A cutter tool comprises a tool holder (10), a cutting bit (12) mounted in a bore (14) of the tool holder, and a washer (40) disposed between the tool holder and the cutting bit. The washer is a conical (Belleville) washer which makes annular line contact with a shoulder (28) of the cutting bit, and with an edge (46) of the bore of the tool holder, in order to effectively seal-out fines from the bore.
