Drill Fast, Consistent Holes for Plug or Sawdust Spawn

Make mushroom log inoculation faster and more consistent with our soft steel hex-shaft screw-tip drill bit with built-in depth stop.

Designed specifically for drilling mushroom cultivation logs and stumps, the screw tip helps pull the bit into the wood while the built-in stop creates a consistent hole depth every time. That means less guessing and much faster work when you're inoculating multiple logs.

Unlike bits designed for angle grinders or specialty quick-connect systems, this bit is made to work with an ordinary drill with a standard chuck.

🍄 Choose the Right Size

8.5 mm – For Plug Spawn
Choose the 8.5 mm bit when inoculating logs with our wooden plug spawn.

12 mm – For Sawdust Spawn
Choose the 12 mm bit when drilling holes that will be filled with sawdust spawn using a sawdust inoculation tool or plunger.

🌳 Designed for Mushroom Log Cultivation

This bit is ideal for inoculating hardwood logs and stumps with log-growing mushroom species such as:

  • Shiitake
  • Oyster
  • Lion's Mane
  • Reishi
  • Turkey Tail
  • Maitake
  • Other log-grown mushroom species

🔩 Built-In Depth Stop

The integrated stop prevents you from drilling too deeply and helps produce uniform inoculation holes throughout your log.

Consistent holes make inoculation faster and ensure your plug or sawdust spawn fits properly.

🛠️ Works with an Ordinary Drill

No angle grinder or specialty drilling equipment is required.

The hexagonal shaft fits standard drill chucks, making this a great option for home growers who already own a regular electric or cordless drill.

♻️ Sharpen and Reuse

Made from soft steel, the bit can be resharpened with a chainsaw file, allowing it to be maintained and reused for years.

Each bit also comes with a protective storage tube so it doesn't disappear into the mysterious black hole otherwise known as the toolbox. 😂
