Latest developments in handheld toolsPublished 7/3 at 16:37
The last 12 months have seen many new interesting handheld tools from a wide variety of companies being launched. Here are some of the most prominent developments now entering the market.
The Swedish company has released the K 535i, which is the latest addition to Husqvarna’s battery powered range. The K 535i battery powered cutter utilises many of the same features as its fuel and electric powered compatriots, while adding benefits such as low vibrations, low weight and user friendly ergonomics to the mix. It’s almost maintenance free and offers a low cost of ownership. The power to weight ratio of the K 535i especially makes it a useful addition to any landscape or hardscape contractor’s equipment range and as it doesn’t depend on power from the grid, it can be used whenever and wherever it’s needed. The slim design and weight (3.5kg) make the K 535i easy to lift, control and maneuvere, while the centred placement of the blade provides increased stability and control when compared to conventional angle grinders. The K 535i can be used for both wet and dry cutting, and allows for adding accessories to help facilitate dry cutting. The handles are specially developed to be comfortable, and increases control for extra safety while cutting.
Taiwan-based manufacturer AGP has launched a new 330mm ring R13 ring saw, which has a 3200W electric motor and a cutting depth of 220mm. The 3200W universal motor comes with electronic overload and thermal protection, and has a unique, single stage blade tensioning system that is according to AGP faster, easier and more accurate than traditional systems. Furthermore the R13 has a high stability guide roll design which keeps the sawing ring stable and central when the cut begins. An LED indicator shows the load conditions, with any change being able to be performed quickly, not requiring any disassembly of the cover.
As of 1 January, 2019 AGP has established a Germany subsidiary, AGP Germany GmbH, located in Bochum. AGP Germany GmbH specifically manufactures equipment for the diamond tool industry, with a comprehensive range of core drilling machines, diamond saws, ring saws, chain saws, grinding machines, core drilling stands and grinders, with other developments to follow. The new subsidiary with a staff of 20 is headed by managing director Stefan Klebowski, who has more than 25 years of experience in the industry. The German based operation will also service the requirements of neighbouring countries.
New and existing AGP products will be exhibited at hall EWE 06 at bauma 2019.
DeWalt has introduced a new power cutter, DCS690, with a new 54V battery. It is easy to use, of low weight, and designed to easily and quickly cut through many demanding materials, such as stone, concrete, asphalt, metal and steel. Maintenance requirements are minimised as there is no need to mix fuel, and there is no filter or spark plug that needs to be cleaned. With a simple push button start, and with the help of a built in overload indicator, the user can easily adjust the cutting speed and cutting power during cuts, which offers both increased safety and fewer abruptions. The machine is well protected against dust and water, and has a dust control system which feeds water at both sides of the blade to effectively protect against dust while working in concrete and stone. The DCS690 has a brushless motor and a speed of up to 6600rpm and a cutting depth of 83mm.
The new Ryobi 18V brushless reciprocating R18RS7 saw is ideal for demolition work with 40% more power and longer runtime than its other 18V reciprocating saws. It has a speed of 3200bpm and a length of stroke of 30mm. The electronics communicates with all Ryobi 18V lithium batteries, and when in use, the motor and the battery identify which effect is necessary. An anti-vibe handle helps absorb any vibrations, whilst the reciprocating saw also has a safety switch to prevent unintentional start as well as a tool free blade shaft, built in LED light and blade choice. Together with Ryobi’s One+ 5.0 Ah lithium battery, this reciprocating saw reaches up to 260 cuts of beams at 45mm x 90mm.
Baier has recently added to both its dry and wet dry coring ranges, with tools able to process all types of stone. Fitted with a vacuum cleaner, unique soft impact system and titanium core bit, the Baier dry coring machines can easily cut through concrete with rebar, granite and so forth. Baier supplies its BDB 825 with ø160mm diameter, and since April 2018, the two gear BDB 829 with a maximum diameter of ø250mm. In addition to its dry coring offering, Baier has a wide range of wet coring machines, starting at ø6mm up to ø550mm, all with 230V.
Liechtenstein based Hilti has introduced its latest generation of electric cutters, including the DCH 300-X, which benefits from wet cutting capabilities and accelerated cutting speed. The largest handheld electric cutters from Hilti can cut through 120mm of concrete, masonry walls or flooring, using a 305mm blade. Hence the DCH 300-X’s cutting depth is ideal for cutting or widening openings in all the most common concrete and masonry thicknesses. When it comes to cutting rebar, Hilti offers Equidist diamond blades that are subject to a precise manufacturing process where each diamond is arranged individually into a grid on the cutting surface. Due to this technology, the cutting time is reduced by 30%. The DCH 300-X includes a hose connector and dust hood with depth gauge straight out of the box, enabling users to start work straight away.
Hilti has also released the new DSH 600-X gas saw equipped with diamond tipped blades. Easy start technology eliminates the manual choke for more first pull starts, and reduces the risk of flooding. It can be used for cutting through materials such as concrete, masonry and steel, and also has the versatility, for example, to cut kerb stones and paving slabs to size. The DSH 600-X with top handle weighs 9.5kg, has a 60cc engine and is equipped with a 300mm blade that achieves a maximum cutting depth of 120mm. An optional DSH-P water pump accessory provides independence from water supplies during wet cutting. The DSH 600-X also comes with a cyclone air filtration system which uses centrifugal force to remove dust and debris from the engine air intake.
As an addition to the theme of handheld machines, Solga Diamant has developed a new line of dry-cutting diamond blades for handheld thermic machines. The blades do not require water supply and are developed for handheld jobs where wet cutting might not be a viable option.
