This angle grinder adapter increases the speed of the log inoculation process 4x by allowing you to use our specialized mushroom drill bits on an angle grinder. (Angle grinders run at much higher RPMs than hand drills!)

• Standard adapter is for 5/8-11'' spindles (for most USA, Canada, and UK angle grinders).
• Adapters that fit M14x2.0 and M12x1.75 spindles are also available.
