Abstract
A coolant collet assembly has a collet body and a cutter. The collet body has an outer end, an inner end, an annular groove, multiple external slits, multiple internal slits, and multiple coolant channels. The external slits and the internal slits are in a staggered arrangement. Each coolant channel is defined longitudinally in the collet body around the cutter hole, is converged radially toward the outer end, and has an end communicating with a respective one of the internal slits and an opening formed in the outer end. The cutter is inserted in the cutter hole. The coolant may flow through the coolant channels of the collet body and is guided to the heating point of the working cutter with the converged coolant channels.
