Magnum hydraulic hand held core drill range
Our Magnum hydraulic hand held core drill range provide unrivalled power for both wet & dry drilling applications. Despite their power there is little or no kick or snatch due to the in-built pressure / torque limiting valve.
The Magnum comes with a heavy duty metal case, Magnum side handle and a drill drive adaptor (1.1/4.IN.UNC-M to 1/2.IN.BSP-M)
We sold our first Magnum in 1990 and the basic design has not really changed to this day.
Proudly designed, developed and manufactured here at Xcalibre Coventry, England.
Benefits & Features

Fitting telecommunication ducts into existing manholes it is now mandatory that diamond drilling is used to cut the holes so that the structure of the manhole is not damaged (by using breakers as an example).
Electric drills are not acceptable due to the potential presence of explosive gases and the wet environment, air drills can be used, however a large towable air compressor is needed, the drills are normally underpowered and need in-line oilers and water filters, these are generally not maintained resulting in an unacceptably high level of breakdowns and poor inconsistent drilling performances.
However the magnum 5 (600 rpm@20l/min) for hard concrete and brick or the magnum 10 (1000 rpm@20l/min) for softer concrete and brick are ideal for this type of work. They can be powered by small portable petrol or diesel powered hydraulic power packs and provides a small portable set up suited to these works.
Using 65 mm ( 21/2") and the 107 mm (4") diamond core bits with 5 and 8 segments respectively very fast drilling speeds can be achieved.
Examples are a 107 mm (4") diameter hole 225 mm (9") deep in brick in less than 3 minutes or less than 15 minutes in hard reinforced concrete.
The magnum can be used to drill any angle to match the incoming duct and because of it's compact design works well in the cramped conditions found in these manholes.
There are a host of examples of the magnum being used underwater, the hydraulic power packs are parked on a barge or structure above the water and the hoses are dropped down to the under water drilling position.
The magnum has been used for example, to drill fixing holes on pier refurbishment and on oil extraction structures.
When drilling larger diameter holes under water it is advisable to mount the magnum on a drill stand bolted to the structure - divers find it difficult to apply pressure to a drill because of the effects of buoyancy and currents.
Despite being under water, water flushing is still required for the diamond drilling process to clear away the abraded material from the cutting face.
Inverted or upside down drilling on for example bridges or on ceiling beams normally presents a serious problem for diamond drilling. The cooling water tends to flow back down onto the drill damaging electric motors and providing a potential for electric shocks. Whilst various ways of controlling the water can be tried, none are completely effective.
The Magnum is completely unaffected by water and is thus the ideal drill to use in these situations. One of many examples is a specialist diamond drilling contractor who was required to drill 28 mm ( 1.1" ) holes upside down in a concrete beam for the installation of fixing bolts. The contractor used a Magnum 24 ( 2400 RPM ) powered from an 8 HP petrol driven hydraulic power pack, the hoses were fed through a window leaving the fumes and noise outside the building.
Drilling larger holes upside down is tiring and we recommend the use of a drill stand if large numbers of larger holes are to be drilled. The same Magnum can be used to drill the fixing hole for the drill stand and then mounted in the stand and the larger holes drilled.
Holes are often required in bridges for fixing down railings or just to take samples of the structure for laboratory testing. As an example a government civil engineering laboratory needed to know the thickness of certain critical parts of bridges in their region to enable them to calculate the bridge's load bearing capacity. The laboratory technicians used a Magnum 15 ( 1500 RPM ) powered by a hydraulically powered coring trailer which they had freely available and drilled 25 mm ( 1") diameter holes to 1 M ( 3 ft ) deep in reinforced concrete bridges to find the thickness of the structure whilst minimising any damage caused by the drilling.
Worldwide, our Magnum range is well-trusted and has been used in many different industry sectors for example:-
Construction & civil engineering, diamond cutting companies, tool hire companies, pipe manufacturers, diamond drillers, telecommunication installers, safety fencing installers, plumbers, mechanical and electrical installers, marine industry, laboratory test houses, building contractors, civil engineering contractors, aviation, motorway maintenance, and road the testing industry.
