Cristone Bristle
Cross Hole Brush
detail

Bristles of cross hole brush are spread by the centrifugal force generated during rotation to remove burrs on sides and bottom of an inner hole. Suitable for electric grinders, air grinders or CNC.

    Ceramic fiber brush removes burrs by extending the brush rotation. You can remove the burrs of the side and the bottom of the radius cross hole.

1 mm brush is with one piece of ceramic fiber bristle as circled, so the brush will not spread out while rotation. Please increase the speed from the lowest slowly and do not exceed the maximum limit of 14,000 rpm to avoid the damage.

Attention
  1. Do not rotate till you reach the cross hole. 
  1. Adjust the rotation of the fiber brush to touch the burrs. Process the fiber brush forward and back. 
  1. It is very dangerous when you rotate the brush outside of the hole as it might break. Please make sure to stop the rotation before pulling out the fiber brush from the hole.
