Hertel 18324 Countersink 3/4 in 82 Deg 6 Flute Hss

Product Description

The HERTEL 18324 is a single-body countersink designed for producing clean, accurately angled seat profiles in metal and similar materials. Built from high speed steel, it delivers consistent cutting performance across repeated use in production and maintenance environments. The 82-degree included angle matches the standard seating geometry for flat-head fasteners commonly used in aerospace, metalworking, and general fabrication. With six flutes, the tool distributes cutting load evenly, reduces chatter, and produces a smooth finish on the countersunk surface. The 3/4-inch head diameter and 3/4-inch straight cylindrical shank allow straightforward mounting in standard drill presses, CNC machining centers, or hand-held power tools with compatible chuck capacity.

This countersink is suited for use in machine shops, fabrication facilities, and maintenance operations where flat-head fastener seating is required. The 82-degree angle makes it particularly appropriate for aerospace-standard and general-purpose applications where that included angle is specified. Machinists, tool-and-die technicians, and maintenance mechanics typically use this type of tool on steel, aluminum, and other ferrous and non-ferrous workpieces. It is sold individually and is compatible with standard straight-shank toolholders and drill press chucks sized to accept a 3/4-inch shank.

Key Features

• 82-degree included angle matches flat-head fastener seating standards for general and aerospace applications
• Six flutes distribute cutting forces evenly, minimizing chatter and improving surface finish
• High speed steel construction provides durability and heat resistance for metal cutting
• 3/4-inch straight cylindrical shank fits standard drill press chucks and toolholders
• 3/4-inch head diameter provides adequate coverage for common flat-head fastener sizes

Compatibility

Designed for use with standard straight-shank toolholders and drill press chucks that accept a 3/4-inch diameter shank. Suitable for countersinking operations on metal workpieces where an 82-degree included angle is required.

Installation Notes

Installation and use of this countersink should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the straight cylindrical shank firmly in a properly sized chuck or toolholder before operation, and verify that the workpiece is clamped or fixtured to prevent movement. Always power down and de-energize the machine before changing or inspecting tooling. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve cut quality.
