Hertel 336-205050 Countersink 3/8 in 60 Degree 6 Flute Carbide

Product Description

The HERTEL 336-205050 is a solid carbide countersink designed for precision chamfering and deburring operations in metal fabrication, machining, and tooling applications. It features a 3/8 inch head diameter with a 60-degree included angle and six flutes, which produce smooth, chatter-resistant cuts and clean entry angles in a wide range of materials. The straight cylindrical shank measures 3/8 inch in diameter, allowing direct mounting in standard drill chucks or collet-style holders. This countersink is sized for production and maintenance machinists who need consistent, repeatable results at the spindle.

This countersink is suited for use on drill presses, CNC machining centers, and manual mills where accurate seat angles and clean hole preparation are required. The 60-degree angle is commonly specified for fastener seating in aluminum, steel, and composite work. The six-flute geometry distributes cutting load evenly, reducing vibration and extending tool life in high-cycle applications. It is sold individually and is appropriate for both shop production environments and field maintenance tooling setups.

Key Features

• 60-degree included angle for standard fastener chamfer and deburring work
• Six flutes for smooth, low-vibration cutting and improved surface finish
• Solid carbide construction for hardness and wear resistance across a range of workpiece materials
• 3/8 inch straight cylindrical shank for compatibility with standard chucks and collets
• Compact overall profile suited for tight-clearance drilling setups

Compatibility

Designed as a direct-mount countersink for use with 3/8 inch straight-shank tool holders, drill chucks, and collets on drill presses, CNC machining centers, and manual milling machines.

Installation Notes

This tool is installed by machinists and tooling technicians. Secure the shank fully in the chuck or collet to the rated gripping depth before operation, and verify runout before engaging the workpiece. Always power down and lock out the spindle before changing or adjusting the tool. Use appropriate cutting speeds and feeds for the workpiece material to avoid carbide fracture from excessive feed pressure.
