Built from high speed steel with a coated finish, it carries a 135-degree split point that reduces walking and lowers thrust on entry. The stub-length body keeps deflection low in short-reach applications. With a wire gauge diameter of #56 (0.0465 inches) and a diameter tolerance of +0.0000 to -0.0005 inches, the bit holds tight size control for precision hole work. Right-hand spiral flutes evacuate chips efficiently. Licensed trades and machining professionals install this bit in screw machine setups, drill presses, and handheld power tools.\u003c\/p\u003e\n\u003cp\u003eThe 49426 is suited for drilling operations in residential and commercial trade environments where short, rigid tooling is preferred over jobber-length bits. Its 1-3\/8 inch overall length and 1\/2 inch flute length make it well matched to close-clearance fixtures and screw machine turrets. Primary workpiece materials are cast iron and steel, making it a practical choice for HVAC, plumbing, and mechanical contractors drilling structural steel, pipe hangers, and equipment enclosures. The parallel web configuration and web-thinned geometry support consistent entry geometry across repeated drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers required thrust on entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body minimizes deflection in short-reach and fixture-guided applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web geometry supports clean, consistent hole entry\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for tight size control\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ISO standards; Series 159 heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-production drill bit for screw machine setups and power drill applications targeting cast iron and steel workpieces in the 0.0000 to 0.1000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, tool-and-die technicians, and trade professionals using screw machines, drill presses, or handheld power tools. Secure the straight-cylindrical shank fully in the chuck before operation to prevent slippage. Match spindle speed to the workpiece material and bit diameter per standard feeds-and-speeds references for high speed steel tooling. Inspect the cutting edges and web for wear or chipping before each use; a damaged split point affects hole size and finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\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\u003eOverall Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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: 159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0011 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: 49426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51746892939570,"sku":"49426","price":33.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f64f4ecd9dddb718f7be4cca73e1e54c.jpg?v=1788874396","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49426-screw-machine-drill-bit-0-0465-in","provider":"Voomi Supply","version":"1.0","type":"link"}
