inches). The 130-degree faceted point provides aggressive, self-centering penetration suited to steel, stainless steel, aluminum, and aluminum alloy workpieces. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation. Licensed machinists, tool-and-die technicians, and maintenance mechanics rely on this style of bit for work in machine tools and drill presses where stub-length rigidity is required.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are shorter than jobber bits, which increases rigidity and reduces deflection in CNC machining centers, turret lathes, drill presses, and hand-held drilling operations where close-tolerance holes are needed. The OSG 61521 is particularly suited to production drilling in steel and stainless steel, as well as aluminum and aluminum silicate components. Its 5xD flute-to-diameter ratio supports efficient chip removal during deep-relative-to-diameter cuts in the materials listed above.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\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\u003e130-degree faceted drill point for self-centering entry and reduced walking on hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003e2-flute spiral configuration with 5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimal deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for screw machine length drill bit applications in Series 1100; compatible with workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Ensure the drill chuck or collet is properly tightened and the shank is fully seated before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning the cut. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0827 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 44.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 61521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728579395890,"sku":"61521","price":34.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d331e2641c3cb308ea96455b64d75979.jpg?v=1788693576","url":"https:\/\/voomisupply.com\/products\/osg-61521-screw-machine-drill-bit-0-0827in-hss-130","provider":"Voomi Supply","version":"1.0","type":"link"}
