Clean and deburr the main oil passage holes 

The main oil passage holes of the engine are narrow and long, with some having a length-to-diameter ratio greater than 28. There are multiple cross holes inside the holes, and there may be burrs remaining. To solve this problem, an abrasive-containing high-efficiency hole brush is used. Through high-speed rotation and reciprocating motion, it can effectively remove impurities and burrs in the oil passage. The brush material is soft, and it will not cause air hole blockage like that caused by sand wheels or grinding belts.
