Built from M42 cobalt high-speed steel, it carries a 135-degree split point that reduces walking and allows immediate cutting without a center punch. At 0.098 inches (Wire Size 40) in diameter, this bit is suited for precision hole-making in ferrous materials where heat buildup and tool wear are primary concerns. Licensed machinists, tool-and-die shops, and industrial maintenance techs rely on this Series 559 bit for demanding, repetitive drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling cast iron and steel in applications that demand tight tolerances. The stub-length body provides added rigidity compared to jobber-length bits, reducing deflection in short-reach setups such as turret lathes, screw machines, and drill presses. It is well-suited to production environments where consistent hole diameter and repeatability matter. The parallel web configuration and web-thinned point ease chip evacuation and reduce thrust requirements in deep or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction resists heat and abrasion when drilling hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates the need for center-punching\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web design improves chip flow and lowers cutting force\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides rigidity and reduced deflection in close-quarters setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports tight-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eISO standard compliant for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks on drill presses, turret lathes, CNC machining centers, and screw machines.

Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation and verify chuck runout before production use. Always wear appropriate eye and hand protection and follow machine guarding requirements per OSHA and facility safety standards. Do not exceed the spindle speed and feed recommendations appropriate for the workpiece material and bit diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.098 inches (Wire Size 40)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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: M42 Cobalt High-Speed Steel\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\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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 559\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO\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: 50895\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732466041138,"sku":"50895","price":44.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5d92ffa42f8cc5bf33a2250f5ce0e7b_0e82c425-2288-4fe2-a8ee-e895cb731355.jpg?v=1788743096","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50895-screw-machine-drill-bit-0-098-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
