Hertel 336-005050 Carbide Countersink 3/8 in 60 Degree 6 Flute

Product Description

The HERTEL 336-005050 is a solid carbide countersink designed for precision chamfering and countersinking operations in metalworking and fabrication applications. The tool features a 3/8-inch head diameter, a 60-degree included angle, and 6 flutes for smooth cutting action and reduced chatter. The 1/4-inch straight cylindrical shank provides a secure, consistent grip in standard drill chucks and collet holders. Weighing just 0.05 pounds, this compact tool is suited for benchtop drill press work, CNC machining centers, and hand-held power drill applications where accurate seat angles are required.

This countersink is built for right-hand cut operation and is rated for use on alloy steel, cast iron, and glass-reinforced plastic. The bright, uncoated carbide construction delivers reliable performance across these materials without the need for specialized coatings. It is a single-end tool with no pilot included, making it appropriate for use where a pre-drilled hole guides the cutting head. Machinists, tool-and-die technicians, and maintenance mechanics in industrial and job-shop environments will find this a straightforward drop-in addition to standard tooling setups.

Key Features

• 3/8-inch head diameter with a 60-degree included angle (30-degree centerline angle) for standard fastener seat preparation
• 6-flute carbide construction reduces chatter and improves finish quality on harder materials
• 1/4-inch straight cylindrical shank fits standard chucks and collet holders
• Right-hand cut direction compatible with conventional drill press and CNC spindle rotation
• Bright, uncoated finish suitable for alloy steel, cast iron, and glass-reinforced plastic
• Single-end, no-pilot design for use in pre-drilled hole applications

Compatibility

Designed for countersinking operations on alloy steel, cast iron, and glass-reinforced plastic. Fits any standard drill chuck or collet holder accepting a 1/4-inch straight cylindrical shank.

Installation Notes

Secure the shank firmly in a drill chuck or collet before operation and verify runout is within acceptable limits for the application. Always power down and lock out the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid or coolant when machining ferrous materials to extend tool life. Follow shop safety standards and wear appropriate eye and hand protection during all cutting operations.
