Marcrist's DCU700, like all its other diamond core drills, provides a quick and easy method of cutting through a wide range of materials.
Have You Given Diamonds A Spin? Are you still living in the dark ages where making a hole in the wall is a labour intensive operation? At the best of times making a hole normally involves a hammer and chisel and making a messy and untidy job But by investing in a small amount of equipment, you can use your standard 2kg hammer drill with a diamond core drill and go through anything, time and time again providing a clean hole, quickly and easily

Marcrist dry diamond cores revolution
Marcrist International has developed two unique styles of dry diamond cores that will revolutionise the way in which cores are seen in the future.
Marcrist International Ltd has pioneered the use of diamond cores for plumbers and builders for over twenty years now.
Based in Doncaster, Marcrist has a purpose built manufacturing plant designed to produce tens of thousands of diamond core drills per month for delivery all over Europe.
All this and yet, surprisingly, some people have not turned on to this cost effective and professional way of making a hole.

Bahco's new PG-20 Small Bypass Lopper is specifically designed for gardeners who find big loppers too heavy or unwieldy to use in a small garden, but need something with a stronger cut than secateurs.
From drilling through tiles to bricks, blocks and even natural stone and concrete, a diamond core will go through it all.
Not all diamond core systems are as versatile as the Marcrist one.
Whilst using just a drill and a diamond core will be adequate for most jobs Marcrist has also developed a systems solution to allow this set up to be even more versatile.
At the heart of the diamond drilling system is the Marcrist Combi unit.
This simple addition to your toolbox will enable you to drill dust free when attached to a vacuum cleaner, and by just attaching a water connection (also provided) you make the versatile tool capable of wet drilling even the hardest of materials such as granite and reinforced concrete.
The whole system has the advantage of using a pilot drill to ensure you don't go slipping around the wall and allows accurate placement of the holes.
Dry Diamond core drills are available in a multitude of sizes from as small as 22mm through to even 200mm if you have a drill to cope with it! The popular sizes are 38mm used for 11/4" waste and sleeved gas mains, 52mm for 11/2" and 2" waste and 11/2" solvent sleeve, 117mm for soil pipes, extractor fans and boiler flues and 127mm for black hole vents, larger boiler flues and a 152mm core can be used for soil elbow, oil burning boiler flues and gas fires.
All the cores can be fitted with an extension rod between the drill and core to enable you to drill through even the thickest walls.
Another important issue concerning making holes is the amount of noise that can permeate around the building.
This is particularly relevant when working in Museums, tourist areas hospitals and Nursing homes.
An example of this is a contract recently carried out at a Suffolk nursing home where the residents were spared the usual noise and vibration that accompanies construction work.
St Mary's nursing home is a substantial Victorian mansion house, built in 1885 in the conservation area of Old Felixstowe in Suffolk.
In the Second World War it was used by the Ministry of Defence, during which time a single-storey extension with a blast-proof roof of reinforced concrete was added at the rear of the building.
The building was converted into a nursing home in 1986.
St.
Mary's has recently been extended again, this time with the addition of a further 18 bedrooms, all with en-suite facilities.
The new extension was to be built around and above part of the old wartime extension with its blast-proof roof.
This presented an immediate problem since it involved drilling through 250mm high strength reinforced concrete to install soil pipes and central heating services, whilst at the same time keeping noise and vibration levels to an absolute minimum so as not to disturb the elderly residents of the home.
The company behind the project, J H R Wisbey Project Management Services said: "There was no way we could have used jackhammers to break through the concrete.
Apart from the necessity to make good the hole afterwards, which can take as long as making the hole itself, the noise would have reverberated around the nursing home and the residents would have had to be evacuated to the furthest wing.
"Wet drilling would have effected electrical connections to the fire alarms, nurse calls and lighting, all of which had to be maintained at all times, and the proximity of the walls ruled out using conventional rig-mounted drills." After consulting local builders merchant, the company was advised to try a diamond core drill from Marcrist and eventually settled on a 117mm DUC700 model.
A representative from J H R Wisbey, John Wisbey said: "The DCU700 was able to cut through the reinforced concrete and produced a neat hole which didn't need to be finished off.
From the operative's point of view, it was as quiet as using a vacuum cleaner, and even although we were drilling from above into a corridor, people in the adjacent bedrooms heard hardly any noise at all.
We were therefore able to carry out the work with minimal disruption to the residents and staff." The same system was also used for drilling horizontal holes through masonry walls, where the speed and efficiency of the operation surpassed all John's expectations.
"Going through masonry walls, the DCU700 was just brilliant, it went through easily and required minimum 'making good'.
"Diamond core drills have certainly advanced greatly during the past 20 years.
In the 1980's, wet drilling was the conventional method but with the DCU700 I have the option of doing both wet and dry drilling, depending on the requirements of the job.
In addition, I received an excellent service Marcrist.
I'm well impressed." Marcrist's DCU700, like all its other diamond core drills, provides a quick and easy method of cutting through a wide range of materials.
