The present invention relates to a blade (100) used for a grinding head (10) for a grinding work of a road pavement. The blade (100) comprises: a main body (101) formed in a disk shape; and a plurality of blade units protruding outside by enclosing a rim of the main body (101). The blade units comprises: a plurality of left blade units (110) inclined towards a left side; and a plurality of right blade units (120) inclined towards a right side. The left blade units (110) and the right blade units (120) are individually arranged, and the blade is able to easily obtain a structure wherein an entire pavement is smoothly cut at a fixated depth. The blade also enables stable work by preventing a grinding device from being separated, and having a small impact even if the grinding device has a low weight and a small size. |
