Use a flat file and a depth gauge jointer to lower all gauges uniformly. Use a 0.6 mm (0.025 in.) depth gauge jointer. After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining drive links with the edge of the file.

See Figures 65 and 66.

Depth gauges must be adjusted with the flat file in the same direction the adjoining cutter was filed with the round file. Use care not to contact cutter face with flat file when adjusting depth gauges.
