Convert your angle grinder into a high speed drill to make drilling holes into logs fast and easy.
Thread adapter onto your angle grinder (thread 5/8″-11tpi), then insert our specialized high speed auger drill bit. Choose an 8.5mm drill bit to make holes the perfect size and depth for inserting mushroom plug spawn. For sawdust spawn with a special inoculation tool, choose our 12mm drill bit. Both bits have a built-in depth stop so you can drill the holes to the right depth with ease.
