Title: Innovations by Hans-Peter Dohse

Introduction

Hans-Peter Dohse is a notable inventor based in Grafenau, Germany. He has made significant contributions to the field of tool design, particularly in the development of innovative drilling tools. With a total of 3 patents to his name, Dohse's inventions reflect his expertise and commitment to enhancing drilling efficiency.

Latest Patents

One of his latest patents is a tool chuck designed for hammer drills. This tool chuck features an inner sleeve and an axially slidable outer sleeve that concentrically surrounds the inner sleeve. The inner sleeve is equipped with an open leading end that is adapted to receive a tool shank. The shank is clamped within the inner sleeve through a snap action upon insertion. The design allows for selective torque and axial impact to be imparted to the tool chuck from the hammer drill's drive. Additionally, the tool shank includes a radially outwardly opening recess and at least one axially extending groove, which facilitates torque transmission through a formation in the inner sleeve.

Another significant invention by Dohse is a drilling tool that comprises a drilling shaft member and a crown drilling member with multiple cutting edges. This crown drilling member is detachably mounted on the shaft member, along with a center drilling member that has a further cutting edge. The design includes elements that limit the drilling depth when the center drilling member is in use. This innovative feature compels the operator to remove the center drilling member after creating a guiding groove, thereby enhancing drilling efficiency.
