Built to NAS 907 Type B standards, it features a 135-degree split point that reduces walking on entry and lowers thrust requirements compared to a conventional 118-degree point. The two-flute spiral design with a gold finish and tapered web construction suits high-performance drilling applications in hard and abrasive materials. This bit is installed by machinists, maintenance technicians, and trade professionals working with tight-tolerance bore requirements.\u003c\/p\u003e\n\u003cp\u003eThe 47783 is engineered for drilling titanium and similarly hard workpiece materials where standard HSS bits lose cutting edge integrity prematurely. Its straight-cylindrical shank measures 0.0730 inches in diameter, compatible with standard drill chucks. With a flute length of 1.0000 inch and a shank length of 1.0000 inch, it fits compact drilling setups where a short-length bit is not practical but a full jobber reach is still manageable. Series 550ASP designates Chicago-Latrobe's heavy-duty cobalt line built for demanding production and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for heat resistance and extended tool life in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces center walking and cutting thrust on entry\u003c\/li\u003e\n  \u003cli\u003eGold finish serves as a wear indicator and provides light lubricity\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains bit rigidity across the flute length\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant for applications requiring specification traceability\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.0730-inch straight-cylindrical shank.

Secure the shank fully in the chuck before operation and confirm runout is within tolerance to prevent premature bit breakage at this small diameter. Use appropriate cutting fluid or lubricant when drilling titanium or hardened materials to manage heat buildup. Replace the bit when the gold finish is worn through at the cutting edges, as this indicates the cobalt substrate is approaching its wear limit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0730 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\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold\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\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0000 inch\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: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47783\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51740619899186,"sku":"47783","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c60e882918ae7af67a6219dfbc0a36_a63bdd6b-200c-42be-af13-da4114c6f478.jpg?v=1788826254","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47783-cobalt-jobber-drill-bit-no-49","provider":"Voomi Supply","version":"1.0","type":"link"}
