Hertel H-81154L02060 Combo Drill Countersink Hss

Product Description

The HERTEL H-81154L02060 is a No. 2 combination drill and countersink designed for simultaneous center drilling and countersinking in a single operation. Made from high-speed steel with a bright, uncoated finish, this tool features a 3/16-inch body diameter, a 118-degree drill point angle, and an 82-degree included angle for countersinking. The 6-inch overall length qualifies it as a long-length tool, giving machinists and tool and die professionals extra reach in deep setups. It is suited for use in manual mills, CNC machining centers, and drill presses where accurate center spotting and chamfering are required before turning or drilling operations.

This combo drill countersink is intended for metalworking applications where a precise center hole and countersink must be produced in one pass. The plain cutting edge style and double-end configuration make it practical for production environments where tool life and cycle time matter. It is commonly used by machinists in job shops, manufacturing facilities, and maintenance departments working with ferrous and non-ferrous metals. The 5/64-inch drill point diameter and 5/64-inch drill point length deliver consistent, accurate spotting geometry.

Installation Notes

Installation and use should be performed by qualified machinists familiar with center drilling operations. Secure the workpiece and verify spindle runout before engaging the tool. Use appropriate cutting fluid for the material being machined to manage heat and extend tool life. Inspect the cutting edges before each use and replace the tool if chipping or wear is present.
