Manufactured from M42 cobalt high-speed steel, this bit carries a titanium nitride (TiN) coating that improves surface hardness and extends cutting life in tough materials. The 135-degree split point reduces walking on entry and requires less feed force, making it well suited for production drilling in hard alloys, stainless steel, and hardened steels. A parabolic flute geometry promotes efficient chip evacuation over the full 2.625-inch flute length, reducing heat buildup during deep-hole operations. The overall length is 3.875 inches with a straight-cylindrical shank diameter of 0.2280 inches.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in machine-shop, maintenance, and fabrication environments where standard high-speed steel bits wear prematurely. Wire size No. 1 corresponds to a decimal diameter of 0.2280 inches, placing it in the 0.2000 to 0.2500 inch size range. It is appropriate for use in drill presses, lathes, CNC machining centers, and hand-held portable drills with a compatible chuck. The right-hand cut orientation suits the majority of standard rotating-spindle equipment. Machinists, millwrights, maintenance technicians, and industrial tradespeople are the primary installers and users of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for high red-hardness and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends cutting life and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip evacuation and reduces heat in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration maintains rigidity while improving cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards for consistent dimensional accuracy\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 with any standard drill press, CNC machining center, or portable drill chuck that accepts a 0.2280-inch straight-cylindrical shank.

Secure the shank fully in the chuck before operation and verify that spindle speed is appropriate for the workpiece material and bit diameter. Do not exceed the rated cutting parameters for the workpiece material, and allow adequate chip clearance during deep-hole drilling. Always wear appropriate eye protection and follow applicable workplace safety standards when operating rotary cutting tools.\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. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\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\u003eFinish \/ Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075T\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\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\u003eWeight\u003c\/strong\u003e: 0.4 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: C16612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693382533426,"sku":"C16612","price":34.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72ec45573fd3d9ebc084e87d2026b024_921a8321-2400-45d9-b64c-3fc00e20577d.jpg?v=1788311518","url":"https:\/\/voomisupply.com\/products\/cleveland-c16612-cobalt-drill-bit-no-1-wire-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
