It carries a wire gauge size of 45, which corresponds to a decimal diameter of 0.082 inches, and a straight-cylindrical shank of the same diameter for secure chuck seating. The 135-degree split point is self-centering and web-thinned, reducing the thrust needed to start a hole without a center punch. The straw finish indicates a heat-treatment process consistent with cobalt tooling. Overall length is 6 inches with a 1.125-inch flute length, making this an extension-length drill suited for reaching into deeper clearances than a jobber-length bit allows.\u003c\/p\u003e\u003cp\u003eThis drill bit fits applications in aerospace fabrication, sheet metal work, structural steel, and general industrial machining where extension reach is required. The 4xD flute-length-to-diameter ratio and right-hand spiral flute geometry promote chip evacuation in blind and through holes. It conforms to NAS 907 Type J standards, which governs aircraft-quality drill bits. Machinists, maintenance technicians, and aerospace mechanics are the primary installers of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for superior heat and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces required starting thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraw finish consistent with cobalt high-temperature heat treatment\u003c\/li\u003e\n\u003cli\u003eExtension length at 6 inches overall for deep-reach drilling applications\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J aircraft-quality standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an aircraft-quality extension drill bit in Series CO501-6, suitable for use in standard straight-shank drill chucks and compatible drilling equipment sized for a 0.082-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tooling is installed by machinists and maintenance technicians using standard drill presses, CNC machining centers, or hand-held pneumatic and electric drills with a compatible chuck. Secure the straight-cylindrical shank firmly in the chuck before operation to prevent slippage under torque. Use appropriate cutting fluid when drilling hard metals to extend tool life and control heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.082 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\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: 0.082 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CO501-6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693442728242,"sku":"5996104","price":19.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a3e48cb1baf3e332194f6fb8f7c2a57_a0bc8920-e1d0-4ba1-aa75-c2206d0fbd74.jpg?v=1788312449","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996104-cobalt-drill-bit-wire-45","provider":"Voomi Supply","version":"1.0","type":"link"}
