Drill holes to the right depth with ease using our 8.5mm high speed auger bit with built-in depth stop. Drill hole into freshly cut log, insert mushroom plug spawn, and cover with melted wax.
Use with regular or high speed drill, or purchase with our specialized anger grinder adapter to convert an angle grinder to a high speed drill. Auger bits enable faster drilling by expelling wood chips from the hole more efficiently. Round shank.
