Apparatus for reducing a log to chips comprising a rotatable cutter head adapted for translational movement relative to a log, and carrying a cutting element, such element comprising a length of open-ended tubular or segment there of material having a leading beveled cutting edge which attacks the log to cut away a chip which travels away from the log through the tubular cutting element. The cutting element is matingly and removably received in an appropriate recess in the cutter head thereby providing for mounting of the cutting element on the cutter head with a preselected segment of the leading edge of the cutting element exposed to attack the log.
