E-Z Burr Tool Co.'s Component Micro Series tools are for deburring and chamfering microholes from 0.057" to 0.092" in diameter. A tool's solid arbor can be replaced without changing the HSS blade and vice versa. The blades and arbors can be changed while the tool, which also includes a holder, is still in the machine. The cutting angle can also be changed for more or less aggressive cutting.
