The HERTEL 334-003050 is a solid carbide countersink designed for producing clean, accurate conical recesses in metal and other hard materials. With a 0.25 inch head diameter, a 60-degree included angle, and four flutes, this tool delivers consistent cutting geometry and efficient chip evacuation in demanding machining applications. The straight cylindrical shank measures 0.25 inches in diameter for standard collet or chuck mounting. It is suited for machinists, tool-and-die shops, and production environments where precise countersinking at tighter tolerances is required.
This countersink is used in metalworking and manufacturing applications where 60-degree conical seats are needed, such as deburring drilled holes or preparing fastener seats in ferrous and non-ferrous workpieces. The four-flute configuration reduces chatter and improves surface finish compared to single-flute designs. It is appropriate for use in CNC machining centers, manual mills, and drill press setups across job shop and production environments.
Designed as an OEM-style replacement or direct-use countersink for standard 0.25 inch straight-shank toolholders in CNC and manual machining setups requiring a 60-degree countersink profile.
Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a collet or drill chuck rated for the spindle speed being used. Ensure the machine is fully powered down and the spindle is locked before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish quality.
