The bit measures 9.00 mm (0.3543 inches) in diameter with a 120-degree faceted point angle and a web-thinned, tapered web configuration that reduces thrust and improves centering. Built from high speed steel (HSS) with a coated finish, this bit is engineered for right-hand cut operation with a regular spiral flute profile. The straight-cylindrical shank measures 10.00 mm and fits standard drill chucks. It is installed by machinists, tool and die workers, and maintenance technicians working in light manufacturing, metalworking shops, and industrial maintenance settings.\u003c\/p\u003e\u003cp\u003eThis screw machine length drill bit is suited for drilling into steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. The shorter screw machine length body offers increased rigidity compared to jobber-length bits, making it a reliable choice for close-tolerance hole production on drill presses, CNC machining centers, and manual lathes. The flute-to-diameter ratio is 5xD, and the two-flute spiral design promotes chip evacuation during through-hole and blind-hole operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9.00 mm (0.3543 inch) cutting diameter with a tolerance of +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e120-degree faceted point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (10.00 mm) for positive chuck engagement\u003c\/li\u003e\n\u003cli\u003eScrew machine length body for added rigidity in production drilling\u003c\/li\u003e\n\u003cli\u003eCoolant-through: No — suited for conventional flood or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 10.00 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet bore matches the 10.00 mm shank diameter before tightening. Apply appropriate cutting fluid or dry-cut per the workpiece material requirements and shop practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.00 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90.00 mm (3.543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40.00 mm (1.575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\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\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.094 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: 61590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730042421554,"sku":"61590","price":82.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12863e067ddb650bb484a476c211fe9c.jpg?v=1788710648","url":"https:\/\/voomisupply.com\/products\/osg-61590-screw-machine-drill-bit-0-3543-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
