A debarking tooth of a debarking machine comprises a platform secured to an outer surface of a rotary member rotatably arranged in a wood container; a blade tip plate detachably attached to the platform; an arbitrary number of engage projections formed on one of the platform and the blade tip plate in a tapered shape so that a horizontal area of each engage projection becomes gradually smaller toward a distal end; an arbitrary number of engage recesses formed on the other one of the platform and the blade tip plate in a tapered shape so that a horizontal area of each engage recess becomes gradually smaller toward a bottom, the engage recesses being respectively engageable with the engage projections; and a fixing screw member driven toward the platform from the blade tip plate with the engage projections engaged with the engage recesses, thereby securely attaching the blade tip plate to the platform.
