Hertel 334-307070 Carbide Countersink 5/8 in 90 Deg 4 Flutes

Product Description

The HERTEL 334-307070 is a solid carbide countersink designed for producing clean, accurate countersunk holes in metal and other hard materials. With a 5/8 inch head diameter and a 90-degree included angle, this tool generates the correct seat geometry for flat-head fasteners in a single pass. The 4-flute design provides smooth cutting action and improved chip evacuation compared to single-flute alternatives. The straight cylindrical shank measures 5/8 inch in diameter, making it compatible with standard drill chucks and collet holders. This countersink is used by machinists, tool-and-die workers, and maintenance professionals requiring consistent results in production or repair environments.

This countersink is suited for use in CNC machining centers, drill presses, and manual milling setups where precise countersink geometry is required. It is appropriate for creating fastener seats in steel, aluminum, cast iron, and similar workpiece materials. The carbide construction supports higher cutting speeds and extended tool life compared to high-speed steel alternatives, making it a practical choice for repetitive countersinking operations in shop or field environments.

Key Features

• 5/8 inch head diameter for standard flat-head fastener seat preparation
• 90-degree included angle matches common flat-head screw geometry
• 4-flute configuration improves chip flow and surface finish quality
• Solid carbide construction supports higher speeds and longer tool life
• Straight cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as a standard single-end countersink for use with drill chucks, collet holders, or quick-change tooling systems that accept a 5/8 inch straight cylindrical shank.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or trained maintenance personnel. Secure the shank firmly in a properly sized collet or chuck before operation and verify that spindle speed is appropriate for the workpiece material and tool diameter. Always power down and lock out the machine before changing or inspecting the tool. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
