Hertel 331-007560 Countersink 5/8 in 82 Deg Alloy Steel

Product Description

The HERTEL 331-007560 is a single-flute countersink designed for creating beveled recesses in workpieces ahead of flathead fastener installation. It features a 5/8-inch head diameter and an 82-degree included angle, making it well-suited for standard countersinking applications in alloy steel, cast iron, and glass-reinforced plastic. The straight-cylindrical shank measures 3/8 inch in diameter for secure chuck retention. With a bright, uncoated finish and right-hand cutting direction, this tool delivers consistent performance in manual and machine drilling setups. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of tooling.

This countersink is intended for use in metalworking and fabrication environments where precise fastener-seat geometry is required. It is rated for use in alloy steel, cast iron, and glass-reinforced plastic substrates. The single-flute design is appropriate for applications where controlled chip evacuation and smooth finish are priorities. No pilot is included, so the operator must guide the tool freehand or with a drill guide for accurate placement. It is sold individually and is a current catalog item.

Key Features

• 5/8-inch head diameter with an 82-degree included angle for standard fastener-seat geometry
• Single-flute design promotes smooth cutting action and controlled chip removal
• 3/8-inch straight-cylindrical shank compatible with standard drill chucks and tool holders
• Right-hand cutting direction for use with conventional clockwise-rotation spindles
• Bright, uncoated finish suitable for general-purpose metalworking without heat buildup concerns
• Rated for alloy steel, cast iron, and glass-reinforced plastic material applications

Compatibility

Designed as an OEM-style replacement or direct-use countersink for metalworking operations requiring an 82-degree, single-flute tool in alloy steel, cast iron, or glass-reinforced plastic materials.

Installation Notes

Install the 3/8-inch shank into a properly sized drill chuck or collet and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during cutting. Apply appropriate cutting fluid for the material being worked when required. Follow shop safety protocols and applicable OSHA machining guidelines during use.
