Cleveland C46114 Countersink 1/2 in 82 Degree 1 Flute Hss

Product Description

The CLEVELAND C46114 is a single-flute high speed steel countersink designed for creating conical seat recesses in metal workpieces. It features a 1/2 inch head diameter, an 82-degree included angle (41-degree centerline angle), and a 1/4 inch straight cylindrical shank. An oxide coating helps reduce friction and extend tool life in production environments. The single-flute geometry produces a smooth, chatter-resistant finish, making it well suited for precise countersinking work in carbon steel and cast iron. Machinists, tool-and-die workers, and fabricators typically use this tool in drill press or CNC setups.

This countersink is intended for use on carbon steel and cast iron stock in metal fabrication, maintenance, and production drilling operations. The 82-degree included angle matches the standard angle used for flat-head fastener seating in many industrial and structural applications. It is a no-pilot, single-end design, meaning it countersinks without a guide pilot and is not reversible. The 1/4 inch shank fits standard drill chucks and collet systems commonly found in manual drill presses, lathes, and CNC machining centers.

Key Features

• 1/2 inch head diameter for medium countersink recesses
• 82-degree included angle for standard flat-head fastener seating
• Single flute design reduces chatter and produces a smooth finish
• High speed steel construction for durability in carbon steel and cast iron
• Oxide coating minimizes friction and improves tool longevity
• 1/4 inch straight cylindrical shank for broad chuck and collet compatibility

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Fits standard drill chucks and collet holders accepting a 1/4 inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists and metalworking tradespeople. Secure the shank fully in the chuck or collet before use and confirm the workpiece is firmly clamped. Use appropriate cutting fluid or coolant when countersinking carbon steel to reduce heat buildup. Inspect the cutting edge for wear or chipping before each use and replace the tool if the edge is compromised.
