    Diamond-coated tools are intended for use in machining of carbon fiber reinforced plastics and dry processing of metals such as aluminum alloys and stainless steel. To guarantee the reliability of the coated tool, quantitative evaluation of the adhesion strength of the film onto the substrate is necessary. This study examines the development of an indentation tester for the evaluation of diamond film adhesion properties. The indenter point shape resembles that of the Rockwell C scale. This tester detects acoustic emissions continuously during the indentation of the diamond indenter against the film. This method defines the critical load to yield a crack on the film as the adhesion property of the film. Results show that the tester works satisfactorily for the quantitative evaluation of peeling or cracking strength of the film. The effect of the diamond material on the indenter lifetime is also discussed according to the longest lifetime for the binderless polycrystalline diamond.
