Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree split point and a regular spiral flute for efficient chip evacuation. The straight cylindrical shank measures 0.250 inches in diameter, and the overall length is 4 inches with a flute length of 2.75 inches. Left-hand cutting direction makes this bit particularly useful for removing broken fasteners and reverse-threaded applications. It is intended for use by machinists, maintenance technicians, and metalworking professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose drilling in steel and cast iron in both shop and field environments. The web-thinned, tapered web configuration reduces thrust required at the cutting tip, improving performance in ferrous metals. Typical applications include bolt extraction, production drilling, and maintenance repair operations where a left-hand spiral is required to back out damaged or seized fasteners without additional tooling. It is sold individually and is compatible with standard drill chucks and drill presses accepting a 0.250-inch straight shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-rotation drilling and broken bolt extraction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability in ferrous metal applications\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose use in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves bit entry\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to obscure wear and suitable for regrinding\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks accepting 0.250-inch shanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose use in standard drill chucks and drill presses that accept a 0.250-inch straight cylindrical shank.

Ensure the workpiece is securely clamped before drilling. When using for broken fastener removal, the drill press or driver must be set to reverse rotation to engage the left-hand flute correctly. Inspect the cutting edges before each use and replace or regrind when wear is visible to maintain safe cutting performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eFlute Length\u003c\/strong\u003e: 2.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01220169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711963988274,"sku":"01220169","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4598adff7d31f3d51edc26e56f2f57a.jpg?v=1788481982","url":"https:\/\/voomisupply.com\/products\/value-collection-01220169-left-hand-jobber-drill-bit-e","provider":"Voomi Supply","version":"1.0","type":"link"}
