Hertel 18125 Countersink 2 in 82 Degree 6 Flute Hss

Product Description

The HERTEL 18125 is a high speed steel countersink designed for producing accurate, clean conical recesses in metal and other materials. With a 2-inch head diameter and an 82-degree included angle, this tool is suited for standard flat-head fastener seating applications across a range of materials. The 6-flute configuration promotes smooth cutting action and reduces chatter, making it a reliable choice for production and maintenance environments. The straight-cylindrical shank measures 1 inch in diameter, providing solid tool holder engagement on drill presses, milling machines, and similar equipment.

This countersink is appropriate for metalworking applications in both shop and field settings. The 82-degree included angle matches the seating geometry of standard flat-head machine screws and is commonly used in aerospace, manufacturing, and general machining work. A 2-1/8-inch shank length provides adequate reach for most standard setups. Licensed machinists and tool-room technicians are the typical installers and operators of this tool.
