Built from high speed steel with a coated finish, this bit measures 0.7283 inches (18.50 mm) in diameter and features a 120-degree faceted point angle for accurate, self-centering entry. The regular spiral flute geometry with web thinning reduces thrust and improves chip evacuation, making it well suited for production drilling where cycle time and hole quality matter. A straight-cylindrical shank at 20.00 mm diameter seats securely in standard drill chucks and tool holders. Right-hand cut with a 5xD flute-to-diameter ratio rounds out the core specification.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. The screw machine length body keeps overhang short and rigidity high, which is a common requirement on CNC machining centers, turret lathes, and drill presses running close-tolerance production work. The tapered web configuration and high performance grade make it a practical choice for shops that need consistent hole quality across multiple materials without changing tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.7283 inch (18.50 mm) cutting diameter with a tolerance of +0 to -0.033 mm\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted point angle for self-centering entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel with coated finish for extended tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body maximizes rigidity and minimizes deflection in short-reach applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute, straight-cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the shank fully in a properly sized chuck or collet before operation and confirm tool runout is within acceptable limits. Always power down and lock out the machine spindle before inserting or removing the bit. Follow shop-specific feeds-and-speeds guidelines for the workpiece material and do not exceed the drill press or machining center spindle speed rated for this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.7283 inches (18.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 130.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 64.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 20.00 mm\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.033 mm\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: 0.54 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: 61685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750927892786,"sku":"61685","price":347.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_b3a9559b-bb85-4e9e-bdf0-e2d149c10907.jpg?v=1788920663","url":"https:\/\/voomisupply.com\/products\/osg-61685-screw-machine-drill-bit-0-7283-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
