Hertel 336-207050 Carbide Countersink 5/8 in 60 Deg 6 Flute

Product Description

The HERTEL 336-207050 is a solid carbide countersink designed for creating clean, accurately angled entry chamfers in metal, composite, and hard material workpieces. The tool features a 60-degree included angle and a 5/8-inch head diameter, making it well suited for deburring drilled holes and preparing seats for flat-head fasteners. With six flutes, it distributes cutting load evenly and produces a smooth finish in a single pass. The straight cylindrical shank measures 5/8 inch in diameter, providing a secure grip in standard drill chucks and toolholders. Machinists and toolroom technicians working on precision components will find this countersink a direct fit for production and maintenance applications.

This countersink is intended for use in machine tool setups including drill presses, CNC machining centers, and manual mills where controlled chamfering and deburring are required. Its carbide construction makes it appropriate for harder workpiece materials where high-speed steel tooling wears prematurely. It is sold and packaged individually, making it suitable as a direct replacement or addition to an existing countersink set in a shop or field service kit.

Key Features

• 60-degree included angle for standard flat-head fastener seat preparation and chamfering
• 5/8-inch head diameter provides adequate coverage for a range of hole sizes
• Six flutes distribute cutting forces evenly and reduce chatter for a smoother finish
• Solid carbide construction delivers extended tool life in hard and abrasive materials
• Straight cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or standard addition for machine tool applications requiring a 5/8-inch, 60-degree, six-flute carbide countersink with a straight cylindrical shank.

Installation Notes

This countersink is installed by a machinist or toolroom technician in a drill chuck, collet, or toolholder rated for the 5/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Confirm runout and tool stick-out are within acceptable tolerances before starting a cut. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain surface finish quality.
