Sized to wire gauge No. 46 (0.081 inches decimal), it features a 135-degree split point for self-centering starts without a center punch and a straw finish that indicates cobalt content and provides light oxidation resistance. The 6-inch overall length gives technicians extended reach in confined airframe, structural, or industrial applications. Right-hand spiral flutes with a 4xD flute-length-to-diameter ratio evacuate chips efficiently during deep-hole passes. Licensed machinists, aircraft mechanics, and metalworking tradespeople are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for aircraft maintenance and precision metalworking environments where tight tolerances and hole quality are critical. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. At 1.125 inches of flute length, it handles moderate-depth holes while the extended body provides clearance past obstructions common in panel and structural drilling. The CO501-6 series is a general-purpose cobalt line suited to production and maintenance drilling in ferrous and non-ferrous hard materials. It meets NAS 907 Type J standards, making it appropriate for aerospace-regulated work.\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-metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry eliminates center-punch step\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and entry force\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach in tight or obstructed work areas\u003c\/li\u003e\n  \u003cli\u003eStraw finish indicates cobalt grade and provides light surface protection\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type J compliant for aerospace maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any standard drill chuck or collet accepting a 0.081-inch straight-cylindrical shank.

Set drill speed according to material hardness and bit diameter guidelines — smaller diameter cobalt bits require higher RPM and lighter feed pressure to avoid breakage. Inspect the split point for chipping before each use; a damaged point will wander and compromise hole tolerance. Follow applicable shop safety and aviation maintenance manual procedures when drilling structural components.\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. 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.081 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\u003eDrill Point Angle\u003c\/strong\u003e: 135 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: Straw\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: 0.081 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003eStandards\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 5996107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694565196082,"sku":"5996107","price":19.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a3e48cb1baf3e332194f6fb8f7c2a57_4fd8f0d0-9529-4a7d-a74e-44f608414ff7.jpg?v=1788325564","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996107-cobalt-aircraft-drill-no-46","provider":"Voomi Supply","version":"1.0","type":"link"}
