Abstract
A cutting-tool holder (1) used for grinding includes a holder body (10) including a pair of pinching pieces (11, 11) biased to each other; and a pair of handgrips (30, 30) provided on the holder body (10) which sets the pair of pinching pieces (11, 11) apart from each other by applying force to the handgrips (30, 30). The holder body (10) may further include a connecting portion (12) with a nearly C-shaped cross section which connects base end parts (11c, 11c) of the pinching pieces (11, 11). Each handgrip (30) may be configured so that one end part (30a) is fixed to the pinching piece (11), the middle part penetrates the connecting portion (12), and the other end part extends away from the pinching piece (11).
