Built from high-speed steel (HSS) with a bright uncoated finish, this bit features a 19\/64-inch (0.2969 inch) diameter, a standard 118-degree drill point angle, and a regular spiral flute configuration. The screw machine length format provides a shorter, more rigid profile compared to jobber-length bits, reducing deflection and improving hole accuracy in production and repair environments. Web-thinned construction reduces cutting resistance at the tip. Machinists, tool and die technicians, and maintenance trades install this bit in drill presses, lathes, and hand-held drilling equipment.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling aluminum, copper, magnesium, slate, thermoplastic, and wood. The left-hand cutting direction makes it particularly useful for extracting broken right-hand screws and fasteners, as the reverse cutting action can back out a damaged fastener while drilling. Its straight shank and compact overall length of 2-3\/4 inches make it compatible with standard drill chucks in both benchtop and portable equipment. This is a single-piece package intended for individual replacement or stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cut direction aids broken fastener removal during reverse drilling\u003c\/li\u003e\n  \u003cli\u003eHSS construction provides durability across a range of non-ferrous and soft materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard drill point angle for general-purpose entry performance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tip reduces thrust force and improves penetration efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2-3\/4 inches OAL) delivers increased rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains sharp edges and allows easy visual inspection for wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 48919 belongs to CHICAGO-LATROBE Series 157L and is rated for use in aluminum, copper, magnesium, slate, thermoplastic, and wood.

Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. When using a left-hand bit for fastener extraction, confirm the drilling equipment is set to reverse rotation before engaging the bit. Inspect the cutting edges before each use and replace bits that show chipping or heat discoloration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches (1.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2969 inches (7.54 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-3\/16 inches (1.1875 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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Copper, Magnesium, Slate, Thermoplastic, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 157L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 48919\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51746415149362,"sku":"48919","price":21.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/925257afabd50c20cdce99f772265f5d.jpg?v=1788869817","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48919-19-64-in-hss-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
