Manufactured from high speed steel with a bright\/uncoated finish, this bit measures 0.377 inches in diameter and corresponds to Letter V sizing. The 118-degree standard point angle is ground to a web-thinned, parallel web configuration, reducing thrust and improving centering on entry. Overall length is 3.25 inches with a 1.875-inch flute length, making it well suited for use in turret lathes, screw machines, and short-reach drilling applications where rigidity matters. The straight-cylindrical shank seats securely in standard drill chucks.\u003c\/p\u003e\u003cp\u003eThis bit is rated for cutting cast iron, non-ferrous metals, and steel under general-purpose conditions. The regular spiral, two-flute design promotes efficient chip evacuation during moderate-feed drilling. It is a practical choice for machine shops, HVAC fabricators, pipefitters, and electricians drilling pilot or clearance holes through structural steel, aluminum, and similar workpiece materials. The Series 157 designation indicates CHICAGO-LATROBE standard screw machine geometry with ISO-conforming dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter V size — 0.377-inch diameter with a tolerance of +0.0000 to -0.0010 inches for accurate hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning for reduced entry thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction — suitable for cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — compatible with cutting fluid application and easy to regrind\u003c\/li\u003e\n\u003cli\u003eScrew machine length at 3.25 inches overall for maximum rigidity in chucked setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral, two-flute design for effective chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit suitable for use in standard drill chucks, turret lathes, and CNC screw machine setups that accept straight-cylindrical shanks in the 0.3500 to 0.4000-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, tool-and-die technicians, or qualified tradespeople using a keyed or keyless drill chuck rated for the shank diameter. Ensure the machine spindle is fully stopped and locked before changing bits. Secure the shank fully in the chuck to prevent slippage under load. Apply cutting fluid or coolant appropriate to the workpiece material to extend tool life and maintain hole-size tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.377 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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\u003eSeries\u003c\/strong\u003e: 157\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: 0.0761 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51734873014578,"sku":"48822","price":16.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9293735ca371e740596a5037e163fd33.jpg?v=1788767490","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48822-screw-machine-drill-bit-0-377-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
