Robert Charles Countersinks 90° - Deburring Tool - Through Hole - Zero Flute - Imperial - 1/2 Head Diameter

The Robert Charles Countersinks 90° Deburring Tool for Through Hole with Zero Flute delivers fast, precise deburring and light countersinking of through-hole features. Its zero-flute design minimizes contact with the workpiece, helping you achieve smooth edges and a high-quality finish with fewer passes. Ideal for steel, aluminum, plastics, and non-ferrous metals, this countersink is a reliable choice for machinists, fabricators, and hobbyists who demand consistent results across a range of materials.

Designed for through-hole work, it supports edge breaking and light countersinking in a single operation, maintaining stable cutting and efficient chip evacuation. The 90° geometry keeps the operation predictable and easy to control, making it suitable for both professional shops and DIY setups.

• Zero-flute design for smooth, chatter-free cutting: The zero-flute geometry reduces contact with the material, delivering cleaner edges with less vibration and longer tool life.
• Optimized for through-hole deburring and light countersinking: Specifically engineered to clean up inner hole edges, break sharp exits, and create consistent chamfers without over-cutting.
• Standard imperial head size (1/2 diameter) for reliable, repeatable results: The 1/2 head diameter fits common tooling setups and fixtures, providing predictable engagement and durability for everyday use.

In practice, this countersink helps you finish holes faster with less rework, delivering smooth edges, better surface quality, and repeatable results across projects. The robust build and precise geometry reduce downtime and keep your workflow moving, whether you’re in a busy workshop, a fabrication shop, or tackling a DIY project at home.
