It carries a wire gauge size of 56, which corresponds to a decimal diameter of 0.0465 inches. The bit is manufactured from high speed steel with a coating applied to extend cutting life. A 135-degree split point reduces walking at entry and lowers the thrust needed to start the hole. The shortened screw machine length body provides added rigidity compared to jobber-length bits, making it well suited for close-tolerance work on drill presses, CNC machines, and turret lathes. This is a production-grade, heavy-duty bit built to NAS 907 and ISO standards.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in metal fabrication, machining, and production drilling applications where hole accuracy and tool life matter. The screw machine length format is common in shop environments where shorter stickout improves rigidity and reduces deflection in small-diameter holes. It is appropriate for both manual and CNC setups drilling cast iron and steel workpieces. The 2-flute regular spiral design handles chip evacuation efficiently in these materials. Machinists, tool-and-die workers, and maintenance technicians working in industrial and manufacturing settings are the primary users of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 56 diameter at 0.0465 inches for close-tolerance small-hole drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web construction for improved chip clearance and lower cutting force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body adds rigidity over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ISO standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a production-grade screw machine length drill bit for use in cast iron and steel drilling applications.

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation and verify runout is within acceptable limits for the diameter. Apply appropriate cutting fluid or lubricant when drilling steel to reduce heat buildup and extend tool life. Never exceed the recommended RPM range for this diameter in the material being drilled.\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 Size (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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\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\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\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: Split\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 48426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51739186692402,"sku":"48426","price":71.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c444fe9af03d3c45580d01d2b65397ec.jpg?v=1788811033","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48426-screw-machine-drill-bit-0-0465-in","provider":"Voomi Supply","version":"1.0","type":"link"}
