Built from high speed steel with a coated finish, it measures 1.10 mm (0.0433 inches) in diameter and features a 140-degree faceted point angle with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard drill chucks and collets. At an overall length of 39.00 mm and a flute length of 7.00 mm, the compact geometry minimizes deflection and is well suited to CNC machining centers, drill presses, and screw machine operations requiring tight tolerances.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for high performance cutting in a range of materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The Series 1100 designation indicates an OSG screw machine length product line optimized for short-reach, high-accuracy work. The 2-flute regular spiral configuration promotes efficient chip evacuation in both ferrous and non-ferrous materials. Typical applications include production drilling in job shops, machine shops, and automated machining environments where consistent hole quality at small diameters is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.10 mm (0.0433 inches) diameter with a diameter tolerance of +0 to -0.014 mm for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e140-degree faceted point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine length (5xD flute-to-diameter ratio) provides superior rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight hand cut, 2-flute spiral configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks, collets, and screw machine spindles accepting a 3.00 mm straight-cylindrical shank.

Ensure the spindle and workpiece are properly secured before operation, and confirm chuck or collet runout is within acceptable limits to avoid bit breakage at this diameter. Coolant through is not supported on this bit; external coolant or cutting fluid application is recommended when drilling steel or stainless steel. Inspect the cutting edges before each use, as small-diameter HSS bits are susceptible to chipping if dropped or improperly stored.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.10 mm (0.0433 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 39.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00 mm\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 Point Angle\u003c\/strong\u003e: 140 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\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\u003eDiameter 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.012 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: 61511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733042331954,"sku":"61511","price":32.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80805d3e6b6a0fd84a195ddc2dc070af.jpg?v=1788750895","url":"https:\/\/voomisupply.com\/products\/osg-61511-screw-machine-drill-bit-0-0433-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
