Quick-change mounting system made for hole saws
Pferd offers a new mounting system for hole saw changeups. The quick-change system consists of two pieces: a drive arbor that mounts to the drill and adapters that mount to each saw. With the adapter attached, the hole saw can be attached to and removed from the arbor instantly with the press of a button. This system can be used with hole saw diameters between 0.5625 to 6 in.
The drive arbors and adapter sets are sold separately. The drive arbor features a 0.4375-in. hex shank and ships with a 0.25 in. pilot drill. Three-piece adapter sets are available in two thread pitches. Each set contains three identical adapters, allowing the user to have three different sized hole saws ready to go.
