Cleveland C46216 Countersink 5/8 in 60 Degree 4 Flute Hss

Product Description

The CLEVELAND C46216 is a high speed steel countersink designed for deburring and seat-cutting operations in metalworking applications. With a 5/8 inch head diameter and a 60-degree included angle, this tool produces clean, accurate countersunk recesses for flathead fasteners and chamfered hole entries. The four-flute design distributes cutting load evenly and helps maintain surface finish quality. An oxide coating provides added lubricity and corrosion resistance during dry or lightly lubricated cuts. The straight cylindrical 3/8 inch shank seats securely in standard drill press or milling machine chucks, making setup fast and repeatable for shop or field use.

This countersink is suited for use on alloy tool steel and cast iron workpieces in production machining, maintenance, and fabrication environments. It is a single-end tool without a pilot, so it relies on the operator or a drill press setup for centering. Right-hand cutting rotation matches standard drill press and milling spindle direction. Machinists, tool-and-die workers, and maintenance technicians working with steel and iron components will find this a direct-fit addition to a standard tooling inventory.

Key Features

• 5/8 inch head diameter with 60-degree included angle for standard flathead fastener seating
• Four flutes for balanced cutting action and improved finish quality
• High speed steel construction for durability in alloy tool steel and cast iron
• Oxide coating for added lubricity and corrosion resistance
• 3/8 inch straight cylindrical shank for compatibility with standard chucks
• Right-hand cut matches standard spindle rotation on drill presses and mills

Compatibility

Designed for countersinking operations in alloy tool steel and cast iron. Compatible with standard drill press and milling machine chucks that accept a 3/8 inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician. Secure the shank fully in the chuck and verify runout before cutting. Power down the spindle completely before changing or inspecting tooling. No pilot is included, so centering must be controlled through fixturing or a center-drilled guide hole to prevent walking.
