COR 5, 15
Overview
To reduce the risk of serious injury or death
to yourself or others, read the Safety
instructions section found on the previous
pages of this manual before operating the
machine.
Design and function
COR 5 and COR 15 are sturdy and reliable core drills
designed for working together with Atlas Copco
power packs. The core drills are small and flexible
machines with a high performance compared to the
weight.
The core drills are designed for water flushed
diamond drilling but can also be used for dry drilling
applications, which will not harm the seals. With
prolonged use in dry drilling applications, the
housing and shaft may become extremely warm. If
this occurs, remove the drill bit and run water
through the housing and shaft for one minute to
dissipate the built up heat.
The core drills can be used in drilling rigs. The
bearing housing is designed with a 60 mm cylindrical
surface that fits into industry standard drilling rig
mounting collars.
The directly driven hydraulic power design provides
consistent rotation and torque when drilling in
concrete, brickwork, or blocks for example. It also
makes underwater drilling possible. They are
designed for all kind of construction jobs. No other
use is permitted.
Never use the core drill as a rotation movement
supplier for other equipment.
To choose the correct insertion tool, see the spare
part list or the accessories catalogue.
The core drills are delivered with 2 m ⅜" tail-hoses
with ½" 'Flat-Face' quick-release couplings.
