In addition to the various different patterns of auger bit, this tool is produced in a range of designs to drill through wood, as well as specialist auger bits that can drill through a variety of different materials both inside and outdoors.
Wood boring auger
This is the most common type of auger bit and can be used for drilling through thick pieces of wood to create channels for pipes or electrical cables.
Triple-fluted wood bit
Triple-fluted wood bits are aggressive, and designed to cut rapidly through wood stock where neatness is not a requirement.
Carbide-tipped auger bit
Similar to regular wood-boring augers, carbide-tipped augers are designed to be hard enough to cut through hidden nails, which would cause damage to other bits, meaning Carbide-tipped bits are likely to last for longer.
Concrete auger
Concrete augers are designed for use with hammer drills. They provide the advantages that you would associate with wood augers, such as efficient clearance of waste material and a neat bore hole, with the resilience of masonry drill bits.

Ice auger
Ice augers are enormous drill bits that can be powered by cordless drills through the use of an adaptor. They are used to drill holes in thick ice by fishermen.
Earth auger
Earth augers are large tools that are used to bore post holes into soil. They are often used in gardens. They need a driver more powerful than a cordless drill, such as a chainsaw motor, to work.For more information on the bit, see: What is an earth auger bit?
Sometimes, post holes need to be drilled through solid concrete or tarmac. In this case, earth augers with specially designed tips called ‘rock rippers’ are used to break through to the soil below.
