Built from high speed steel (HSS) with a bright\/uncoated finish, this bit runs at a 0.242 inch diameter and features a 118-degree standard point angle for general purpose cutting. The stub-length body measures 2.5 inches overall, keeping the tool rigid and reducing deflection in short-reach applications. Web thinning reduces thrust load at the cutting tip, making it well suited for hand-fed and machine-fed setups on cast iron, non-ferrous metal, and steel workpieces.\u003c\/p\u003e\u003cp\u003eThe 48803 fits standard drill chucks via its straight cylindrical shank and is used in screw machine operations, manual drill presses, and CNC turret setups where a compact cutting length is required. Its 1.375 inch spiral flute length provides adequate chip evacuation on shallow-to-moderate depth holes. This bit targets machinists, tool and die workers, and maintenance technicians working with cast iron, steel, and non-ferrous materials in shop and field environments. The diameter tolerance of plus 0.0000 to minus 0.0007 inches ensures close-tolerance hole sizing without reaming in many general purpose applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.242 inch (Letter size C) diameter with tight tolerance: plus 0.0000 to minus 0.0007 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced thrust and easier penetration\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability on cast iron, steel, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.5 inches overall keeps the tool rigid and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluid in general purpose machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct stock drill bit for standard drill chucks and screw machine tooling setups.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid when drilling steel or cast iron to extend tool life and maintain dimensional accuracy. Inspect the cutting edges before use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0000 to minus 0.0007 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: 0.0253 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: 48803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738348257586,"sku":"48803","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47403e6a745ccf8ad74a748bee00ee5a.jpg?v=1788798506","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48803-screw-machine-drill-bit-0-242-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
