Hertel 336-003080 Carbide Countersink 1/4 in 6 Flute

Product Description

The HERTEL 336-003080 is a solid carbide countersink designed for creating clean, accurately angled seat profiles in metal and hard materials. It features a 1/4 inch head diameter, a 100 degree included angle, and 6 flutes that distribute cutting load evenly for smooth surface finish and reduced chatter. The straight cylindrical shank measures 1/4 inch in diameter, making it compatible with standard drill chucks and collet holders. This tool is suited for deburring, chamfering, and countersinking operations in machine shop, maintenance, and production environments. Machinists and tooling technicians are the primary users.

This countersink is appropriate for use in CNC machining centers, manual drill presses, and hand-held drilling equipment where a 1/4 inch straight shank is accepted. The 100 degree included angle suits flathead fastener seating in harder substrate materials. It is sold individually and is appropriate for both low-volume repair work and higher-frequency production countersinking tasks where carbide longevity is preferred over high-speed steel alternatives.

Key Features

• 1/4 inch head diameter for small-diameter countersink applications
• 100 degree included angle for flathead screw seating in hard materials
• 6 flutes provide even cutting load distribution and improved surface finish
• Solid carbide construction for extended tool life compared to HSS
• Straight cylindrical 1/4 inch shank fits standard chucks and collet holders

Compatibility

Designed for use with standard drill chucks and collet-style toolholders accepting a 1/4 inch straight cylindrical shank. Suitable for countersinking operations in metal, hardened alloys, and similar hard substrate materials.

Installation Notes

This tool is installed by machinists or tooling technicians into a drill chuck or collet holder. Ensure the machine spindle is fully stopped and the tool is securely clamped before beginning any operation. Set spindle speed appropriate for carbide tooling and the workpiece material. Avoid side-loading the shank, as carbide is brittle and can fracture under lateral stress.
