Built from high speed steel with a bright, uncoated finish, it measures 0.0625 inches (1\/16 inch) in diameter with an overall length of 1.625 inches and a flute length of 0.625 inches. The 118-degree standard point angle and web-thinned, parallel web construction promote clean entry and reduce thrust on entry. The straight-cylindrical shank seats securely in standard chucks. Licensed trade professionals and machinists rely on this Series 157L bit for precision work where a left-hand cutting direction is required.\u003c\/p\u003e\u003cp\u003eThis bit is suited for light-duty drilling in metals and non-metals including aluminum, copper, magnesium, slate, thermoplastic, and wood. The screw machine length format — shorter than jobber length — provides added rigidity and improved accuracy in drill press, turret lathe, and screw machine setups where minimal deflection matters. The two-spiral flutes evacuate chips efficiently even at small diameters, reducing the risk of bit walk or breakage in close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for use in left-hand rotation spindles or stud extraction applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length body improves rigidity and reduces deflection compared to jobber-length bits\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, parallel web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose use without added coating cost\u003c\/li\u003e\n\u003cli\u003eISO standard compliance for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks used in drill presses, turret lathes, screw machines, and CNC equipment accepting a 0.0625-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed by a machinist or qualified trade professional familiar with small-diameter tooling. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck runout is within tolerance, as small-diameter bits are sensitive to misalignment. Power down and lock out the spindle before changing bits. Avoid excessive feed pressure on small-diameter high speed steel bits, as they are prone to breakage under side load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 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\u003eFlute Type\u003c\/strong\u003e: Spiral, 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-Cylindrical\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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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 -0.0005 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: 0.0017 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727919153458,"sku":"48904","price":74.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec3eacaaed5a8475978be726bdaf0ce1.jpg?v=1788684524","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48904-screw-machine-drill-bit-0-0625-in","provider":"Voomi Supply","version":"1.0","type":"link"}
