The HERTEL 334-306060 is a solid carbide countersink designed for producing clean, accurate countersunk holes in metal, composite, and similar materials. With a 1/2 inch head diameter and an 82-degree included angle, this tool conforms to flat-head fastener seat standards common in aerospace and precision machining applications. The four-flute geometry distributes cutting load evenly, reducing chatter and improving finish quality at the countersink seat. The straight cylindrical shank measures 1/2 inch in diameter, making it compatible with standard drill chucks and collet holders used by machinists and toolroom technicians.
This countersink is suited for use on CNC machining centers, drill presses, and manual milling setups where consistent countersink depth and angle are required. The 82-degree included angle matches the seating geometry for 82-degree flat-head screws and bolts, a specification frequently called out in aerospace, sheet metal, and general fabrication work. Machinists and precision metalworking professionals are the primary installers and operators of this tooling.
Designed as an OEM-style replacement or direct tooling option for machining setups requiring a 1/2 inch, 82-degree, four-flute carbide countersink with a straight cylindrical shank.
This countersink is installed and operated by machinists and toolroom professionals. Secure the straight cylindrical shank firmly in a properly sized collet or drill chuck before operation. Ensure the spindle is fully stopped and the machine is powered down before changing or inspecting tooling. Run at manufacturer-recommended speeds for the workpiece material and carbide tooling to prevent premature wear or chipping.
