Hertel 334-001050 Carbide Countersink 1/8 in 60 Deg 4 Flute

Product Description

The HERTEL 334-001050 is a solid carbide countersink designed for producing clean, precise conical seat holes in metal and other hard materials. With a 1/8-inch head diameter and a 60-degree included angle, this tool is sized for small-diameter fastener preparation work. The 4-flute configuration promotes smooth cutting action and reduces chatter, which is critical when working with tight tolerances. The straight cylindrical shank measures 1/8 inch in diameter, making it compatible with standard collet chucks and drill press setups. Machinists, tool and die workers, and precision fabricators use this countersink for deburring, chamfering, and countersink seat formation on small-scale components.

This countersink is suited for benchtop drill presses, CNC machining centers, and manual mill setups where a small-footprint tool is required. Its carbide construction makes it appropriate for ferrous and non-ferrous metals, hardened alloys, and abrasive materials where high-speed steel tooling would wear prematurely. The compact head diameter makes it particularly useful for countersinking pilot holes in tight clearance areas or on small workpiece features where larger tools cannot access.

Key Features

• 1/8-inch head diameter for small-fastener countersink preparation
• 60-degree included angle matches standard fastener seat geometry
• 4-flute design reduces vibration and improves surface finish
• Solid carbide construction for extended tool life in hard and abrasive materials
• Straight cylindrical shank seats securely in collet chucks and drill press holders

Compatibility

Designed as an OEM-style replacement or direct-use countersink for machining applications requiring a 1/8-inch head diameter, 60-degree angle tool with a straight cylindrical shank in standard collet or drill chuck toolholding systems.

Installation Notes

This tool is installed and operated by machinists and precision fabricators using standard collet chucks or drill press keyless chucks. Secure the shank fully in the collet or chuck before operation and verify runout before engaging the workpiece. Always power down and lock out the machine spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed selection based on material and tool diameter.
