The bit is manufactured from M42 cobalt steel and coated with TiAlN (titanium aluminum nitride) for elevated heat resistance and extended tool life in demanding drilling operations. The 135-degree split point starts on contact without a center punch and reduces walking on flat or curved surfaces. Overall length is 2 inches with a 1-inch parabolic flute, right-hand cut, and straight-cylindrical shank. Licensed machinists, tool and die technicians, and metal fabricators will find this bit well-suited to production and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThe C11449 is designed for drilling cast iron, stainless steel, and similarly tough ferrous and hard-alloy workpieces. The parabolic flute geometry promotes efficient chip evacuation in deep-hole drilling and reduces heat buildup in the cut zone. At 0.0730-inch diameter, this bit is commonly used for tapping preparation, precision hole sizing, and fine-pitch fastener clearance work in metal fabrication, aerospace component maintenance, and industrial machine shops. Coolant-through is not supported; external coolant application or cutting fluid is recommended when drilling stainless or work-hardening alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for elevated red-hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in high-temperature cutting applications\u003c\/li\u003e\n  \u003cli\u003e135-degree split point enables self-centering starts without a center punch\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry improves chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and cutting torque requirements\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M and DIN 338 standards for jobber-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber-length drill bit for any standard drill press, CNC machining center, or hand drill chuck accepting a 0.0730-inch straight-cylindrical shank.

Secure the shank fully in a chuck and verify runout before beginning a cut. Apply cutting fluid or external coolant when drilling stainless steel or other work-hardening alloys to prevent premature coating breakdown. Inspect the cutting edge for wear or chipping between uses, as small-diameter cobalt bits are susceptible to breakage under excessive feed pressure or lateral loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 49\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: M42 Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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: 0.0730 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\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\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 Material\u003c\/strong\u003e: Cast Iron, Stainless Steel\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\u003eSeries\u003c\/strong\u003e: 2075A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: C11449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722408231218,"sku":"C11449","price":22.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/623cbae05e0a5cc2d3a40d440b2a3831_abfa302a-ddc9-44f1-baa0-9b2874edb18c.jpg?v=1788590684","url":"https:\/\/voomisupply.com\/products\/cleveland-c11449-jobber-drill-bit-no-49-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
