Built from high speed steel with a coated finish, it measures 5.80mm (0.2283 inches) in diameter with a 120-degree faceted drill point and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard chucks and drill presses. At 72.00mm (approximately 2.835 inches) in overall length, the stub-style body provides rigidity and resistance to deflection, making it well suited for production drilling and close-tolerance work in steel and aluminum. This bit is part of OSG Series 1100 and is rated for high-performance cutting applications.\u003c\/p\u003e\u003cp\u003eThe OSG 61558 is intended for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its shorter screw machine length body reduces overhang and improves hole location accuracy compared to jobber-length equivalents. Typical applications include production machining, CNC drilling, and manual drill press operations where rigidity and repeatability matter. A 5xD flute-to-diameter ratio provides adequate chip evacuation for most through-hole and shallow blind-hole applications in these materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.80mm (0.2283 inches) diameter with a tight tolerance of +0 to -0.018mm for close-fit hole applications\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point with web thinning for reduced entry force 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 (stub) length body at 72.00mm overall for maximum rigidity and minimal deflection\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design with straight-cylindrical 6.00mm shank for broad chuck compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with no coolant-through requirement, suitable for conventional flood or dry drilling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production-use drill bit for operations requiring a 5.80mm screw machine length stub drill in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. De-energize and lock out the machine before changing tooling. Follow applicable workplace safety standards and machine manufacturer guidelines for cutting fluid use, RPM selection, and feed rate when drilling the specified workpiece materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.80mm (0.2283 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72.00mm (approximately 2.835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00mm (approximately 1.102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 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, 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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 -0.018mm\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: 0.01 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: 61558\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734634332466,"sku":"61558","price":67.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16b864f95d667a88eb85f9b26f18a0fd.jpg?v=1788764166","url":"https:\/\/voomisupply.com\/products\/osg-61558-screw-machine-drill-bit-0-2283in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
