Cleveland C46116 Countersink 1/2 in 100 Deg 1 Flute Hss

Product Description

The CLEVELAND C46116 is a single-flute countersink designed for deburring and seat preparation in carbon steel and cast iron workpieces. Built from high speed steel with an oxide coating, it delivers controlled cutting action through a 100-degree included angle geometry. The 1/2-inch head diameter and 1/4-inch straight cylindrical shank make it a compact, purpose-built tool for countersinking fastener seats to spec. Right-hand cutting direction suits standard drill press and hand-drill setups. Machinists, fabricators, and maintenance technicians working in metal shops, job sites, and production environments reach for this type of tool when consistent countersink geometry is required.

This countersink is suited for use in carbon steel and cast iron applications where a 100-degree seat angle is required. The single-flute design reduces chatter and produces a cleaner finish on softer ferrous materials. It fits standard drill chucks and collet holders accepting a 1/4-inch shank. No pilot is included, so it relies on an existing drilled hole for centering. Typical use cases include fastener seat preparation, edge chamfering, and deburring on flat or near-flat workpiece surfaces in light manufacturing and maintenance-repair settings.

Key Features

• 1/2-inch head diameter with 100-degree included angle for standard fastener seat geometry
• Single-flute design minimizes chatter on ferrous materials
• High speed steel construction provides wear resistance across extended use cycles
• Oxide coating reduces friction and helps protect the cutting edge
• 1/4-inch straight cylindrical shank fits common drill chucks and collet holders
• Right-hand cutting direction compatible with standard rotary tooling setups

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Fits any drill press, hand drill, or CNC spindle accepting a 1/4-inch straight cylindrical shank.

Installation Notes

Install and remove this tool only while the spindle is fully stopped and power is disconnected or the chuck key is clear. Secure the shank firmly in the chuck or collet before operation to prevent slippage. Use appropriate cutting fluid for ferrous materials to extend tool life and improve finish quality. Always wear eye protection when operating rotary cutting tools.
