Built from high speed steel with a coated finish, this bit measures 0.2244 inches (5.70 mm) in diameter with an overall length of 72.00 mm and a flute length of 28.00 mm. The 120-degree faceted point and web-thinned, tapered web configuration reduce entry force and improve centering accuracy. The straight-cylindrical shank measures 6.00 mm in diameter, making it compatible with standard drill chucks. This is a Series 1100 tool rated for high-performance applications and is installed by machinists, tool-and-die workers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThe OSG 61557 is suited for screw machine operations and general-purpose drilling in production and maintenance environments. Its 5xD flute-to-diameter ratio and regular spiral flute geometry support efficient chip evacuation at moderate to high feed rates. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The right-hand cut, two-flute spiral design is well matched to drilling on drill presses, CNC machining centers, and turret lathes where short, rigid tooling is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted drill point for accurate entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (short) body provides increased rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank seats securely in standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Fits standard drill chucks and collets accepting a 6.00 mm straight-cylindrical shank. Suitable for drill presses, CNC machining centers, and screw machines requiring a short-length drill in the 0.2000 to 0.2500 inch (5.00 to 6.50 mm) diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove drill bits only after the spindle has come to a complete stop and the machine is de-energized or locked out per applicable OSHA lockout\/tagout procedures. Secure the straight-cylindrical shank fully in the chuck or collet to prevent pullout under load. Coolant-through is not supported on this bit; apply external cutting fluid appropriate for the workpiece material when drilling stainless steel or aluminum alloys. Inspect the cutting edges and coating for wear before each use and replace the bit when diameter tolerance can no longer be held.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2244 inches (5.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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: 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, Regular\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\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 -0.018 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: 0.015 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 61557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737344737586,"sku":"61557","price":67.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d154c53dc308f635a56b56c7d17be1d9.jpg?v=1788787376","url":"https:\/\/voomisupply.com\/products\/osg-61557-screw-machine-drill-bit-0-2244in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
