Special Japanese drill bit Suitable for Inoculating Mushroom Spawn on sawdust

Directly from Japan, known as the initiator of shiitake cultivation on logs.

A special dowel punch is designed to easily create holes in logs. The advantage is that it quickly drills and cleans the hole effectively, eliminating the need for repeated cleaning. There is no need to worry about drilling depth as it has a built-in stopper.

Suitable for rotations up to 10,000 rpm.

The size is adapted for the mushroom planting tool.
