New Dynamik Tools

from UNITECH UK

Hard Hitters?

Established companies with household brand names can still find it hard to launch a brand into a new market for lots of reasons. The locally established brands are much more likely to be purchased simply because they are more recognized and there is a dealer network. However, with recognition and branding comes a lot of responsibility to ensure that customers remain loyal, and new challengers will always be welcome provided the price and products are up to scratch. The joys of a competitive system!

The task that UNITECH UK has set itself is a challenging one – to successfully launch the German-made Dynamik brand of power tools into a crowded marketplace at a time of economic downturn. From a standing start, the tools have to prove themselves worthy of the competition and the distributors have not only to ensure stocks of the range, but also deal with any enquiries, service issues and all the rest. So, bearing all this in mind I set to unpacking the Dynamik DKH 45E-D Combi Hammer machine.
Just lugging the case from the car to the workshop I realized that this is no lightweight tool. Weighing in at nearly 6Kgs I was expecting a very capable machine. The case is blow-moulded plastic with custom fitted spaces for the drill (with auxiliary handle fitted) the long 4 metre cable, a tube of lube and a substantial space for drill bits. With metal latches and a lockable loop handle, the case is definitely capable of protecting the tool on site and in the back of a van.
The design of the hammer/drill follows a fairly well established pattern with the motor housing in front of a large vertically arranged loop main handle. An alloy gear and hammer-action casing is at right angles to the motor and projects forward to hold the SDS Max chuck and auxiliary handle behind it. What is beyond doubt is that this hammer drill combi is meant for demanding jobs as it is just BIG in most ways. I examined the ABS casing as I always do, for gaps and rough bits, but it was very well moulded and well screwed together. The rear loop handle made my hand seem small, and the red on/off trigger is a full 75mm long so it can easily accommodate gloved hands that will usually be necessary and recommended. The loop handle has some rubber overmould on the back of it to aid grip and there is a flexible joint between the loop and the top of the gear casing to absorb some of the inevitable vibration that occurs in a hammer drill.
The only other switchgear is a circular switch below the gearcase at the front. This switch allows the user to set either hammer mode or drill and hammer mode. In hammer mode alone the combi can be used as a demolition hammer with a spade bit to get between layers of mortar for example. It is pretty easy to set the spade bit to the right way up because there are sixteen positions in which it can be set.
I am always slightly dazzled by the size and complexity of SDS chucks, and this one is equally impressive. However, it is pretty easy to use as the large plastic outer sleeve is easy to move back when mounting the SDS Max bits into the machine. It usually takes a bit of jiggling of the bit to ensure that it is mounted into the correct grooves, but this chuck makes it easier than many.
With a powerful1100w motor, the Dynamik Combi Hammer is specified to drill up to 45mm diameter in concrete and will take up to a 125mm core drill in brick. As anyone who has ever done any core drilling will tell you, anything over 50mm diameter is hard work not only for the drill but for the operator too because the torque loads and vibration on the arms can be considerable. Not to mention the dust and noise – the full range of protective gear is an absolute necessity. In order to help counteract the torque effects of drilling and hammering, the front auxiliary handle is a full 260mm long. This can be adjusted to suit the user by simply unscrewing the handle, moving it and then tightening again. Left-handed users can unscrew the whole handle and swop it over to suit by removing the screwbolt. There is also a simple depth gauge rod that fits through a hexagonal hole in the handle and is secured by screwing the handle tight.
To be honest, for most core drilling and demolition jobs, what users want is a big, heavy and capable machine. Heavy machines can usually absorb some of the shock of the work by inertia alone, and you want a machine that will be heavy enough to follow the intended line of the hole you are drilling.
In all of the above, the Dynamik does not disappoint. It is big, heavy and clearly capable. The biggest SDS Max bit I have is only 20mm in diameter, but I had no difficulty drilling holes in concrete and stone. I did try a bit of chiseling on a flat piece of concrete and again the weight and power of the machine ensured that I could break and chisel it efficiently.
Some of the internal, and therefore less obvious, features of the machine are that has a safety clutch to protect the operator against drill jams, an automatic cut-off when the carbon brushes get worn out, and a variable electronic speed system via the trigger. When I used it, I was very happy with the noise and vibration levels from the motor – it is quite a refined machine to use despite the non-refined tasks that it is asked to perform.
Good machines cost money and this Dynamik DKH 45E-D has an asking price of £746.40 inc VAT. For that you get an initial 12-month warranty on parts and labour. After that, a lifetime labour-only warranty applies, with the purchaser only having to pay for parts. What this warranty proves is that Dynamik has confidence in its products. Potential purchasers should be reassured by this confident warranty – and it should help Dynamik with a successful launch on the UK market.
