Hertel 334-201060 Countersink 1/8 in 82 Deg 4 Flute Carbide

Product Description

The HERTEL 334-201060 is a solid carbide countersink designed for producing clean, accurate countersunk holes in metal, composites, and similar hard materials. With a 1/8-inch head diameter, an 82-degree included angle, and 4 cutting flutes, this tool delivers smooth surface finishes and consistent hole geometry suited to flathead fastener seating. The straight cylindrical shank measures 1/8 inch in diameter, making it compatible with standard collet chucks and drill presses. Machinists and toolroom technicians use this countersink where precision and tool longevity are required on small-diameter work.

This countersink is sized for small-bore applications common in precision machining, sheet metal fabrication, and aerospace-adjacent work where flathead screws require a flush or sub-flush seat. The 82-degree included angle matches the standard for imperial flathead machine screws, making it a practical everyday tool for production and repair environments. Its compact 1/8-inch head and shank dimensions suit work held in CNC machining centers, manual drill presses, and benchtop machines alike.

Key Features

• 82-degree included angle matches standard imperial flathead fastener geometry
• Solid carbide construction for extended tool life on hard and abrasive materials
• 4-flute design promotes smooth cutting action and improved surface finish
• 1/8-inch straight cylindrical shank fits standard collets and chucks
• Compact 1/8-inch head diameter suited to small-diameter precision work

Compatibility

Designed as an OEM-style replacement and standard tooling option for machines accepting 1/8-inch straight cylindrical shank cutting tools, including CNC machining centers, benchtop drill presses, and manual milling setups requiring small-diameter countersinks.

Installation Notes

Installation and use of this countersink should be performed by a qualified machinist or toolroom technician. Secure the shank fully in the collet or chuck before operation and verify runout before cutting. Power down and lock out the machine spindle before changing or adjusting the tool. Do not exceed the recommended speed and feed range for the workpiece material and tool diameter.
