summary Some dental prostheses are formed by machining. The purpose of this study was to evaluate the dental high‐speed cutting behaviour of free‐machining titanium (Ti), the ease in cutting of which is metallurgically improved. Weight‐load cutting tests were performed on commercial pure Ti and free‐machining Ti, using a diamond point and a carbide burr. It became evident that the cutting effectiveness of two rotary cutting instruments on free‐machining Ti was superior to that on commercial pure Ti due to the formation of accelerated cut debris. Cutting of free‐machining Ti resulted in less damage of the carbide burr, compared with the cutting of commercial pure Ti. These results suggest that free‐machining Ti is a suitable workpiece for dental Ti‐based machined prostheses.
