A cutting bit and bit assembly for mounting at a cutting machine. The bit includes an axially tapered bit body having a recess extending axially within the body. The recess has an innermost region and a mouth region that is generally convex and/or tapered radially outward to abut a corresponding concave or tapered surface of a projection to secure the cutting bit at a holder body. An annular step is positioned within the recess at the mouth region to prevent dust and contaminant fluid or particles from passing axially into the recess.

Cutting bit and bit assembly

A cutting bit retaining assembly for mounting a cutting bit at a cutting machine includes a holder body having a through bore to receive a bit shaft. A retainer acts against the holder body and bit shaft and includes a first and second abutment member that provides a reliable and constant locking force between the body and the shaft.
