The new standard for electric hand sawing in concrete
Since December 2008, Adamas has experienced the effects of the construction industry’s global downturn. But instead of sitting back and hoping for the best, Adamas has used the current situation as an opportunity for its R&D engineers to come up with something special to generate sales in these difficult times.
But first, some history is order
The head office of Adamas is located in The Netherlands where electric hand sawing has been extremely popular since the early 1980s. Electric wood saws are usually adapted for wet cutting in concrete with Ø300 or Ø350mm diamond saw blades, and used for small alterations and renovation jobs.
As machines became more powerful in the last 10 years, contractors modified them to cut with Ø500mm saw blades up to a depth of 20cm in concrete and brickwork. This situation was regarded as unsafe and therefore forbidden by health & safety organisations. Contractors using these machines were heavily fined. Recent years have seen increasing demand for handheld electric saws for cutting jobs up to 20cm, but no supplier had the right product. Although electric wall saws are capable of cutting up to 20 cm deep, they are regarded as too big and heavy for these small jobs. Adamas sales representatives in the Netherlands and Belgium recognized this lingering market demand and used it to launch the R&D project. Nine months of thinking, drawing and fine tuning led to an innovated prototype named the “Eazy Saw.”
Easy sawing
The Eazy Saw consists of a 2200 Watt, 230 V electric drive motor protected against overload by a thermal relay and a slip glue. The aluminium gear case is integrated in the saw arm, which connects to a carriage with a patented hinge construction.
This hinge is the unique part of the Eazy Saw. It is robust and rigid, and guides the saw blade perfectly straight with minimum friction between wall and saw blade centre. That allows the relatively small motor to power concrete cuts of up to 21 cm in deep. The hinge also safeguards the operator when the sawblade become jammed.
The carriage guides the Eazy Saw over an aluminium track, which is bolted to the wall. Tracks are available in lengths of 1,3 and 2,3 meters, and have integrated double spirit levels and rubber bumpers. Spacer plates are available for uneven walls. The cutting process always starts with a Ø350mm saw blade, after wich a Ø450mm or Ø540mm saw blade could be mounted. Along with minimizing the physical load on the operator, the hinge permits plunge cuts in steps of up to 5 cm.
Cooling water for the saw blade runs through the gear case, and is efficiently distributed via the saw shaft to minimize consumption. An ergonomic rubber grip and a spray control cover on the blade guard prevent excessive sprays of water onto the wall, floor and operator, greatly reducing cleaning time.
Adamas officially introduced the Eazy Saw in early November at an exhibition for focussed diamond drilling and cutting contractors in The Netherlands. The response was very positive. The contractors claimed that the Eazy Saw fills the gap between hand held saws and mini wall saws. Practice tests show that the Eazy Saw can appled for a large variety of specific cutting jobs in concrete and brick work. The Eazy Saw will make its international debut at BAUMA 2010 in Hall A1-144.
