Built to Series CO501-6 standards and conforming to NAS 907 Type J, this bit features a 135-degree split point that is self-centering, reducing the need for a center punch and minimizing walking on entry. The wire size No. 49 cutting diameter measures 0.073 inches. The straw finish indicates a heat-treated cobalt steel construction suited for tougher materials. With a 1-inch flute length and 6-inch overall length, it is sized for extended-reach work in confined or deep locations. Licensed HVAC techs, machinists, and aviation maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for general-purpose extended-reach drilling in hard metals, stainless steel, titanium, and high-temperature alloys. The extra overall length of 6 inches makes it suitable for applications where standard-length bits cannot reach the work surface. It is appropriate for both production shop environments and field service maintenance situations where precision hole sizing to wire gauge No. 49 is required. The right-hand spiral flute with web-thinned, tapered web configuration promotes efficient chip evacuation during drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool steel construction for drilling hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering and reduces walking on entry\u003c\/li\u003e\n\u003cli\u003eStraw finish indicates heat treatment for improved hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e6-inch overall length provides extended reach for confined or deep access drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 907 Type J standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style extended-reach drill bit for use in standard drill chucks accepting a 0.073-inch straight cylindrical shank, compatible with hand drills, drill presses, and pneumatic drilling equipment used in aerospace and industrial maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by machinists, aviation maintenance technicians, and industrial tradespeople familiar with metal drilling procedures. Secure the workpiece firmly before drilling and use appropriate cutting fluid or lubricant when working with hard metals to extend tool life and maintain hole accuracy. Always verify spindle speed is appropriate for the material and bit diameter before operation. Inspect the bit for wear or chipping before each use and replace if the cutting edges are degraded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 49\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.073 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.073 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 4xD\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CO501-6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: 5996116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707911668018,"sku":"5996116","price":19.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a3e48cb1baf3e332194f6fb8f7c2a57_20362c27-6a35-44d3-8788-333986e23cf6.jpg?v=1788442849","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996116-cobalt-drill-bit-no-49","provider":"Voomi Supply","version":"1.0","type":"link"}
