Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS bits. The 135-degree split point geometry allows self-centering penetration without a center punch, reducing walking on hard surfaces. A parabolic flute profile improves chip evacuation and reduces cutting torque. The straw oxide coating provides added lubricity and corrosion resistance. This bit is suited for production drilling environments where tool life and hole quality matter.\u003c\/p\u003e\u003cp\u003eThe C16559 is a heavy-duty bit sized at 1\/8 inch diameter with a 1-5\/8 inch flute length and 2-3\/4 inch overall length. It is well matched for drilling mild steel, alloy steel, stainless steel, and other hard ferrous workpieces in fabrication shops, maintenance and repair operations, and light manufacturing. The straight cylindrical shank fits standard drill chucks without adapters. Right-hand cutting direction is standard for conventional drill press and hand-drill use. This bit meets ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering starts and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip removal and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for lower cutting resistance and improved drill life\u003c\/li\u003e\n\u003cli\u003eStraw oxide coating provides lubricity and light corrosion protection\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for standard 1\/8 inch straight-shank drill chucks in drill presses, hand drills, and CNC drilling applications where Series 2075 cobalt bits are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight shank firmly in a keyed or keyless chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant when drilling hard steel to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use and replace the bit if chipping or significant wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1300 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\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt (M42 High-Speed Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: 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: 2075\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722145268018,"sku":"C16559","price":16.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18a7337d2cf3c178675acfc3a43aa4e5.jpg?v=1788586374","url":"https:\/\/voomisupply.com\/products\/cleveland-c16559-cobalt-jobber-drill-1-8-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
