Kyocera CM-1000-55 1in Shank Indexable 45° Chamfer Mill

The Kyocera CM-1000-55 is a new, indexable carbide-insert chamfer mill from Kyocera Precision Tools designed for 45° chamfering and deburring operations on CNC machining centers. The tool body is steel with a black oxide/nitride surface treatment and accepts two indexable carbide inserts secured by Torx-style clamping screws; a Torx wrench is included in the blue plastic case. The part number decodes as: CM = Chamfer Mill series, 1000 = 1.000 in (1-inch) shank diameter, 55 = 55° included angle insert geometry (producing a 45° chamfer lead angle when referenced from the workpiece face). Made in the United States per the label, this tool is suited for chamfering, countersinking, and deburring on steel, cast iron, aluminum, and non-ferrous materials where consistent, repeatable edge preparation is required on production CNC equipment.
