IMPROVEMENT OF ABRASIVE DISC

摘要

PROBLEM TO BE SOLVED: To provide a rotation sanding disc whose worked part can be observed and cooled during work. SOLUTION: Accessories of an angle grinder contain a disposable abrasive disc 100 having a big opening 101 for ventilation/observation, wherein the disc is used together with an elastic retaining plate having a ventilation hole. An opening of either or both of the members is shaped so as not to engage with a protrusion from a working surface and so as to facilitate airflow over the working surface during use.
