Draper Tools has a huge and enviable range of products that is constantly being revised and uprated according to the needs of the market, so it was with no surprise at all that I took delivery of the 1600W 15Kg breaker (Stock no 83352) to review. I have tried out a few smaller breakers and hammers and have got on very well with them because I have always been able to use them on jobs where a bit of concrete needed breaking or a few bricks needed chopping out. More to the point – my back has not been strained by having to lift those much lighter tools. But the Draper 15Kg breaker took me to a new place – a really powerful tool meant for serious breaking of concrete and masonry – with a serious weight to it that is needed for doing such jobs. I had to ring round my friends to see if they had a job big enough to try it out on for a start.
Lots of small building firms need to use breakers, and I guess for many of them, the first call would be a hire shop to get an appropriate breaker for the job. However, with a typical internet price of around £150, this Draper 15Kg breaker is very affordable and stored in its plastic carry case, it won’t take up much space in the back of a van either. If my experience is anything to go by, the machine is capable of breaking concrete paving and floors as well as hard brick and stone up to a level that is more than enough for most small users. Workers on skyscrapers and major infrastructure products may need bigger breakers, but most builders would be happy with the performance of this one.
A quick check on the specs will show you what I mean. The breaker is a standard 230v machine with a weight of over 15Kg with a chisel fitted. The impact energy is a very decent 45 Joules at an impact rate of 2000r per minute. Chisel size is 29mm and with a sound power level of 105 dB(A) it is necessary to wear hearing protection during use. A breaker works by impacting on the concrete so workers should always be careful to protect hands from over exposure to vibration by limiting time spent using the machine.
I am a fan of plastic cases with enough room to accommodate all the odd bits and pieces associated with the tool inside. The plastic case with this tool has a big strong handle and latches and will easily hold the four-metre long heavy duty cord and the two extra chisels supplied (one pointed, one chisel end) as part of the kit. Nice touches are a plastic oil bottle and a spanner to do the simple maintenance required. A spare pair of carbon brushes is also included.
Construction of the body is mostly heavy duty metal that is needed for such a tool, and is well held together with no-nonsense hex screws. Firmly attached to the main body is the main handle that is a large robust plastic construction that slightly isolates the users’ hand from vibration. The yellow trigger is large and can be locked into “on” position via a button for continuous use. There is some grippy rubber on this handle too to aid handling.
The auxiliary handle is a robustly made square loop with a big ribbed and softish plastic handle to grip. This handle definitely reduces vibration transmitted to hands and the whole thing can be adjusted a full 360 degrees to suit users’ preferences.
Underneath the main motor housing is the oil reservoir with its transparent cap so that oil levels are easy to check. Using the spanner and oil bottle supplied with the kit, it is easy to fill the oil when needed.
Inserting the chisels is very easy too. After a light greasing of the tool shaft the locking bolt is pulled out and turned 180 degrees. The shaft of the tool can then be inserted and the locking bolt returned to its original position. The chisel will be free to run up and down the shaft as the impact mechanism does its job.
One of my mates did come up with a suitable test bed – demolishing some concrete steps and adjoining brickwork so I hotfooted over to try the breaker out. The machine uses a standard moulded 230v plug so there was no need for a transformer – a simple plug into the extension cord was all that was required for the machine to be ready. Health and Safety says gloves, boots, eye protection and ear protection are needed as a minimum and once I had started the job I knew why. The Draper breaker does what it says on the tin – it breaks concrete etc very efficiently. It helped me that the weight of the tool does the job for you as well as helping to keep the chisel where it is needed. My job was largely to keep the chisel tip in the place where it could be most efficiently employed in breaking up the concrete. By focusing on breaking up the concrete from the edges and then also exploiting cracks that developed as I worked, it took about half an hour to break most of what we needed. The brickwork was much easier because they were just ordinary clay stock bricks and didn’t stand much of a chance against the chisel end.
I am still very glad that I don’t have to use breakers very often because my aging muscles don’t like it, but I am convinced that breakers fall into the category of Very Useful Tools because they do a unique job which is probably more commonly needed than I know. Because it comes as a whole kit in a case, ready to use, and because of the price point, the Draper 15Kg Breaker is a good bit of equipment for builders to include in their tool collection.
