Hertel 336-012050 Countersink 1-1/2 in 60 Deg 6 Flutes

Product Description

The HERTEL 336-012050 is a single-end countersink designed for precision countersinking operations in metal fabrication, machining, and assembly work. It features a 1-1/2 inch head diameter and a 60-degree included angle (30-degree centerline angle), making it suited for standard fastener seat preparation. The tool has 6 flutes for smooth chip evacuation and a clean finish on the countersunk surface. The straight-cylindrical shank measures 3/4 inch in diameter for secure chuck engagement. The bright, uncoated alloy steel construction handles general-purpose countersinking without the need for coatings, keeping regrinding straightforward. Machinists, tool-and-die technicians, and metalworking professionals are the typical end users.

This countersink is used in general metalworking, production machining, and maintenance repair operations where standard 60-degree countersinks are required. It is suited for preparing holes to accept flat-head fasteners, deburring drilled holes, and chamfering operations on ferrous and compatible non-ferrous materials. The 6-flute design reduces chatter at moderate spindle speeds, making it appropriate for both manual and CNC machine tool setups. No pilot is included, so it operates as a free-cutting pilotless countersink in standard drill press, lathe, or milling machine applications.

Key Features

• 1-1/2 inch head diameter for wide countersink coverage
• 60-degree included angle for standard flat-head fastener seating
• 6 flutes for reduced chatter and improved surface finish
• 3/4 inch straight-cylindrical shank for secure machine chuck holding
• Bright, uncoated alloy steel construction — easy to regrind
• Single-end, pilotless design for free-cutting versatility

Compatibility

Designed as an OEM-style replacement or direct procurement countersink for use in standard drill press, lathe, or milling machine setups requiring a 3/4 inch straight shank and a 60-degree countersink geometry.

Installation Notes

Installation and operation should be performed by qualified machinists or metalworking professionals familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Always verify spindle speed is appropriate for the tool diameter and workpiece material before beginning the cut.
