This adapter vastly increases the speed of the log inoculation process by allowing you to use our specialized mushroom drill bits on an angle grinder. Angle grinders run at much higher RPMs than hand drills.
The 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.

This adapter transformed my angle grinder into a super-fast inoculation hole drilling machine. If you value your time at all, and you have a lot of logs to inoculate, then this widget is definitely worth the investment.
