Built from high speed steel with a coated finish, this bit features a 135-degree split point with web thinning for fast penetration and reduced thrust on entry. The straight-cylindrical shank seats securely in standard drill chucks. At 0.0595 inches in diameter (Wire Size 53) and 1.625 inches overall length, it is engineered for close-tolerance work requiring a diameter tolerance of +0.0000 to -0.0005 inches. Two spiral flutes in a regular helix evacuate chips efficiently during continuous-feed operation.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron and steel in production machining, sheet metal fabrication, and precision assembly environments. The screw machine length (stub) configuration provides rigidity and reduced deflection compared to jobber-length bits, making it well-suited for drill press, CNC turret, and screw machine operations where short, stiff tooling is preferred. It meets NAS 907 specification requirements and is manufactured to ISO standards, supporting quality-controlled production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire Size 53 diameter at 0.0595 inches with tight tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and self-centers on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 specification and manufactured to ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Always bring the spindle to a full stop before changing tooling. Follow machine manufacturer guidelines and applicable shop safety standards when selecting feed rates and speeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0595 inches (Wire Size 53)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches\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\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO, NAS\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\u003eWeight\u003c\/strong\u003e: 0.0016 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 49423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730502615346,"sku":"49423","price":33.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fc3b6fae48330f114198df3fcf68a83.jpg?v=1788718606","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49423-screw-machine-drill-bit-0-0595-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
