Built from high speed steel with a coated finish, this 27\/32 inch (0.8438 inch decimal) bit features a 118-degree point angle, two spiral flutes, and a straight-cylindrical shank. The shorter screw machine length body improves rigidity and reduces deflection compared to jobber-length bits, making it a reliable choice for close-tolerance work on drill presses and CNC equipment. A web-thinned tip reduces thrust requirements when starting holes and helps maintain accuracy in moderate to high production runs.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general purpose drilling in cast iron, non-ferrous metals, and steel. The Series 157 designation places it in a well-established line of screw machine bits used in production shops, maintenance facilities, and job shops. Its parallel web configuration and regular spiral type handle a broad range of ferrous and non-ferrous workpiece materials without specialized tooling or setup. Licensed machinists and industrial maintenance technicians are the typical end users, though experienced fabricators also reach for this size in structural and mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/32 inch diameter with a decimal size of 0.8438 inches and a tight tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for reduced thrust on entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and reduces deflection during drilling\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with parallel web configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard drill chucks and holders\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 for use in cast iron, non-ferrous metal, and steel workpieces.

Secure the straight shank firmly in the chuck or collet to the full depth of the shank engagement to prevent slipping under load. Machining professionals should confirm appropriate spindle speed and feed rate for the workpiece material and bit diameter before cutting. Cutting fluid or coolant is recommended for steel applications to extend tool life, even though this bit does not feature a coolant-through design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 27\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.8438 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\u003eOverall Length\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.5 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 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 -0.0012 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: 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: 0.61 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: 48554\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":52061432217906,"sku":"48554","price":81.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f42ab0bf2a7caee0f4ed7402de519b91.jpg?v=1790041808","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48554-screw-machine-drill-bit-27-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
