Amazing

The kit to be used with angle grinders is nothing short of amazing and we were able to inoculate 8-9 Oak logs as opposed to 3..

Great pic, Sheila! We're so glad you're enjoying the experience.

Everything in one package. I bought the kit to add to my food supply. The drill bit was faster then putting duck tape on my drill bit. It went in just far enought. I have five logs under trees waiting to pin.

So exciting, Susan! So glad to hear you had a successful log inoculation!

This made short work of drilling the log I inoculated with Shiitake. Fingers crossed we'll start getting some stuff in a year or so.

Definitely worth the money.

A great bit for the hobby

I got the 12 mm-sized bit, which is excellent for using grain/sawdust spawn for logs and totems. The guard on the bit prevents you from drilling too deeply into the log, leaving consistent results for sowing the mycelium. This tool works great with the angle-grinder adapter and the sawdust loading tool. A must-have for anyone to make your log projects even easier to set up!

Thanks, Steven! We couldn’t do it without customers like you.

Game changer

Having this bit mounted to an angle grinder is a game changer, so much faster inoculation than a standard drill bit.

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 penetrate 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.
