Hertel 331-120082 Countersink Set 5 Pc Solid Carbide

Product Description

The HERTEL 331-120082 is a 5-piece solid carbide countersink set designed for precision countersinking in metalworking and fabrication applications. Each countersink features a single-flute design and an 82-degree included angle, covering head diameters from 0.25 inches up to 1 inch. The uncoated solid carbide construction delivers consistent performance in ferrous and non-ferrous materials. The set stores in an included wood block, keeping each tool organized and protected between uses. Machinists, tool and die technicians, and production fabricators rely on this type of set for creating clean, accurate countersunk seat geometry in drilled holes.

This countersink set is suited for machine shop, production floor, and maintenance environments where multiple countersink diameters are needed without swapping tool holders frequently. The 82-degree angle matches standard flat-head fastener seat geometry used widely in metalworking. The range of five sizes from 0.25 to 1 inch head diameter covers the most common fastener seating tasks in light to medium fabrication. The wood storage block keeps the set accessible on a bench or in a tool cabinet drawer.

Key Features

• 5-piece set covering 0.25 to 1 inch head diameters
• 82-degree included angle matches standard flat-head fastener geometry
• Single-flute design for clean, chatter-reduced cutting

• Wood storage block included for organized bench or cabinet storage

Compatibility

Designed as a general-purpose countersink set for use in standard drill presses, CNC machining centers, and manual milling machines accepting straight-shank countersink tooling.

Installation Notes

Countersinks in this set should be installed by a qualified machinist following shop safety procedures. Secure the workpiece firmly before starting the spindle, and set spindle speed appropriate for the tool diameter and work material. Inspect each tool for chips or cracks before use. Do not exceed the tool's rated cutting conditions for solid carbide tooling.
