Drill Bits for Wood
Auger drill bits are bits used to drill holes into wood. They are commonly used for boring holes into bulkheads and general timber applications. These drill bits come with a spiral drill bit head which, when drilling, is designed to pull the bit into the wood so you do not have to apply excessive pressure.
Today we wanted to show you how an auger drill bit works. Most of these drill bits have a long stem on the end which attaches to the drill chuck. Then the
tip of the bit can start “biting” into the wood and pulling the rest of the bit into it. Before beginning your drilling application, you may want to put a piece of painters tape over the hole you plan on drilling into. Auger bits may chip the wood they are drilling into resulting in an unclean look. Painters tape should deter this from happening.
Auger bits are also designed to be run very slowly and with minimal pressure. Remember, the tip of an auger bit will help to pull it into the wood so you don’t need to apply a massive amount of pressure. We recommend about 600 rpm when drilling.
What About Nails?
Auger bits are incredibly durable and have the strength and cutting power to drill through nails and screws. It is important to maintain a slow speed and let the bit do the work. Once through the nail just continue on and finish the hole you are drilling.
What are the advantages of using an auger bit?
- Auger bits have the capability
- Drilling deep.
- Drilling neat uniform holes.
- Prevent the clogging of boreholes
- Auger bits allow for efficient clearing of wood shavings as a result of their wide and deep flighting.

Bob: Welcome back to Albany County Fasteners – Fasteners 101. I’m Bob and today I’m going to demonstrate the use of an auger bit.
So I have here an auger bit. This is a 5/8″ auger bit. 8 inches long overall. The stem part here which is pretty typical on all ship auger bits (which is what they’re really called here – Ship auger bits).
This part here is about 3 inches and its typical through all sizes. The lengths these come in anywhere from 8 inches to 18 inches long. I think there’s a 12 inch, maybe there’s a 10 inch, but you know you’ll have to decide based upon what you’re doing.
Also, auger bits they have this little screw in the front here. It is to pull the auger bit forward as it drills. These auger bits also will break or cut nails as they go through.
These are very cool bits. Used on ships and many other different applications but I’m going to demonstrate this now on drilling this auger bit into my sample piece of wood here. This is only for demonstration. Also, you should know that you should not run and auger bits more than 600 rpm.
So, slow as you go. It just draws itself right in.
Now it did splinter in the front here a little bit. If you don’t want it to splinter like this you take a piece of tape, blue tape or painters tape, and you put that on the front before you drill and that’ll prevent this from splintering the front face of the wood.
So I want to demonstrate to you an auger bit going through-they say that they can go right through nails, which I know they can, but I have a deck screw here that’s right in the top going down and I want to demonstrate to you an auger bit cutting its way through a deck screw. This would be a stainless steel screw. Let’s give it a shot and see what happens.
I’m up against it right now. Right through. Coming through the other side. Look at that.
So there was some resistance there but it cut through the deck screw. I think that was a number 10 deck screw, number 10 wire. So that would be equal to a like a Ten penny nail or a duplex nail. No problem. Right through with that baby.
Thanks for watching.
