Hertel 333-002070 Carbide Countersink 3/16 in 90 Degree 3 Flute

Product Description

The HERTEL 333-002070 is a solid carbide countersink designed for precision chamfering and countersinking operations in metalworking and fabrication applications. It features a 90-degree included angle with a 45-degree centerline angle, a 3/16 inch head diameter, and three flutes for smooth, controlled cutting action. The bright, uncoated carbide construction delivers hardness and wear resistance suited for production environments where tool life and dimensional accuracy matter. This tool is installed and used by machinists, tool-and-die technicians, and maintenance trades working with drill presses, CNC machining centers, or hand-held power tools requiring consistent countersink geometry.

This countersink is suited for creating clean, chamfered seat profiles on fastener holes in metal workpieces. The straight cylindrical shank allows direct chucking in standard drill chucks or collet holders without additional adapters. With a 3/16 inch shank diameter matching the head diameter, it fits compact tool holders and is appropriate for light-duty countersinking in tight clearance areas. It is a single-end tool with no pilot, making it versatile across hole diameters within its cutting range. Typical applications include deburring, chamfering drilled holes, and preparing seating surfaces for flat-head fasteners.

Key Features

• 90-degree included angle (45-degree centerline angle) for standard flat-head fastener seat geometry
• 3/16 inch head diameter and 3/16 inch straight cylindrical shank for compact tool holder compatibility
• Three-flute design for smooth cutting action and reduced chatter
• Solid carbide construction with bright, uncoated finish for hardness and wear resistance
• Right-hand cut, single-end configuration with no pilot for versatile hole-size application
• Weighs 0.3 pounds — lightweight for benchtop and portable tool use

Compatibility

Designed as an OEM-style solid carbide countersink for use in standard drill chucks and collet holders accepting a 3/16 inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trained trade technicians familiar with rotational cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits to prevent premature edge wear. Power down the machine and allow all rotation to stop completely before changing or inspecting the tool. Always wear appropriate eye protection and follow shop-floor safety standards when operating countersinking tools.
