Boring and milling machine for paved slabs
A machine for boring holes into a slab includes a plurality of milling bits mounted on a distal end of a rotatable carrier and a coring bit slidably connected to the carrier such that the coring bit rotates with the rotating carrier and is slidable axially relative to the carrier. The coring bit cuts a relatively smooth bore into the solid medium whereas the milling bits create a bore with a relatively rough finish. An actuator engages the coring bit to adjust the depth of cut of the coring bit relative to the milling assembly depending on the desired finish of the hole to be bored. An undercut assembly is mounted on the carrier and selectively operable to form an undercut in the slab at the bottom of the hole so that a cured patch of material poured into the hole is restrained from working loose from the hole.
