These specialized drill bits are used to drill holes into logs prior to inoculation with mushroom spawn. In addition to speeding up the process, they also ensure that each hole is an identical size and depth.

Make sure you have the proper sized drill bit for your mushroom log project.

• 8.5mm drill bits - for plug spawn
• 12mm drill bits - for sawdust spawn
