Built to Series 1501-TT specs, it features a 5\/16-inch diameter with a 135-degree split point that reduces walking and lowers thrust force on entry. A titanium nitride (TiN) coating extends surface hardness and wear resistance for longer service life between sharpenings. The straight cylindrical shank measures 0.3125 inches in diameter, and the overall length is 4.5 inches. Two spiral flutes evacuate chips efficiently, keeping the cut clear during continuous drilling operations. This bit is suited for production and maintenance drilling where cobalt alloy construction provides an edge over standard high-speed steel.\u003c\/p\u003e\u003cp\u003eThe C66017 is intended for drilling alloy steel, carbon steel, cast iron, aluminum, and other non-ferrous metals. Its right-hand cutting direction and web-thinned, tapered web configuration make it effective in drill press, CNC, or hand-drill applications across light manufacturing, maintenance, and fabrication environments. The 3-3\/16-inch flute length accommodates typical jobber-depth holes without extension. Machinists, tool-and-die workers, and general maintenance technicians are the primary users of this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-inch cobalt construction for heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walking and cutting thrust\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web improves chip clearance and reduces feed force\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design evacuates chips continuously during drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill bit suitable for use in standard drill press, CNC, and hand-held drilling applications requiring a 5\/16-inch diameter cobalt bit with a straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Secure the straight shank fully in the chuck before operation and verify that the workpiece is clamped to prevent movement. No coolant-through capability is present on this bit, so external coolant or cutting fluid should be applied manually when drilling hard alloys or at high feed rates. Follow applicable shop safety practices and ANSI standards for drill press and hand-drill operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Aluminum, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1501-TT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: CLE-LINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C66017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52125121544498,"sku":"C66017","price":66.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f39e51de1c6a1a60d2c2c649f1c53fe_9d31bc5f-6079-4abb-9c51-d4a713438f18.jpg?v=1790087361","url":"https:\/\/voomisupply.com\/products\/cle-line-c66017-cobalt-jobber-drill-bit-5-16-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
