Wood drilling bit balling sticking an approach

 1.lower specific gravity and viscosity of the arix core drill bit, with a large amount of circulating pump.
2, with a hammer hanging.
3, with the jar shock.
4, injected acid king stuck agent.
Share, is a way of life throughout.
Allegedly, these ribs located at the end of the drill shallow cooling belt grooves can significantly improve the cutting performance of the drill bit. Cooling liquid may cover the entire drill tip, effectively cooling the drill bit and the interface with the workpiece, and to prevent chips from clogging. The new bit design also increases the thickness of the material behind the cutting edge, to improve the stability of the drill bits for wood. Radial ribs arranged so that the drilling process with a more fluid, minimizes vibration, which can improve processing quality holes. The first delivery of the DC170 drill aspect ratio of 16 and 20.
