Abstract

A rotary cutter drum (1) that includes a barrel (2) around the external periphery (3) of which is welded at least one helical vane (4). A multiple of notches (5) are provided at locations where a mineral cutting tool (S) is required. Each notch (5) receives a portion of a tool holder (6), which is welded in place. The tool holder (6) provides an aperture to receive, and releasably retain, the shank (7) of a mineral cutting tool (8), with the terminal end (16) of the shank (7) being exposed. Each notch (5) has an opening (15A) opposite the exposed, terminal end (16) of a shank (7). The opening (15A) has an extended length toward the barrel (2), by a distance at least approximating to the length of the shank to define a shank-receiving void or chamber.
