Hertel H-81185020500 Combo Drill Countersink Size 2 Hss

Product Description

The HERTEL H-81185020500 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built from high speed steel with a bright polished finish, this tool handles both operations without a tool change, making it a practical choice for machinists, tool-and-die technicians, and fabricators working on production or repair applications. The body diameter measures 3/16 inches, the drill point diameter is 5/64 inches, and the overall length is 5 inches. The 118-degree drill point angle and 60-degree included countersink angle are standard for general metalworking and center-drilling tasks.

This combo drill countersink is suited for use in metalworking environments where countersinking and center drilling are performed on ferrous and non-ferrous materials. The long-length design at 5 inches overall accommodates setups requiring extended reach. The plain cutting edge style and double end type make this a versatile tool for bench drill presses, milling machines, and CNC machining centers. It is sold and packaged as a single unit and is appropriate for both shop and field fabrication work.
