Hertel 334-207070 Countersink 5/8 in 90 Deg 4 Flute Carbide

Product Description

The HERTEL 334-207070 is a solid carbide countersink designed for producing precise conical seat profiles in metal and other hard materials. With a 90-degree included angle and a 5/8 inch head diameter, it cuts clean, burr-free chamfers suitable for flathead fastener seating and edge deburring. The straight-cylindrical shank measures 5/8 inch in diameter for secure chuck retention. Four flutes provide balanced cutting action and efficient chip evacuation, making it a reliable choice for production drilling operations and maintenance work in machine shops and fabrication environments.

This countersink is suited for use in CNC machining centers, drill presses, and hand-held drill motors where consistent countersink geometry is required. It is commonly applied to ferrous and non-ferrous metals, plastics, and composite materials when a 90-degree seat angle is specified by fastener or design requirements. Machinists, toolmakers, and maintenance technicians in manufacturing and fabrication settings are the primary installers and operators of this tool.

Key Features

• 90-degree included angle for standard flathead fastener countersinking
• 5/8 inch head diameter provides sufficient clearance for common screw head sizes
• Solid carbide construction delivers extended tool life in hard and abrasive materials
• 4-flute geometry promotes smooth cutting action and reduced chatter
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a standard 90-degree countersink for use with drill presses, CNC machining centers, and handheld drill motors accepting a 5/8 inch straight-cylindrical shank. No specific compatible model or system data was provided in the product input.

Installation Notes

This tool is installed and operated by machinists, toolmakers, or maintenance technicians familiar with metalcutting operations. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation. Use appropriate cutting speeds and feeds for the workpiece material and carbide tooling to prevent premature wear or chipping. Inspect the cutting edges for damage before each use and replace the tool if chipping or edge wear is detected.
