The swing type cutting tip including abrasive particles has a specific arrangement capable of enhancing the cutting efficiency of the abrasive particles, and thus achieving an enhancement in cutting performance and an increase in lifespan. The cutting tip includes a plurality of abrasive particles to cut a workpiece while swing. At least a part of the abrasive particles are arranged in the form of abrasive particle groups. Each abrasive particle group is constituted by at least two abrasive particles. At least a part of the abrasive particles of the abrasive particle groups are overlapped in a cutting direction.
