Hertel 18036 Countersink 1 in 60 Degree Hss Straight Shank

Product Description

The HERTEL 18036 is a single-flute high speed steel countersink designed for creating clean, accurately angled seat profiles in metal and similar materials. With a 1-inch head diameter and a 60-degree included angle, this tool produces precise countersunk recesses for flathead fasteners and deburring operations. The straight cylindrical shank measures 1/2 inch in diameter, providing secure chuck engagement in standard drill presses, mills, and hand-held power tools. Licensed machinists, tool-and-die workers, and general metalworking professionals will find this countersink well-suited to production and maintenance applications where repeatable seat geometry is required.

This countersink is appropriate for use in machine shop and fabrication environments, including general metalworking, maintenance repair operations, and light manufacturing. The single-flute geometry reduces chatter and delivers a smoother finish on the countersunk seat compared to multi-flute designs, making it a practical choice when surface finish at the recess is important. It is intended for stationary machine use as well as handheld drill applications where the 1/2-inch straight shank is compatible with standard toolholders and drill chucks.

Key Features

• 1-inch head diameter for full-seat coverage on larger flathead fastener applications
• 60-degree included angle for standard countersunk fastener profiles
• Single-flute design reduces chatter and improves surface finish at the recess
• High speed steel construction provides good wear resistance across a range of workpiece materials
• 1/2-inch straight cylindrical shank fits standard drill chucks and toolholders

Compatibility

Designed as a standard single-flute countersink for use in drill presses, milling machines, and handheld power tools accepting a 1/2-inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists or metalworking technicians using standard drill press, milling machine, or handheld power equipment. Secure the workpiece before operation and confirm the spindle or chuck is fully tightened on the 1/2-inch shank before starting the machine. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Always wear appropriate eye protection and follow shop safety procedures when operating rotary cutting tools.
