Oil Flow and Pressure
Your new Rhino®core drill is designed for a certain oil flow, working pressure and maximum
pressure. A too high oil flow and/or a too high pressure results in overload of the core drill,
meaning that the lifetime of your new Rhino®tool will not be as expected, and that you incur
higher service and repair costs will be higher
It is important to check that the core drill is not supplied with an oil flow beyond its design
capacity, that the working pressure is correct and that the maximum allowed pressure is not
exceeded.
On page 7 you will find the technical data, and on page 10 there is a guide to connection to
hydraulic power sources and how to ensure that the core drill is not overloaded.
Useful Information Regarding the Use of Core Drill
The Rhino®core drill is a small and compact tool with a high performance. There is no other
core drill on the market with a higher performance in relation to size.
It is the perfect tool for drilling jobs in all kinds of concrete, brick wall, asphalt etc.
The core drill can be mounted in a rig, but the great advantage of this tool is that all drilling
jobs can be done by hand. This is due to an automatic clutch, which makes the core drill stop
immediately if the core bit jams.
The core drill has two handles, and with a 360° infinitely variable adjustment of the front
handle, optimum operator comfort is achieved.
The core drill can drill holes from 1.97” to 13.78” (50 mm to 350 mm). Drilling jobs beyond
7.87” (200 mm) are for experienced users only.
The rotary speed is variable by means of the lever, which facilitates the drilling start.
As handheld drilling is possible for all jobs, the operator saves a lot of time as he does not have
to mount a drilling rig prior to operation. For rig drilling, the Rhino®core drill can be mounted
in the most common drilling rigs with a diameter of 2.36” (60 mm).
The core drill is unaffected by water and can be operated in all non-hazardous environments –
also underwater drilling. This means that there is no shock hazard in excavations etc., as is the
case with electric core drills.
The core drill can also be connected to excavators and other machines. We recommend the use
of a Rhino®oil flow divider to protect the core drill against a high oil supply, high pressure and
backwards rotation. Please refer to page 10.
