Mushroom log inoculation drill bit
Works much quicker than drill bits! Thanks

Where have you been all my life?
I wish I had discovered this 4 years ago when I started drilling logs. It was a total game changer. It stops at the perfect depth every time AND it empties the hole of the sawdust. The plugs fit perfectly.

Well worth cost!
I have other bits and bit stops for plug insertion, but this one (even after 2100 plugs) clears the holes perfect with no efforts!

This bit is ready to work hard!!
This drill bit is ready for a full day of innoculating. It’s super sharp and works really well.

Drill bit
The bits performance was good Stade sharp over 2000 holes. The only change I would make is to make the collar deeper and wider for logs with bigger bark.


Slid right in
My Mushroom Log Inoculation Bit entered the wood with ease. All I had to do is place the tip on the wood and push. The twirling action of the Mushroom Log Inoculation Bit helped it ********* the wood hard and fast. I knew I hit the perfect depth and penetrated the log again and again. After pulling out my Mushroom Log Inoculation Bit from the final hole, it was time for North Spore’s hardwood mycelium covered dowels to fill the log’s empty holes. To my surprise, I could barely squeeze the dowel in because the Mushroom Log Inoculation Bit’s holes are not that big. I got my hammer because I knew if I was going to finish the job, more force was required. Again and again I hammered the dowels in. Every dowel was covered with white mycelium and once the mycelium gets into the log, it makes a mushroom. That’s how my Mushroom Log Inoculation Drill received a Five Star Rating! I was not compensated for this review, but if North Spore was cool they would send me one fruiting block of every type of mushroom they have. Thank you.

Resistance is futile
Sublime

Quality drill bit
Worked great had no problems. the bit was a little pricey.

must own
If you're doing anything but a tiny log project, you need this bit and the angle grinder attachment. Save your wrist and tons of time and energy.

The right hand tool job
No more square holes for this guy, I'm going round from now on. I went online this morning not even knowing it was possible to make round holes in things. It's amazing how far we've come. Now I just need to figure out how to make holes in a up/down direction and not the other way.. oh wait they even sell an angle attachment. Neato!
