Hertel S-74148297 Combo Drill Countersink Size 2 Hss

Product Description

The HERTEL S-74148297 is a combination drill and countersink tool designed to drill a pilot hole and countersink in a single pass. Built from high-speed steel (HSS) with a bright, uncoated finish, it is engineered for countersinking applications where clean, accurate entry angles are required. The body diameter measures 3/16 inches, the drill point diameter is 5/64 inches, and the overall length is 1-7/8 inches. The tool features a 60-degree included angle and a plain cutting edge style. It is sized as a trade size 2 and cuts in the right-hand direction. Machinists, tool and die technicians, and precision fabricators install this type of tool in drill presses and CNC setups.

This combo drill countersink is suited for light-duty countersinking tasks in metalworking, fabrication, and general machining environments. The double end type extends tool life by offering two usable ends. The non-tapered, non-aircraft-style construction makes it a straightforward general-purpose countersink for standard shop and production work. It is sold individually and is appropriate for use in both manual and machine-driven applications where a consistent countersink angle is needed.

Installation Notes

This tool is installed by machinists and fabricators in drill presses, mill spindles, or CNC machining centers. Secure the tool firmly in a drill chuck or collet before operation and confirm the spindle is fully stopped before making any tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain cut quality. Follow applicable shop safety protocols and machine manufacturer guidelines for speed and feed selection.
