Is your bit sharp? You shouldn't have any problem using a speedbor bit other than the size of it making it go a little slow. With an extension you should be able to drill all the way through a pretty good size tree.

Yes the drill bit is sharp - this is a new bit, i purchased it specialy for the logs...
However, When I Am trying to make a hole with the 22mm speedbor the drill do its job very quick...
I tried the 32mm with lambers but the result was the same as with the logs...
That problem really weired to me...

Any idea?

I have had that problem on occasion, then found the drill was in reverse. 😉

I will give it a try myself and see what happens. What kind of wood are you trying to drill anyway?

I drilled about 5" deep into a white oak log using a cordless drill. It drilled pretty easily except the hole filled with shavings and would stop drilling. I had to remove the bit with it running pretty frequently to expel the shavings. If I were to go deeper with it I would probably blow air into the hole from time to time to remove the shavings.

I'm assuming that "Speed Bore" is a flat spade bit.

I know that this may sound stupid but try boring in reverse. I'm envisioning how the bits are made and thinking, "This side of the wheel is worn out, I'll just use the other side and keep my numbers up."

I note that these bits are like an augur but with triple cutters. I would have used a circular hole cutting bit for this diameter, but can appreciate that the speedbor should be faster and drill deeper. Perhaps start with a hole cutter, the bits are cheap, then continue with the speedbor.

Which type of Speedbor?

Auger:



Spade:


Speedbor by Irwin, comes in 2 types, auger or spade bits:
https://www.zoro.com/irwin-speedbor-...hoCLe4QAvD_BwE


The auger type will draw itself right into the wood.

The spade type will require considerable pressure to feed into the wood, especially on end grain. In fact it may not work at all on end grain and you'll need an auger type.

The auger is what he has. He's either not getting the screw in to take or the drill lacks the power to turn it.

The spade bit is what I used when I drilled into white oak.

Steve is right.
I do using an auger drill bit, yet no success has achieved with the 32mm diam.
I tried to use a smaller one (22mm) with the same power tools and the drill did its job...
However I Am still need a bigger hole so 32mm drill is required for this job but I cant make it work...
Anybody here succeded to make a hole with this auger size?

By the way I tried it on lambers and on oak logs too.... The same result...

It's probably the screw on the end of the auger giving you the trouble. You probably need to put more pressure behind the bit to make it work. The screw is probably resisting penetrating into the wood.

Actually yes. Clean the threads on the tip of the auger.

It might be easier to purchase a 32mm spade bit. They are cheap and will work.

32 mm equals 1.25 inches ....

Why not use a Forstner bit like this:

or this:

Just apply pressure, no auger tip to keep clean and cheap!!!!!

The 22 mm Speedbor auger works and the 32 mm Speedbor auger does not work. The problem is the drillers, the 32 mm Speedbor auger, or the log.

You tried multiple drillers with the same result. Unless all of your drillers are underpowered for this job, I would focus on the 32 mm Speedbor auger and the log.

Try comparing the 22 mm and 32 mm Speedbor augers on other woods. If the 32 mm Speedbor auger works well, then the problem might be the log itself, although it is hard to explain why you can drill it with the 22 mm Speedbor auger.

At that point, I would take the 32 mm Speedbor auger back to the source, or contact Irwin directly. Explain what happened. Tell them that the 22 mm Speedbor auger works well and list the troubleshooting steps you took. Ask for their recommendations. I would also ask for a replacement 32 mm Speedbor auger.

Consider other types of drill bits. I prefer Forstner bits, but would recommend trying a spade bit first, because they are inexpensive.

Are you drilling into the end or side of the log?

That would make a huge difference.

Drilling into the end yes.
I thought also That maybe the drillers doesnt suppling enough torque, or maybe the chunk is wick.. So I tried bosch 650watt power drill with sds chuck and used also an adapter for the speedbor.. Same result... No penetration... Is it enough power??

When I Am looking at the tip ended tharead it looks clean and with good shape... I used also forstner... Same result... Spade bit I didnt tried but I will....
