CUTTING TIP OF FRAME SAW AND FRAME SAW WITH THE CUTTING TIP
摘要:
A cutting tip for a cutting tool used to cut or drill a brittle workpiece such as stone, brick, concrete, or asphalt and a frame saw provided with the cutting tip are disclosed. 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.
