Cleveland C73433 Jobber Length Drill Bit No 5 Hss

Product Description

The CLEVELAND C73433 is a jobber-length twist drill bit in wire gauge No. 5, corresponding to a decimal diameter of 0.2055 inches. Made from high-speed steel with a bright uncoated finish, it features a 118-degree split point and a regular spiral flute ground to NAS 907 Type A standards. The split point reduces walking on entry and lowers thrust requirements, which matters on production floors and in field drilling applications. This is a heavy-duty grade bit suited for machinists, maintenance technicians, and fabricators who need consistent hole quality in aluminum and comparable workpiece materials.

The C73433 fits standard jobber-length drilling applications in light manufacturing, MRO maintenance, and fabrication shops. Its 2.5-inch flute length and 3.75-inch overall length make it compatible with most 3-jaw drill chucks on benchtop drill presses, hand drills, and CNC drilling setups. The straight-cylindrical shank seats securely in standard chucks without the need for adapters. Primary workpiece material designation is aluminum, though the HSS construction handles many non-hardened metals at typical machining speeds.

Key Features

• Wire gauge No. 5 diameter: 0.2055 inches with a tolerance of -0.0007 to 0.0000 inches
• 118-degree split point reduces thrust and minimizes bit walking on entry
• High-speed steel construction with bright uncoated finish for general-purpose use
• Regular spiral, 2-flute design for efficient chip evacuation
• Web-thinned tapered web for improved cutting efficiency
• Meets NAS 907 Type A specification, heavy-duty grade

Compatibility

Designed as a jobber-length replacement or stock drill bit for standard straight-shank drill chucks; primary workpiece material designation is aluminum per NAS 907 Type A classification.

Installation Notes

Secure the straight-cylindrical shank fully in a drill chuck before operation and verify chuck key is removed prior to starting the machine. Disconnect or lock out power to the drill press before changing bits per standard OSHA lockout-tagout procedures. Do not exceed the recommended surface footage for high-speed steel in the workpiece material being drilled. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling at sustained high feeds or in deeper holes.
