A cutter drum for pavement profiler machines has readily replaceable hardened tooth holders bolted to mounting bases. The teeth and holders function over extended periods of time without excessive wear. The tooth holder mounting bases, which have overlapping portions through which a bolt extends to hold the tooth holder in position, are formed of softer steel readily weldable to the cutter drum surface. Complementary surfaces on each of the tooth holders and an adjacent mounting base resist forces acting on the teeth during cutting operations.
