Hertel 336-205060 Countersink 3/8 in 82 Degree 6 Flute Carbide

Product Description

The HERTEL 336-205060 is a solid carbide countersink designed for precision chamfering and deburring of drilled holes in metalworking and machining applications. It features a 3/8 inch head diameter with an 82-degree included angle, which is the standard angle for flat-head fastener seating in North American applications. The 6-flute geometry produces a smooth finish and helps reduce chatter during the cut. The straight cylindrical shank measures 3/8 inch in diameter, allowing it to seat securely in standard drill chucks and collet holders. This tool is suited for machinists, tool-and-die shops, and fabrication professionals working with ferrous and non-ferrous materials.

This countersink is used in production machining, maintenance and repair operations, and general fabrication environments where consistent, clean countersink profiles are required. The 82-degree angle makes it well matched to flat-head machine screws and socket-head fasteners with that included angle specification. It is appropriate for use in CNC machining centers, drill presses, and hand-held power drill setups where a collet or chuck accepts a 3/8 inch straight shank. Both vertical and horizontal machine orientations are common installation scenarios.

Key Features

• 82-degree included angle for flat-head fastener seating compatibility
• 6-flute design for smooth finish and reduced chatter
• Solid carbide construction for durability and wear resistance
• 3/8 inch straight cylindrical shank fits standard chucks and collets
• 3/8 inch head diameter for precise chamfer sizing

Compatibility

Designed as an OEM-style countersink for use in standard 3/8 inch straight-shank toolholders, drill chucks, and collet systems on drill presses and CNC machining centers requiring an 82-degree countersink profile.

Installation Notes

This countersink is installed and operated by machinists and toolroom professionals. Secure the straight shank firmly in a drill chuck or collet holder before use and verify runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid or lubrication as required by the workpiece material to preserve tool life.
