Sized to wire gauge No. 42 with a decimal diameter of 0.0935 inches, the bit features a 135-degree split point for fast, self-centering starts without a center punch. A straw finish indicates the cobalt content and heat treatment level. The straight-cylindrical shank seats securely in standard drill chucks. This is a two-flute, right-hand cutting drill with a spiral flute design and tapered web configuration, built to Series CO501-6 standards and conforming to NAS 907 Type J.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for aerospace, sheet metal, and general precision-hole work where a wire-gauge No. 42 diameter is specified. The extended 6-inch overall length allows access to deep or recessed locations that standard-length bits cannot reach. The 1.25-inch flute length and 4xD flute-to-diameter ratio provide adequate chip evacuation in short-hole applications at this diameter. It is typically used by machinists, aviation maintenance technicians, and metalworkers drilling steel, stainless, titanium, and other hard alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for heat and wear resistance in hard metals and abrasive alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length for extended reach into deep or obstructed workpieces\u003c\/li\u003e\n  \u003cli\u003eStraw finish indicating cobalt-grade heat treatment\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with tapered web for consistent chip clearance\u003c\/li\u003e\n  \u003cli\u003eConforms to NAS 907 Type J standard for aircraft-quality drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit option for applications specifying a wire gauge No. 42 cobalt aircraft extension drill with a 0.0935-inch diameter and straight-cylindrical shank conforming to NAS 907 Type J.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and aviation maintenance technicians using standard drill chucks compatible with a 0.0935-inch straight-cylindrical shank. Secure the workpiece firmly before drilling and use appropriate cutting fluid or lubricant when working with hard alloys to extend tool life. Do not exceed the recommended feed rate or spindle speed for the material being drilled. Inspect the split point for chipping or wear before each use and replace the bit if the cutting edges are degraded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0935 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: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0935 inches\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: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFlute Length X Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5996092\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51705998573874,"sku":"5996092","price":15.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a3e48cb1baf3e332194f6fb8f7c2a57_4e52c99c-da8a-4a0d-ad0d-5c6a428bac8d.jpg?v=1788432171","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996092-cobalt-drill-no-42-6in","provider":"Voomi Supply","version":"1.0","type":"link"}
