At 0.5 inches (1\/2 inch) in diameter, it carries a 120-degree drill point angle with an X-Thinned web for reduced entry force and cleaner starts. The WXL coating improves wear resistance and heat dissipation during extended cuts. With a flute-to-diameter ratio of 20xD and a 292 mm flute length, this bit is built for applications where standard-length drills cannot reach. Machinists, tool and die makers, and industrial maintenance technicians working with hard alloys or stainless steel are the primary users.\u003c\/p\u003e\u003cp\u003eThis extra-length drill bit is suited for deep-hole work in ferrous and non-ferrous metals, including alloy steels, stainless steel, cast iron, and hard plastics. Its spiral right-hand cutting flutes with a regular spiral type provide efficient chip evacuation in production and maintenance machining environments. The straight-cylindrical shank fits standard drill chucks without adapters. Coolant-through capability is not available on this model, so external flood coolant or cutting oil is recommended when drilling deep holes in heat-sensitive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for high-heat resistance and durability in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003eWXL coating for extended tool life and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle with X-Thinned web for fast, accurate entry\u003c\/li\u003e\n\u003cli\u003e20xD flute-to-diameter ratio enables deep-hole drilling beyond standard reach\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes with right-hand cutting direction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/2 inch shank fits standard chucks without reduction sleeves\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use extra-length drill bit for industrial drill chucks and CNC machining centers accepting a 1\/2 inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or industrial maintenance technicians familiar with drill press, lathe, or CNC operations. Secure the shank fully in the chuck jaws before operation and verify runout before cutting. Power down and de-energize the machine spindle before changing or inspecting the bit. Apply external flood coolant or cutting oil when drilling deep holes, as this bit does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 360 mm (approximately 14.17 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 292 mm (approximately 11.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: WXL\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 20xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 17524911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751934722354,"sku":"17524911","price":777.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c299f4040d85119fce02e3f3e36ad38_73c6dc6e-7078-43aa-923e-633c24a60a52.jpg?v=1788924770","url":"https:\/\/voomisupply.com\/products\/osg-17524911-extra-length-cobalt-drill-bit-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
