Alternative to Auger for Drilling 1.25" Hole in Live Tree?

[APD]

That video is impressive!

Where do those bits come from?

Any mushroom supply company, amazon, ebay.

would cooling with water work ? with a twist drill bit with holes at the cutting point for the water to cool and help push the chips out

This is an aussie Hollow Hog used for carving bird and animal hollows in trees. Angle grinder with round positive rake button carbide roughing inserts and a vacuum port. This makes short work of Australian hardwood gum trees. 1-1/2" x 6 into maple would take a few seconds.

they are Japanese Star-M and specifically for shitake inoculation. PRECISION TOOLS BY STAR-M CORPORATION

QT digger[My "Point" was who would drill into, and then inject acid into a "Living Tree" ?]

For to fill the tree with acid, let it grow a couple more years full of acid till all the nails and fence wire has been dissolved so you can run it through the saw with no broken teeth.

That should be the process till China comes up with a metal-eating wood bore bug.

Plus if we got rid of all the trees then firewood burning would not cause any global warming.

What’s wrong with an auger bit?

If it’s the screw point, there are augers available with a simple triangular point - so they are not self-feeding.

I doubt you’ll find anything that will clear chips as well as an auger bit.

We just used a conventional jobber drill bit for tapping maple trees.
We tapped the whole town of Nashville Michigan for a Boy Scout fundraiser.
Think the hole was about 3/8.

So they are pine trees. Mostly slash pine.

The purpose of the acid is to help the tree generate and release sap into a catch bag. The acid does not harm the tree. Once mature, the tree gets cut for lumber and replaced. Once the replacement trees reach 8 inch diameter, they will get the holes and sap will be harvested.

APD - thank you very much - not sure if it will work at 6 inch depth and 1 1/14" diameter, but that is the closest solution I had thought of. A pure auger running at 800 rpm requires a lot of torque. I am hoping for a solution where I can trade rpm for torque and this seems to do it quite well at least for oak.

This is a highly engineered solution and the drilling in my opinion has yet to be optimized. Hence my search for a better solution than a pure auger.

The more folks you talk to the smarter you get..........

You quoted me, like you had an answer, which you doo not.

My "Question" to YOU about "End or Side" was for the drill bit recommendation.
Qty (2) different ways of drilling.

Who would inject acid into a tree? Sounds like something Timothy Leary might have tried, sending the trees on a trip.

What do they do with the pine sap? Seems like all the holes would reduce the quality of the lumber? Or is it chipped for osb, reduced to fiber or some other process where the holes don't matter? What does the acid do, or are we getting into proprietary info?

Water jet, sand blaster? plunge in with chainsaw tip, I do not see any reason the hole has to be round or any particular diameter. No bigger then needed but large enough not to plug up too fast.
For rubber trees I thought they just slashed into the bark. I see now reason to go below the Xylem.

Second suggestion for forsner bit.

They can be custom cut to have a controlled cut format.

Example is with our radial arm saw.

Picked up a controlled cut blade, 10 ich with only 12 teeth.

Each had small gullet behind tooth and they barely were above the rest.

Would cut through a 2x10 as fast as you could pull it and cut was perfect.

Forming the correct cutting edge would restrict ho much bite the tool takes, adding a lip at the end to cut the fibers around the edge before the center removes the center.

Makes for very clean cut matched to the power available.

Add compressed air to blow out chips.

I thought that had all been replaced by petroleum distillates. I scrape all the pine sap gobs off my firewood into a 5 gallon bucket, mainly because its messy and its like throwing gasoline in the fire, sell it to a guy that makes aroma therapy stuff and incense, not much $ but it covers cost of fuel to cut the firewood.
