What it is
The complete arbor with pilot drill bit for hole saws Fervi 0712/700 is the supporting accessory that connects the hole saw to the drill, complete with a centring bit to start the hole accurately. It has a shank with a round Ø 6.35 mm arbor and a hexagonal Ø 11 mm arbor, for a firm hold in the chuck and good torque transmission during drilling. The reference article code is 0712/700.
The arbor, also called the mandrel, is the rod with a drill fitting that holds the hole saw. At the centre it carries the pilot bit that guides the hole and has a system, screw-type or quick-change, for locking the saw.
What it is for
Used for drilling wood and panels, for drilling steel, stainless steel and aluminium, on a pillar drill or with a hand-held drill and for running services through walls, floors and suspended ceilings.
How to use it
Choose the arbor suited to the diameter of the saw and its fitting, fix the saw, check that the pilot bit protrudes as needed and tighten the arbor in the drill chuck. Replace the pilot bit when it no longer centres properly and keep the arbor clean.
