Cleveland C02950 Jobber Drill Bit No. 49 0.073 Inch Hss

Product Description

The CLEVELAND C02950 is a wire-gauge jobber-length drill bit sized at No. 49 (0.0730 inches decimal equivalent) designed for general-purpose drilling in a wide range of materials. Built from high speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree split point and a fast spiral flute configuration that promotes efficient chip evacuation. The straight cylindrical shank measures 0.0730 inches in diameter and 1.0 inch in length, while the overall length is 2.0 inches with a 1.0-inch flute length. This bit is manufactured to ASME B94.11M standards and carries an ANSI specification designation. Machinists, maintenance technicians, and toolroom professionals are the primary users of this size range.

The C02950 is suited for drilling operations in steel, aluminum, non-ferrous metals, and wood. The fast spiral flute geometry aids chip clearance at higher feed rates, making it a reliable choice for production environments and repair-shop use alike. Its compact overall length keeps it stiff enough for accurate spot entry without a pilot, and the web-thinned, tapered web design reduces thrust requirements during entry. This is a single-piece packaged item sold in multiples of 10.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill chuck or collet system sized for 0.0730-inch straight shanks. Secure the shank fully and verify chuck runout before drilling. Apply cutting fluid appropriate to the workpiece material to maximize tool life. De-energize or lock out the machine before changing tooling.
