Abstract
A pair of replaceable, identical cutter inserts are provided for a cutter head assembly of a sign engraving machine. The cutter inserts have inside edges formed at an angle of approximately 15.degree. from a cutter tip axis. The inside edges of the cutter insert overlap to form an 'X' when installed in the cutter head for sign engraving operations. Chips migrate up the inside edges from the cutter tips and are exhausted from the cutting area.
