Built from high speed steel with a coated finish, this bit measures 0.689 inches (17.50 mm) in diameter and features a 120-degree faceted drill point for accurate entry and reduced walking. The shortened screw machine length format provides increased rigidity compared to jobber-length bits, making it well suited for use in drill presses, CNC machining centers, and turret lathes where controlled depth and minimal deflection are priorities. Two spiral flutes with a web-thinned, tapered web configuration improve chip evacuation and reduce thrust during cutting.\u003c\/p\u003e\u003cp\u003eThis bit is engineered for production drilling in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank with a 20.00 mm shank diameter seats securely in standard chucks and collets. The Series 1100 designation places this tool within OSG's high-performance drill line, intended for shops running moderate-to-high volume metal cutting operations where tool life and hole quality are critical. It is sold individually and is appropriate for both manual and CNC-controlled setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.689 inch (17.50 mm) cutting diameter with a tolerance of +0 to -0.027 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point reduces thrust and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length format increases rigidity and reduces deflection versus jobber-length drills\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral, 2-flute design handles a broad range of metal workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting a 20.00 mm straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in the chuck or collet to the manufacturer-recommended engagement depth before operation. Use appropriate cutting fluid or coolant for the workpiece material when drilling steel or stainless steel to manage heat buildup; note that this bit does not support coolant-through delivery. Inspect the cutting edges and web-thinned point for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.689 inches (17.50 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: 128.00 mm (approximately 5.04 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60.00 mm (approximately 2.36 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.027 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: 0.515 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: 61675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747646144818,"sku":"61675","price":316.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_e1cb3121-e6fc-47f3-9266-73bf1595ca9c.jpg?v=1788884031","url":"https:\/\/voomisupply.com\/products\/osg-61675-screw-machine-drill-bit-0-689-in-hss-120-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
