Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit handles demanding applications where standard HSS tooling fails prematurely. It carries a No. 50 wire gauge size, translating to 0.0700 inches in decimal, with a 135-degree split point that self-centers on contact and reduces thrust force. Overall length is 2 inches with a 1-inch flute length and a straight-cylindrical shank. The two-flute spiral design promotes efficient chip evacuation in deep holes. Licensed HVAC, plumbing, and mechanical contractors reach for bits like this when drilling stainless, titanium, or other high-strength alloys during equipment installation and fabrication work.\u003c\/p\u003e\n\u003cp\u003eThe 46720 is designed for precision drilling in titanium, stainless steel, and similarly hard workpiece materials. The web-thinned, tapered web construction reduces cutting resistance at the tip, making it well-suited for close-tolerance hole work where bit walk and oversizing cannot be tolerated. It conforms to DIN 338 and NAS 907 Type J standards, making it appropriate for aerospace-grade and industrial maintenance applications. Sold individually per package, with a minimum order quantity of 12 units, this bit fits within standard drill index sets using No. 50 wire gauge positions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers on the workpiece and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides lubricity and heat resistance during high-speed drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and NAS 907 Type J standards for dimensional and performance consistency\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with right-hand cut suits standard drill press and hand-drill operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock drill bit fitting standard No. 50 wire gauge positions in jobber length drill indexes.

Secure the workpiece before drilling to prevent movement, and use appropriate cutting fluid or lubricant when drilling hard alloys to manage heat buildup. Do not exceed recommended RPM ranges for the material and bit diameter. Inspect the bit for wear or chipping before each use, as a compromised cutting edge increases the risk of bit breakage in hard materials.\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. 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0024 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: 46720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51739076264242,"sku":"46720","price":43.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_27e87167-930f-4baa-a1cb-883463cb4ad0.jpg?v=1788808983","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46720-cobalt-jobber-drill-bit-no-50","provider":"Voomi Supply","version":"1.0","type":"link"}
