Union Ceramic Cutting Tool is an inorganic material,
die-pressed and sintered using very fine and pure raw

materials with fine microstructure.

Insert Tip Since the Union ceramic inserts are prepared by HIP
process to condense completely, it has high thermal
shock resistance, excellent fracture toughness and

distinguished wear resistance through HIP.
