Built from high-speed steel (HSS) with a bright uncoated finish, it measures 23\/64 inches (0.3594 inches) in diameter and carries a 118-degree point angle. The overall length is 3-1\/16 inches, making it suited for work in tight clearance situations where standard-length bits are too long. The web-thinned geometry reduces entry resistance and helps maintain point alignment. This bit is installed and used by machinists, maintenance technicians, and trade professionals who require left-hand rotation for extractor-assisted screw removal or reverse-spindle setups.\u003c\/p\u003e\n\u003cp\u003eThe 48923 fits applications involving aluminum, copper, magnesium, slate, thermoplastic, and wood. Its screw machine length profile is common in production drilling environments and repair work where short, rigid bit engagement matters. The straight shank accommodates standard drill chucks, and the regular spiral flute geometry supports consistent chip evacuation across the listed workpiece materials. This bit belongs to the Series 157L lineup and conforms to ISO standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction for use with reverse-rotation setups and screw extraction workflows\u003c\/li\u003e\n  \u003cli\u003e23\/64 inches (0.3594 inches) diameter with a tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, parallel web configuration for reduced thrust\u003c\/li\u003e\n  \u003cli\u003eHSS construction with bright uncoated finish suitable for non-ferrous metals, plastics, and wood\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (3-1\/16 inches OAL) provides rigidity in confined drilling spaces\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral geometry promotes efficient chip clearing across supported materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks in drill presses, lathes, or hand drills configured for left-hand or reverse rotation.

Secure the workpiece firmly before drilling to prevent movement during engagement. Use appropriate cutting fluid or lubrication for metal workpieces to extend bit life. Inspect the cutting edges and web before each use; a damaged point will affect hole accuracy and diameter tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 23\/64 inches (0.3594 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches (9.13 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-5\/16 inches (1.3125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left 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\u003eTool Material\u003c\/strong\u003e: HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Copper, Magnesium, Slate, Thermoplastic, Wood\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.0685 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: 48923\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728484237618,"sku":"48923","price":28.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26bf95d1af3519169c0cccb85a7c8169.jpg?v=1788691933","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48923-screw-machine-drill-bit-23-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
