Built from M42 cobalt high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and heat resistance in demanding production and maintenance applications. It carries a No. 50 wire gauge size, equating to 0.0700 inches in diameter, with an overall length of 2 inches and a 135-degree split point. The parabolic flute geometry promotes efficient chip evacuation, and the web-thinned, tapered web construction reduces thrust requirements at entry. Licensed HVAC technicians, plumbers, machinists, and electrical contractors reach for cobalt TiN-coated bits when drilling stainless, hardened steel, cast iron, or other tough substrates that defeat standard HSS tooling.\u003c\/p\u003e\n\u003cp\u003eThis bit suits light-duty through heavy-duty drilling tasks in industrial, commercial, and field service settings. The straight-cylindrical shank fits standard 3-jaw drill chucks without requiring a special collet or adapter. With a 1-inch flute length and 1-inch shank length, the C16664 is sized for use in handheld drills, drill presses, and CNC machining centers where a No. 50 wire size hole is required. Typical applications include pilot holes, through-holes in sheet metal, and precision work on electrical enclosures, HVAC components, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction resists heat and wear in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating extends surface hardness and reduces friction\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required entry thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design improves chip clearing and reduces clogging in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web minimizes cutting resistance at the drill tip\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in any standard drill chuck accepting a 0.0700-inch straight shank, including handheld electric drills, drill presses, and CNC spindles requiring a No. 50 wire gauge bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank firmly in a calibrated 3-jaw chuck before operation and verify chuck runout is within acceptable tolerance to maintain hole accuracy. Always wear eye protection and secure the workpiece to prevent rotation during drilling. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to extend bit life, noting that this bit does not have through-coolant capability. Inspect the cutting edges and TiN coating for wear before each use; a dull or chipped edge on cobalt tooling should be replaced rather than reworked in field conditions.\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: No. 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0700 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\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\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075T\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695090204978,"sku":"C16664","price":20.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72ec45573fd3d9ebc084e87d2026b024_8300a63f-7343-4007-a327-dc672626b822.jpg?v=1788331225","url":"https:\/\/voomisupply.com\/products\/cleveland-c16664-jobber-drill-bit-no-50-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
