Hertel 19316 Countersink 1-1/4 in 60 Degree 6 Flute Hss

Product Description

The HERTEL 19316 is a high speed steel countersink designed for producing clean, chamfered entry points in metal and other hard materials. With a 1-1/4 inch head diameter and a 60-degree included angle, it is suited for deburring, chamfering, and countersinking fastener seats in production and maintenance machining environments. The six-flute geometry distributes cutting load evenly, reducing chatter and improving surface finish. The straight-cylindrical shank measures 3/4 inch in diameter, making it compatible with standard drill press chucks and milling machine tool holders. Machinists, tool-and-die workers, and maintenance technicians install this tool in shop environments where precision chamfer angles are required.

This countersink is appropriate for use in drill presses, milling machines, and CNC machining centers wherever a 60-degree chamfer or fastener seat is needed. The 1-5/8 inch shank length provides adequate reach for most standard workholding setups. It is commonly used in metal fabrication, aerospace maintenance, and general manufacturing operations that require consistent, repeatable countersink geometry across multiple workpieces.

Key Features

• 1-1/4 inch head diameter for larger chamfer and countersink applications
• 60-degree included angle for standard fastener seat geometry
• 6-flute design reduces chatter and produces a smoother finish than single- or three-flute alternatives
• High speed steel construction provides toughness and wear resistance in steel and ferrous materials
• Straight-cylindrical shank compatible with standard chucks and collets
• 3/4 inch shank diameter suits common drill press and milling machine toolholding

Compatibility

Designed for use in drill presses, milling machines, and CNC machining centers with toolholding capable of accepting a 3/4 inch straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with rotary cutting tool safety. Secure the shank fully in a properly sized chuck or collet before operation and verify runout is within acceptable limits. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before engaging the cutter. Follow applicable OSHA and shop safety standards for speeds and feeds appropriate to the workpiece material.
