For use with | Log drill bits |
This angle grinder adapter increases the speed of the log inoculation process 4x by allowing you to use our specialized mushroom drill bits on an angle grinder. (Angle grinders run at much higher RPMs than hand drills!)
- Standard adapter is for 5/8-11'' spindles (for most USA, Canada, and UK angle grinders).
- Adapters that fit M14 x 2.0 and M12 x 1.75 spindles are also available.

Making the world of mushrooms accessible to all
North Spore was launched in 2014 by a mycologist, an organic farmer, and a photojournalist -- three college friends brought together through their shared love of the mycological world.
What began as a simple love for mushroom foraging and cultivation quickly developed into an obsession with all things fungi. From there, an urban mushroom farm was born, as was the desire to spread the spore to the masses.

Total game changer
With another person to rotate the log, it would only take about 45 seconds to drill all the holes for one log. If you are doing more than a few logs, get the adapter and an angle grinder, it is worth every penny.
