Famag Quick-release pump shank with guide pin

Tungsten carbide-tipped universal hole saw with a steel body, cutting depth of 165 mm, capable of cutting through all types of wood and panel materials (including solid wood), MDF, aerated concrete, drywall, and plastics. With its long usable length, it is ideally suited for drilling through holes in solid wood for ventilation, drainage, and flue pipes. A pilot hole with a diameter of 10 mm must be pre-drilled for the guide pin. Thanks to the particularly clever PUMPSHANK®, the saw core can be easily removed, saving you a lot of time and hassle. Once the saw has engaged, the mandrel can be removed.
