Cleveland C73424 7/16 in Hss Jobber Length Drill Bit

Product Description

The CLEVELAND C73424 is a jobber-length drill bit designed for general-purpose drilling in metal fabrication, maintenance, and industrial applications. Manufactured from high speed steel with a bright uncoated finish, it features a 118-degree split point that reduces walking on entry and improves hole accuracy. The bit measures 7/16 inch (0.4375 inches) in diameter with an overall length of 5.5 inches and a spiral flute length of 4-1/16 inches. It meets NAS 907 Type A standards and is rated as a heavy-duty grade bit, making it a reliable choice for professionals who drill frequently and need consistent performance.

This bit is suited for drilling aluminum and similar workpiece materials in both shop and field environments. The regular spiral flute design promotes efficient chip evacuation, reducing heat buildup and extending tool life. The straight-cylindrical shank at 7/16 inch diameter fits standard drill chucks found on benchtop drill presses, hand drills, and magnetic-base drills. It is appropriate for use by machinists, maintenance technicians, plumbers, electricians, and HVAC technicians who need a dependable jobber-length bit for everyday hole-making tasks.

Installation Notes

A licensed machinist or qualified trade technician should secure the shank fully in the chuck before operation and verify chuck key removal prior to starting the drill. Always power down and de-energize the drill press or tool before changing bits. Wear appropriate eye protection and secure the workpiece firmly to prevent rotation during drilling. Do not exceed the recommended speed range for the workpiece material and bit diameter.
