Built to Series 157 specifications, it features a standard 118-degree point angle, a bright\/uncoated finish, and a straight-cylindrical shank. The shortened screw machine length body increases rigidity compared to jobber-length bits, reducing deflection during close-tolerance drilling. At 0.076 inches in diameter (Wire Size 48), this bit is suited for small-diameter pilot holes, through-holes, and precision work in metalworking applications. The parallel web configuration and web-thinned point reduce cutting resistance and improve chip evacuation. Two spiral flutes in a regular helix provide efficient material removal.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in cast iron, non-ferrous metals, and steel. The screw machine length format is a common choice in production environments, machining centers, drill presses, and handheld applications requiring a stiffer, more controlled cut. Its general-purpose performance rating makes it a practical option for maintenance, fabrication, and toolroom use where small-diameter precision drilling is required. The right-hand cutting direction is standard for conventional rotating spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire Size 48 (0.0760 inches) with a tight diameter tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across cast iron, steel, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eScrew machine length body increases rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose drilling without specialized coatings\u003c\/li\u003e\n\u003cli\u003eISO standards compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose screw machine drill bit suitable for use in standard drill chucks, drill presses, CNC machining centers, and handheld power tools accepting straight-cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with small-diameter drill bit handling. Secure the shank fully in a compatible chuck before operation and verify spindle runout is within acceptable limits to avoid bit breakage at this diameter. Always wear appropriate eye protection and follow applicable shop safety standards when drilling metal. Do not apply excessive feed pressure on small-diameter bits, as deflection or breakage risk increases significantly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\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 -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 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: 0.0023 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: 48748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51729841160498,"sku":"48748","price":33.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f895037d2ea1f0c94fae275204e55159.jpg?v=1788709543","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48748-screw-machine-drill-bit-wire-48","provider":"Voomi Supply","version":"1.0","type":"link"}
