Mushroom drill bit made specially for mushroom log cultivation using sawdust spawn.
If you are inoculating a large number of logs, it can be more economical to purchase a few tools and use sawdust spawn (rather than plug spawn).
This drill bit with depth stop can be used with a regular or high speed drill, but the fastest way to drill holes into logs is by attaching the drill bit onto an angle grinder with this special adapter. Use an inoculation tool to easily insert sawdust spawn into the hole, then seal with melted wax.
Note: This bit may not fit angle grinder adapter tools from other suppliers and does not fit an “impact” driver. Angle grinder adapter sold separately. For plug spawn use a 8mm or 5/16″ drill bit.
