It measures 5.00 mm in diameter with an overall length of 80.00 mm and features a 140-degree R-thinned point geometry that reduces thrust and improves centering on entry. The three-flute, regular spiral configuration increases chip evacuation speed compared to standard two-flute designs, making it well suited for short-cycle drilling operations. OSG's proprietary EgiAs multi-layer coating provides enhanced lubricity and wear resistance for extended tool life in ferrous and non-ferrous materials. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting edge, supporting higher feed rates and consistent hole quality.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in CNC machining centers, drill presses, and automated production equipment where screw machine length tooling is specified for rigidity and minimal deflection. The 6.00 mm straight cylindrical shank allows direct mounting in standard tool holders, collets, and hydraulic chucks. It is applicable across industries including aerospace, automotive, medical device manufacturing, and general metalworking wherever tight-tolerance, high-speed drilling is required. Licensed machinists and CNC operators are the primary installers and users of this tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eEgiAs multi-layer proprietary coating for improved wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eThree-flute design improves chip evacuation and enables higher feed rates\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point reduces entry thrust and improves hole position accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3xD flute ratio) provides maximum rigidity with minimal overhang\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eOSG Series 6600 tooling in the 5.00 mm to 6.50 mm diameter range. The 6.00 mm straight cylindrical shank is compatible with standard collet chucks, hydraulic chucks, and Weldon-style holders sized for that shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Verify that the tool holder bore matches the 6.00 mm shank diameter and that the bit is seated to the correct insertion depth per the holder manufacturer's specification. Confirm coolant-through passages are clear and coolant pressure is set within the machine's rated range before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80.00 mm (3.1496 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: Regular Spiral\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs Multi-Layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 8720500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736037228850,"sku":"8720500","price":200.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12e696daf0838dd409e193fde4e80837.jpg?v=1788775536","url":"https:\/\/voomisupply.com\/products\/osg-8720500-screw-machine-drill-bit-5mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
