Built from high speed steel (HSS) with a bright\/uncoated finish, this bit measures 0.348 inches in diameter and delivers a 118-degree standard point angle suitable for general-purpose work in cast iron, non-ferrous metals, and steel. The shortened screw machine length reduces deflection and improves rigidity compared to jobber-length bits, making it a reliable choice for drill press and CNC turret work where precision and repeatability matter.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machine shops, production facilities, and trade applications requiring consistent hole quality in metallic workpieces. The right-hand spiral flute configuration promotes efficient chip evacuation during through-hole and blind-hole drilling. The straight cylindrical shank fits standard drill chucks without adapters. Typical users include machinists, tool room technicians, and maintenance mechanics working on ferrous and non-ferrous stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eScrew machine length body reduces deflection and improves accuracy in short-reach drilling applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for easier penetration and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for cast iron, non-ferrous metal, and steel workpieces\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with parallel web configuration promotes consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids or dry in general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0010 inches for close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit in the CHICAGO-LATROBE Series 157 line, rated for primary workpiece materials including cast iron, non-ferrous metal, and steel.

Secure the straight cylindrical shank firmly in the chuck before operation and verify chuck key removal prior to spindle engagement. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.348 inches (Letter Size S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\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: 0.0616 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: 48819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51734827434290,"sku":"48819","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1032c6387d40daaa8c86f7da495d84be.jpg?v=1788767188","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48819-screw-machine-drill-bit-0-348-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
