A bite control ring assembly includes a depth control ring having a first end, a second end opposite the first end, and a gap disposed between the first and second ends; a tool holder having a capture joint and a tool holder interface opposite the capture joint, wherein the first end of the depth control ring is received within the capture joint; and a cutting tool having a cutting tool interface and a cutting surface disposed on a side of the cutting tool opposite the cutting tool interface, wherein the tool holder interface includes a V-shaped surface and the cutting tool interface includes a V-shaped surface that has a reciprocal shape to the tool holder interface such that the tool holder interface receives the cutting tool interface.

A shredder blade assembly includes a rotor having a plurality of pockets. The shredder blade assembly further includes a plurality of knife blades which are each disposed in one of the plurality of pockets. The knife blades are secured into the pockets by a compression force applied from a periphery of the rotor and in a direction towards a shaft aperture in the rotor.

A material processing tool assembly includes a tool for material processing having a base section and a processing section extending from the base section; and a tool mounting block mountable on an outer surface of a support base. The mounting block has a base surface and a tool mounting surface intersecting the base surface. The base surface has a protuberance extending away therefrom and spaced apart from the tool mounting surface to define a tool receiving gap between the protuberance and the tool mounting surface. The base section of the tool is snugly received in the tool receiving gap between the tool mounting surface and the protuberance in abutment with the tool mounting surface, the processing section of the tool extending past the protuberance. A displaceable material processing head and method of mounting a material processing tool to a mounting block secured to a displaceable head are also discussed.
