US 2025/0114849 A1 · CUTTING TOOL AND TOOL HOLDER FOR A ROTARY CUTTING DEVICE

Abstract

The present disclosure relates to a cutting tool system comprising a tool holder and a cutting tool. The tool holder includes a base for mounting onto a rotary drum or disc and a body for removably coupling to the cutting tool. The cutting tool is for size-reducing a material and has a first side and a second side. The cutting tool includes a plurality of cutting edges that are selectively moveable into and out of a cutting path of the rotary drum or disc. The first and second sides each have at least one cutting edge, such that each of the first and second sides are configured to be a leading side of the cutting tool during use. This allows the cutting tool to be rotated and/or reversed, such that a single cutting tool provides several cutting edges and increases the wear or erosion life thereof.

A cutting tool system comprising:

a tool holder comprising a base for mounting onto a rotary drum or disc and a body;
and
a cutting tool for size-reducing a material, the cutting tool having a first side and a second side and being configured to couple to the body of the tool holder, the cutting tool comprising a plurality of cutting edges that are selectively moveable into and out of a cutting path of the rotary drum or disc, wherein the first side and the second side each have at least one of the plurality of cutting edges, such that each of the first side and the second side are configured to be a leading side of the cutting tool.

A cutting tool for mounting onto a rotary drum or disc for shredding a material, the cutting tool having a first side and a second side each configured to be a leading side of the cutting tool, each of the first side and the second side comprising:

a cutting side having cutting surfaces and an abutting surface positioned between the cutting surfaces;
a side opposing the cutting side;
opposing relief surfaces adjacent to the cutting side;
opposing support surfaces extending between the opposing relief surfaces;
and
opposing cutting edges at an apex of a given one of the opposing relief surfaces and an adjacent one of the cutting surfaces;
wherein the side opposing the cutting side of the first side and the side opposing the cutting side of the second side are adjacent and coupled at 90° relative to each other such that a given one of the opposing relief surfaces on the first side is on a same side of the cutting tool as a given one of the opposing support surfaces on the second side of the cutting tool.
