Hertel 331-207050 Carbide Countersink 5/8 in 60 Degree

Product Description

The HERTEL 331-207050 is a single-flute carbide countersink designed for producing clean, accurate countersunk holes in metal and other hard materials. With a 5/8 inch head diameter and a 60-degree included angle, this tool delivers precise angular seat geometry suited to flathead fastener applications. The straight cylindrical shank measures 5/8 inch in diameter, providing a secure grip in standard drill chucks or collet holders. Carbide construction gives this countersink the hardness and wear resistance required for production work on ferrous and non-ferrous stock. It is appropriate for use on CNC machining centers, drill presses, and manual mills where consistent countersink geometry is required.

The 331-207050 is intended for metalworking and machining environments where tight angular tolerances on countersunk seats are critical. The single-flute geometry reduces cutting forces and improves chip evacuation, making it well suited for harder materials and applications where chatter or surface finish are concerns. Machinists, tool and die makers, and CNC operators working in job shops, manufacturing facilities, and maintenance settings will find this countersink applicable for both production runs and one-off precision work requiring a 60-degree seat profile.

Key Features

• 60-degree included angle for standard flathead fastener seat geometry
• 5/8 inch head diameter provides adequate coverage for common fastener sizes
• Single-flute design promotes chip clearance and reduces cutting forces in hard materials
• Carbide construction offers superior hardness and wear resistance over high-speed steel alternatives
• Straight cylindrical shank at 5/8 inch diameter fits standard chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct-use countersink for machining setups requiring a 5/8 inch diameter, 60-degree single-flute carbide tool with a straight cylindrical shank. Verify chuck or collet capacity accepts 5/8 inch shank diameter before installation.

Installation Notes

Installation is performed by machinists or CNC operators using a drill press, mill, or machining center. Ensure the machine spindle is fully stopped and the chuck or collet is clean and undamaged before mounting the tool. Set spindle speed appropriate for carbide tooling and the workpiece material to avoid thermal shock or chipping of the cutting edge. Do not exceed the rated geometry limits of the countersink by applying side loads or using it as a reamer.
