重型螺旋鉆

Simply put, an auger is a spiral-shaped tool that is used to drill holes into the ground and other surfaces or materials.The spiraling metal shaft with a blade at the end of the device is known as a “flighting”. The flighting rotates to scrape, cut, or siphon out drilled materials. Debris from the drilled materials (e.g., soil, ice) moves along the flighting and out of the hole during the blade’s rotation.
