Pier Hole Protectors
An auger is a drilling device, or drill bit, used for making holes in the ground. It usually includes a rotating helical screw blade called a "flighting" to act as a screw conveyor to remove the drilled out material. The rotation of the blade causes the material to move out of the hole being drilled.
A4 Augers have as standard 65mm round drive hubs and they are also available in 50.8mm round, 50.8mm hex and 57mm square drive hubs.
A4 augers are available in 5 different tooth and pilot styles:
Earth (E): suitable for soft ground and sand
Tungsten Carbide (TC): suitable for soft ground and sand with better wear properties than Earth
Multi Facet Tungsten (MFT): best all rounder; suitable for hard ground conditions including clay
Earth/Rock Combo (RC): suitable for harder ground conditions including clay, shale, mudstone, fracturable rock, sandstone, asphalt and concrete
Dedicated Rock (DR): suitable for fracturable and non fracturable rock.
A4 augers suit machines from 800kg to 5 tonnes and torque ratings to 5000Nm.
