Description
The Robert Charles Deburring Tools Through Hole – Zero Flute – Imperial 60° – 1/2 Head Diameter is a purpose-built deburring tool designed for finishing through holes. Its Zero Flute geometry supports fast, accurate deburring, chamfering, and light countersinking from narrow access points, making it a reliable choice for engineers, machinists, and production shops.
