Left-hand drill bits are commonly used by machinists and technicians to extract broken fasteners, studs, and bolts — in many cases, the reverse cutting action backs the damaged fastener out without requiring additional extraction tools. The jobber-length geometry provides a practical balance of reach and rigidity for general-purpose drilling in a wide range of materials including steel, aluminum, and other common metals.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in machine shops, maintenance and repair environments, and field service applications where broken or seized fasteners are encountered. It is sized at 5\/16 inch, making it appropriate for extracting fasteners in the 5\/16-inch and closely related size ranges. Machinists, millwrights, and mechanical technicians are the primary users of left-hand drill bits in production and repair settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-rotation drilling and fastener extraction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of metal materials\u003c\/li\u003e\n\u003cli\u003eJobber-length design balances reach and rigidity for general-purpose use\u003c\/li\u003e\n\u003cli\u003e5\/16-inch diameter for common fastener extraction and drilling tasks\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use left-hand HSS jobber drill bit compatible with conventional drill chucks and reversible drill presses or hand drills accepting 5\/16-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLeft-hand drill bits must be used in a reversible drill or drill press set to counterclockwise rotation. Secure the workpiece firmly before drilling to prevent movement. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain cutting edge integrity. Always wear appropriate eye protection when operating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Left-hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Style\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LHJ100-020-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233306116402,"sku":"LHJ100-020-I","price":15.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623353.png?v=1780096894","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-lhj100-020-i-left-hand-hss-jobber-drill-5-16","provider":"Voomi Supply","version":"1.0","type":"link"}
