Built to Series 5700 specs, it features a 180-degree flat bottom point geometry that produces clean, flat-bottomed holes without the tapered lead typical of standard drill points. The EgiAs multi-layer proprietary coating reduces friction and extends tool life in abrasive or hardened materials. With a 7.30 mm cutting diameter and a compact 75 mm overall length, this bit is well-suited for CNC machining centers, drill presses, and screw machine operations where rigidity and accuracy are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in metal fabrication, precision machining, and production drilling environments. The stub length body provides increased rigidity compared to jobber-length bits, making it effective in applications where deflection must be minimized and hole location accuracy is tight. It is installed and used by machinists, tool and die makers, and CNC operators working with ferrous and non-ferrous metals, alloys, and similar materials. The right-hand spiral flute design efficiently evacuates chips during through and blind-hole drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180-degree flat bottom point eliminates the center cone, producing flat-bottomed blind holes\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides superior hardness and wear resistance compared to high-speed steel\u003c\/li\u003e\n\u003cli\u003eEgiAs multi-layer coating reduces heat buildup and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length body increases rigidity and reduces deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation in production drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet systems without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for screw machine and CNC drilling applications requiring a 7.30 mm flat bottom carbide drill bit in the OSG Series 5700 range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by qualified machinists and CNC technicians. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the straight shank firmly in a properly sized collet or drill chuck to the tool holder manufacturer's specified clamping method. Do not use coolant-through setups with this bit, as the coolant-through feature is not supported on this model.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.30 mm (0.2874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 180 degrees (flat bottom)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm (2.95 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs Multi-layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.25 inches L x 0.65 inches W x 0.60 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 3330730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731603095858,"sku":"3330730","price":183.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6610b5b7e64749449347a1ca53a6449c_30f3e1bf-2e82-4fff-9efd-72b2defc545e.jpg?v=1788733066","url":"https:\/\/voomisupply.com\/products\/osg-3330730-screw-machine-drill-bit-7-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
