Hertel 334-303060 Carbide Countersink 1/4 in 4 Flute 82 Deg

Product Description

The HERTEL 334-303060 is a solid carbide countersink designed for creating clean, accurate chamfered seat profiles in metal, composite, and hard plastic workpieces. With a 1/4 inch head diameter and an 82-degree included angle, this countersink is suited for flathead fastener seating in thinner materials and precision applications where controlled depth and surface finish are critical. The 4-flute geometry distributes cutting load evenly, reducing chatter and improving hole quality at moderate to high spindle speeds. The straight cylindrical shank measures 1/4 inch in diameter, making it compatible with standard collets and drill chucks.

This countersink is used in machining, fabrication, and assembly operations where consistent countersink geometry is required. It is well suited for bench drill presses, CNC machining centers, and hand-held drilling equipment where a 1/4 inch shank tool is appropriate. Typical applications include preparing fastener holes in sheet metal, aluminum extrusions, and structural components for flathead screws or rivets. Machinists, tool-and-die technicians, and fabricators working in production or maintenance environments will find this tool appropriate for repeat countersink operations.

Key Features

• 1/4 inch head diameter for compact, precise countersink profiles
• 82-degree included angle suited for standard flathead fastener seating
• 4-flute design reduces chatter and improves finish quality
• Solid carbide construction provides hardness and wear resistance for demanding materials
• Straight cylindrical shank fits standard 1/4 inch collets and drill chucks

Compatibility

Designed as a standard straight-shank countersink compatible with drill presses, CNC machining centers, and hand-held drilling equipment accepting a 1/4 inch cylindrical shank.

Installation Notes

This countersink should be installed in a properly sized collet or drill chuck and secured firmly before operation. Always power down and lock out equipment before changing tooling. Use appropriate spindle speeds for the workpiece material and carbide tooling to avoid overheating or chipping the cutting edges. Eye protection and appropriate guarding are required during operation per standard shop safety practices.
