Robert Charles Countersinks 90° - Deburring Tool - Through Hole - Zero Flute - Imperial - 1.1/4 Head Diameter

The Robert Charles Countersinks 90° Deburring Tool is a precision tool designed for fast, accurate deburring, edge breaking, and light countersinking of through holes. Its zero-flute design delivers smooth, chatter-free cuts by reducing tool contact with the material, helping you produce clean edges and a high-quality surface finish.

Built for a wide range of materials, this imperial countersink features a 1-1/4 inch head diameter and a 90° countersink profile. The through-hole geometry promotes efficient chip evacuation and stable cutting performance, making it suitable for everyday workshop and production use on steels, aluminium, plastics, and non-ferrous metals.

• Zero-Flute Precision for Smooth Edges: Reduces tool contact with the material to minimize chatter, delivering cleaner edges and a superior surface finish.
• Through-Hole Optimized Deburring: Specifically designed for through-hole work with efficient chip evacuation to prevent clogging and downtime.
• Imperial 90° Countersink with 1-1/4" Head Diameter: Provides consistent chamfers and broad material compatibility across steels, aluminum, plastics, and non-ferrous metals.

By using this countersink, you can finish holes faster, reduce rework, and achieve reliable, repeatable edge quality across a wide range of projects. The zero-flute design minimizes chatter for a smoother finish, while efficient chip evacuation keeps holes clear and cutting stable across steels, aluminium, plastics, and non-ferrous metals. With its imperial sizing and sturdy build, you can count on consistent performance across materials and applications, whether you're a professional machinist, maintenance technician, or hobbyist.
