It features a 6.50 mm diameter with a flat-bottom, 180-degree point geometry designed to produce flat-bottomed holes without the need for a spotting drill. The EgiAs multi-layer coating provides enhanced wear resistance and heat management at the cutting edge. At 70.00 mm overall length (2.7559 inches) with a 30.00 mm flute length, this short-length drill offers increased rigidity and reduced deflection compared to jobber-length alternatives. It is installed and operated by machinists and tool-and-die professionals working on CNC or manual drilling equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in steel, cast iron, and hardened materials where a flat-bottom hole or close-tolerance bore is required. The screw machine length format is common in turret lathes, CNC machining centers, and drill presses where short tool overhang improves accuracy and tool life. The 3xD flute-to-diameter ratio and tapered web configuration support efficient chip evacuation in these materials. Coolant-through capability makes it compatible with through-spindle coolant setups for deep or high-speed applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180-degree flat-bottom point geometry eliminates the need for pre-spotting in many setups\u003c\/li\u003e\n\u003cli\u003eEgiAs multi-layer proprietary coating for extended tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and heat resistance beyond high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports through-spindle coolant delivery for improved chip flushing\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and improves cutting efficiency\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for standard CNC and manual machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in machining applications targeting steel, cast iron, and hardened materials; fits standard straight-shank tool holders accepting an 8.00 mm (0.3150 inch) shank diameter.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the bit. When using coolant-through capability, verify that spindle coolant pressure and flow rate are within the machine tool manufacturer specifications. Follow applicable shop safety standards and machine guarding requirements during setup and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.50 mm (0.2559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm (2.7559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat Bottom\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5720\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.1 inches L x 0.65 inches H x 0.6 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3334348\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732571586866,"sku":"3334348","price":178.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1009c2e4540f28444916b42e80c3ac5_64b232b4-e5bc-4482-8b55-4d0234d3352e.jpg?v=1788744554","url":"https:\/\/voomisupply.com\/products\/osg-3334348-screw-machine-drill-bit-6-50mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
