Built from high speed steel (HSS) with an oxide finish, it delivers reliable performance in general-purpose production and maintenance drilling. The bit features a 118-degree standard point angle, a web-thinned and tapered web configuration for reduced thrust at entry, and a regular spiral flute for efficient chip evacuation. Overall length is 6 inches with a flute length of 3-5\/8 inches. It is part of the Series 120 line and is sized at 0.1990 inches diameter, corresponding to wire gauge size number 8.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shop, maintenance, and fabrication environments where drilling into ferrous metals is routine. The taper length body provides additional reach compared to a jobber-length bit, making it useful in applications where standard-length bits cannot access the work. Right-hand cut and straight shank make it compatible with conventional drill presses, lathes, and hand drills with standard chucks. It is sold individually and is appropriate for licensed machinists, maintenance mechanics, pipefitters, and general trade professionals working with metal substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish for basic surface protection and lubricity\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry into steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces drilling thrust and improves bit starting accuracy\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with right-hand cut for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, carbon steel, and cast iron applications.

Secure the workpiece firmly before drilling and ensure the bit is fully seated and tightened in the chuck before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and maintain hole tolerance. Always wear appropriate eye and hand protection per applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1990 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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: 50298\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733181202738,"sku":"50298","price":22.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa3644c0f51553ac8696c9baaa669d59.jpg?v=1788752410","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50298-taper-length-drill-bit-0-1990-in","provider":"Voomi Supply","version":"1.0","type":"link"}
