Most augers dig about 3 feet deep, but an extension rod can be used to gain another 12 inches of depth. Deeper holes are required for deck footings and for footings on structures located in colder regions where the frost depth exceeds 3 feet.
What are the different types of auger bits? There are two types of auger drill bits: the Jennings bit has a spiral without a centre, while the solid-centre bit has a continuous straight central core. The Jennings bit is better at removing drill chips, but is more expensive to produce.
Which is better spade bit or auger bit? Auger bits generally drill cleaner holes with smoother sides and fewer splintering. They’re commonly used for general wood drilling in construction, woodworking in gardening, and many other areas. Spade bits drill holes with rougher sides and are therefore utilized in areas that will be covered.
What are the numbers on auger bits? The bit numbers are 4, 5, 6, 7, 8, 10, 12, 14, and 16. The 4, 5, 6 etc refers to the size in sixteenths. 4 is 4/16 or 1/4″. 6 is 6/16 or 3/8″.
Can an auger bit be sharpened?
How is the size of auger bits determined? Therefore, in all likelihood, the holes produced by ship head auger bits come out smaller than the normal bit sizes. Since work piece materials cannot be predicted, nominal bit sizes are selected by the theoretical hole size by most manufacturers of auger bits.
How deep can an auger drill? – Related Questions
What is a Jennings bit?
Jennings bits have two spurs at the cutting end which score the surface of your workpiece – ensuring a clean hole. The large, open flute of the Jennings bit facilitates rapid and easy clearance of chips. The screw tip assists in drilling by pulling the bit through the wood.

What size auger do you use for a 4×4 post?
Post Holes- If you plan to secure your posts with cement or by tamping dirt, you will need spacing around the post to do so. For example: A 4×4 post (actual size 3.5″x3. 5″) has a maximum width of just over 5″ (diagonally). Therefore, the 4×4 post will likely fit into a hole drilled by a 6″ diameter auger.
What size auger is best for fence posts?
A 12-inch auger, best attached to a heavy machine, will create a hole large enough for a 6×6 or 4×6 post and plenty of concrete. Smaller augers, like 4- or 6-inch options, are appropriate for light-duty work (like mailboxes) as well as metal fence posts for chain-link fences.
How do I know if I have a 1/4 inch drill bit?

How Deep Can Power Augers Dig? Most augers dig about 3 ft. deep, but for deeper holes, ask for an extension rod (Photo 5), usually for no extra fee.
Are auger bits good?
Auger bits are more efficient at clearing waste material from a borehole than Forstner bits. However, Forstner bits boreholes more quickly and can cut flat-bottomed holes. Auger bits are unsuitable for this kind of hole due to their large guide screws.
What type of auger bit would be used for fast boring in rough work?
Auger Bits (7″) – Fast wood boring through up to three studs. Screw point tip pulls the bit through for faster boring action. Ship Auger Bits (17″) – Fast, deeper wood boring in large timbers, decks and telephone poles.
Why is my drill not making a hole?
The most common reason a drill won’t penetrate a wall at all is because the drill is spinning in the wrong direction. If the drill bit enters the wall and then hits resistance, the typical cause is a metal plate or masonry obstruction.
How do you keep wood from splitting when drilling?
When driving screws, drill a pilot hole to prevent the wood from splitting. Drilling a pilot hole allows the threads of the screws to cut into the walls of the hole rather than forcing the wood fibers apart. This creates a stronger connection. Plus, a pilot hole will help the screw to drive in straight.
Why does my drill wobble?
If you’ve had the drill awhile, try retightening the chuck. After a fair amount of use, the chuck can become loose, causing the drill bit to wobble during use. To tighten the chuck, remove the battery pack and select the middle “off” position of the rotation direction selector.

A unibit (often called a step drill bit) is a roughly conical bit with a stairstep profile. Due to its design, a single bit can be used for drilling a wide range of hole sizes. Some bits come to a point and are thus self-starting. The larger-size bits have blunt tips and are used for hole enlarging.
What kind of tool is auger bit?
Share. 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.
What tool is used for boring holes?
A hole may be drilled or bored; awls, gimlets, and augers also produce holes. An awl is the simplest hole maker, for, like a needle, it simply pushes material to one side without removing it. Drills, gimlets, and augers, however, have cutting edges that detach material to leave a hole.
