Does Exactly What It Says On The Blade!
Marcrist International have developed a revolutionary diamond blade that cuts all materials found on site, (concrete, general building materials, natural stone and even steel) - a four in one blade.
Diamond Core Drills Cut Costs
Marcrist's DCU700, like all its other diamond core drills, provides a quick and easy method of cutting through a wide range of materials.
Combined with the purpose-made DDM2 diamond drilling machine costing just GBP150 - a fraction of the cost of other drills on the market - diamond drilling is expected to become an affordable option for virtually every builder, plumber and electrician.
The current cost of employing a diamond drill contractor, or hiring the equipment, means that the vast majority of large bore holes for domestic and commercial services are formed by stitch drilling or by creating an opening with hammer and chisel.
This is time-consuming, and usually requires considerable effort to 'make good' after the opening is created.

New Bahco Lopper Gives More Power To Your Elbow
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.
In contrast, Marcrist's new diamond drilling system allows perfectly smooth holes of up to 200 mm (8 inches) to be created in minutes, at an unprecedented low cost.
To illustrate the efficiency savings, Marcrist has timed the processes required to create a 127 mm hole in a 200 mm thick reinforced concrete wall.
Diamond drilling performed the task cleanly in just 6 minutes, saving a total of 46 minutes compared with using a hammer and chisel.
The cost of diamond-drilling such a hole is counted in pennies, thanks to Marcrist's unique pricing strategy for this product.
"We've developed a product and pricing strategy that puts diamond drilling within reach of every jobbing tradesmen," says Mario Halbeisen, Managing Director of Marcrist.
"Payback for the new system is almost instant, and many tradesmen could save thousands of pounds over a year".
Our designed-for-purpose diamond drill costs around 5 pence a day to run, and the patented diamond tip on our new drill cores is so resilient that large-bore holes can be dry-drilled for as little as 10 pence".
"The alternative is up to an hour's labour per hole, or tens of pounds to hire an existing generation of diamond drilling equipment - even more, to bring in a contractor".
Marcrist, headquartered in the UK, is one of Europe's largest producers of diamond tools.
The first part of this diamond drilling innovation is its new CCU range of diamond core bits for professional use.
These cores, for holes from 22 to 200 mm diameters, feature a patent-pending cutting tip with a bond of natural and artificial diamonds that will perform at very high temperatures.
This performance attribute allows the tips to drill virtually every building material without water coolant, allowing users to create holes without preparation, and virtually no mess.
Standard materials such as concrete, breeze blocks, bricks, engineering bricks, and stone, can all be drilled dry.
The only materials the drill will not handle without coolant are those based on very heavily reinforced concrete.
The second part of the package is the high-torque DDM2 drill, developed and manufactured specially for Marcrist.
This 1500 W tool features two-speed operation to provide the optimum cutting speeds for the diameter of hole being drilled, an integral clutch, a built in RCD protector and an oil-filled long-life gearbox.
There is also an integral water swivel to allow users to tackle more demanding drilling jobs such as creating service openings or anchor points in reinforced and hard concrete on civil engineering projects, using a wet- grade drill core.
Marcrist's professional diamond drill cores offer typical lifetimes of between 200 and 500 holes.
Prices start at GBP68 (88 euros) for a 32 mm diameter core.
Marcrist is also offering a lower cost range for frequent users.
In addition to changing the economics of diamond drilling, Marcrist has incorporated a number of useful features to improve ergonomics.
One innovation is a concertina-like sleeve which slips-over the drill core and collects the dust as drilling takes place - eliminating the need for a vacuum cleaner.
Another key advance is a simple means of removing the 'plug' of building material from the core following drilling.
Many users currently claw this out with a screwdriver, or bang it with a hammer to shake it loose - potentially causing damage.
Marcrist has devised an elegant core extraction system that it believes is a first in this field.
A weighted pendulum can be simply hooked on and tapped - forcing the plug to slide out.
Halbeisen adds: "There are around a quarter of a million jobbing builders, plumbers and electricians in the UK alone who could benefit from this innovation".
"We expect to see a large proportion of these professionals owning their own diamond drill within two to three years.".
