Hertel 336-003060 Countersink 1/4 in 82 Degree 6 Flute Carbide

Product Description

The HERTEL 336-003060 is a solid carbide countersink designed for creating clean, accurately angled seat profiles in a range of materials. It features a 1/4-inch head diameter, an 82-degree included angle, and six flutes that promote smooth chip evacuation and a consistent finish. The straight cylindrical shank measures 1/4 inch in diameter for secure chuck retention. With a bright, uncoated finish, this countersink is suited for use in drill presses, CNC machines, and hand-held power tools where precise countersinking is required. It is a single-end tool without a pilot, making it appropriate for applications where the pilot hole is already established or guided separately.

This countersink is rated for use in alloy steel, cast iron, and glass-reinforced plastic, making it a versatile option for metalworking and composite fabrication environments. The right-hand cutting direction and six-flute geometry reduce chatter and produce a consistent countersink seat for fastener flush-mounting. It is well suited for production shops, maintenance facilities, and field service work where material variety demands a reliable carbide cutting tool.

Key Features

• 1/4-inch head diameter with 82-degree included angle for standard fastener seat geometry
• Six flutes for reduced chatter and smooth material removal
• Solid carbide construction for durability in hard and abrasive materials
• Straight cylindrical 1/4-inch shank for broad chuck compatibility
• Bright, uncoated finish — no coating buildup concerns during regrinding
• Single-end design, no pilot included

Compatibility

Designed for countersinking operations in alloy steel, cast iron, and glass-reinforced plastic. Fits any standard drill chuck or collet system accepting a 1/4-inch straight cylindrical shank.

Installation Notes

This tool is installed by machinists and metalworkers in drill press, mill, or hand-drill setups. Ensure the workpiece is securely clamped before operation and the spindle speed is appropriate for carbide tooling in the target material. Always wear eye protection when operating rotary cutting tools. Inspect the cutting edges for chips or wear before each use — carbide tools can fail suddenly if used past serviceable condition.
