It is ground to a 135-degree split-point angle for self-centering starts without a center punch. The oxide and gold coating reduces friction and extends tool life in hard-material applications. With a 2-inch overall length and a 1-inch spiral flute, this bit is built for short, precise drilling tasks. It runs right-hand cutting with a regular spiral and a straight-cylindrical shank. Machinists, maintenance mechanics, and fabricators use this bit in production and repair work where tight tolerances and hard materials are the norm.\u003c\/p\u003e\n\u003cp\u003eThe CD50251 is designed primarily for drilling stainless steel, superalloys, and titanium — materials that generate high heat and work-harden quickly. The cobalt construction handles elevated temperatures that would degrade standard high-speed steel bits. The 135-degree split point reduces thrust force and walking on smooth or hardened surfaces. Maximum drilling depth is 1 inch, making this well suited for thin stock, brackets, flanges, and structural components common in mechanical and industrial maintenance settings. The straight-cylindrical shank seats directly in standard drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 55 diameter: 0.0670 inches (1.70 mm) for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers on contact, reducing walking and setup time\u003c\/li\u003e\n  \u003cli\u003eCobalt construction withstands the heat generated by stainless steel and superalloy drilling\u003c\/li\u003e\n  \u003cli\u003eOxide and gold coating lowers friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 2-flute regular spiral design clears chips efficiently in deep passes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard keyless and keyed drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to -0.0005 to +0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for wire gauge 55 jobber drill bits in the CD50 series. The straight-cylindrical shank is compatible with any standard drill chuck sized to accept a 0.0670-inch shank. Intended for use in drill presses, CNC machines, and hand-held electric drills where cobalt tooling is specified for hard-material applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and verify runout before drilling, particularly in CNC or drill-press setups where bit deflection will affect hole tolerance. When drilling stainless steel or titanium, use a cutting fluid rated for hard metals to manage heat buildup and protect the cutting edge. Reduce feed pressure compared to carbon steel drilling to avoid work-hardening the entry surface. Inspect the split point for chipping after use on abrasive or hardened stock, and redress or replace when point geometry degrades.\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: 55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Gold\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1 inch\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: 0.0670 inches (2.00 mm)\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: Stainless Steel, Superalloys and Titanium\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: CD50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD50251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51738420085042,"sku":"CD50251","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/befbfcc753dd7854ba2beffedaa4d33d_1cdadcdf-2f7e-4d53-a01e-943163d984ee.jpg?v=1788799311","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd50251-cobalt-jobber-drill-bit-55-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
