US Patent 7172373 Deburring tool with quick change knife

The invention relates to a deburring tool with a quick change knife, which is formed by at least two parts, namely a guide sleeve having a larger diameter and a center bore, and a base body that can be inserted in the center bore in an axial direction. The base body can be secured in the center bore. A knife groove is arranged on the base body that can receive the knife to be secured, forming a pivot support in the base body. Due to this special support, the knife can be easily exchanged even when the deburring diameters are small, for example, less than 4 mm, while still being able to absorb large deburring forces.
