Built from M42 cobalt high-speed steel with a gold oxide coating, it delivers extended tool life in abrasive and hard workpiece materials. The bit measures 3.25 inches overall length with a 2.125-inch flute length and a straight-cylindrical shank of 0.1610 inches in diameter, matching its wire size 20 cutting diameter. A 135-degree split point reduces walking and allows drilling without a center punch in most applications. The parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup during deep-hole operations. At 0.2 pounds, it is a single-piece, individually packaged bit intended for professional trade use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for metalworking applications across maintenance, fabrication, and production environments. Its cobalt M42 construction makes it appropriate for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals where standard HSS bits wear prematurely. The right-hand cut and parabolic flute design support use in standard drill presses, CNC machining centers, and hand drills operating at appropriate feeds and speeds for the workpiece material. It is a heavy-duty grade bit commonly used by machinists, millwrights, pipefitters, and general metalworking tradespeople.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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 reduces drill walking and lowers entry force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry improves chip evacuation and reduces heat in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eGold oxide finish provides additional lubricity and surface protection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust requirements at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a wire size 20 jobber-length drill bit compatible with standard 3-jaw drill chucks accepting a 0.1610-inch straight shank. Suitable for use in drill presses, CNC machining centers, and portable hand drills. Conforms to ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized drill chuck and verify the shank is fully seated and secured before operation. Select feed rate and spindle speed appropriate for the workpiece material and bit diameter per standard machining references. Cobalt bits are brittle compared to standard HSS — avoid side loading or using the bit as a lever during extraction. Use cutting fluid when drilling stainless steel or cast iron to reduce heat and extend tool life.\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: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.130 inches\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: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075\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: 0.2 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695400649010,"sku":"C16522","price":20.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e5c5f3ef72ce91f3407fbab0f1888ec_1ff77cbe-f8bd-4fe6-b392-9198de75c587.jpg?v=1788334612","url":"https:\/\/voomisupply.com\/products\/cleveland-c16522-jobber-drill-bit-wire-20-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
