Jackhammer (Electric Breaker) Rental in Bangkok: Complete Guide to Sizes, Specs, Pricing and Safe Use

A jackhammer, often called an electric breaker, is a power tool for breaking and chipping concrete, plaster, tile, and other hard surfaces. It works by delivering repeated impacts through a chisel bit to knock the material apart. It suits demolition and surface-opening work that is too slow or too hard to do by hand.

The most common confusion is between a breaker and a rotary hammer. They look similar but work differently. A breaker delivers impact only; the bit does not rotate, and it is used for breaking and chipping. A rotary hammer rotates and hammers together, and is designed to drill holes for anchors or conduit. Using a breaker to drill gives a poor, slow hole, and using a rotary hammer to break thick slab is slow and overloads the tool.

Work that suits a breaker includes removing concrete floors, chipping old plaster off walls, removing floor and wall tile, opening chases for pipe in thick walls, breaking small footings, and general demolition. The thicker and harder the material, the more you gain by using a breaker instead of manual labour.

If your main job is drilling holes for anchors, wiring, or conduit, look at the rotary hammer category instead. But for breaking, demolition, or surface chipping, a breaker is the right tool. See all models and rates on the tools and pricing page, or call and describe the job so the team can advise before you decide.

AR Rental Tools offers two breakers: the large breaker and the small breaker. Importantly, both rent for the same price and differ only in power, impact energy, and weight, so you can choose purely by the job without worrying that the larger one costs more.

The large breaker weighs about 16-20 kg with impact energy in the 40-50 J class. It suits heavy work that must chip through thick concrete, such as breaking a car-park slab, removing footings, breaking small beams, or removing reinforced concrete floors. The extra weight helps drive the impact fully into the material.

The small breaker weighs about 10-14 kg with impact energy of 20-35 J. It suits light-to-medium chipping such as stripping plaster, removing tile, opening wall chases, or work in confined spaces and overhead work where you hold the tool up. Being lighter, it tires the hands more slowly and is easier to control in tight spots.

The simple rule: the thicker the material and the longer the continuous breaking, the more you want the large model; for surface chipping, detail work, overhead work, or cramped areas, choose the small one because it is easier to lift and control. Since the price is the same, matching the tool to the job is what makes the work fastest and safest.

Both AR breakers run on 220V electric power and work straight from a mains outlet if the site has power, so a generator is not always needed. The upside is no engine fumes or noise, making them easier to use indoors than fuel-powered machines.

Check the site power before use. The large breaker draws around 1.6-2.0 kW and the small one around 1.0-1.4 kW, which is high. If the site outlet or breaker is too small, or you use a long, thin extension lead, you may get voltage drop or a tripped breaker mid-job. Use a correctly rated cable from a supply point that can carry the load.

If the site is open ground or has no power, budget for a generator too, and choose a size that covers the breaker's start-up surge, which is higher than normal running draw. Tell the team which breaker you will use and they can recommend a suitable generator size.

Bits matter too. Chisel tips come in a pointed type for concentrated point breaking and a flat type for stripping surfaces or removing tile over a wider area. Tell the team the job when booking so they include the right bits from the start and you avoid a return trip.

Rates referenced from the AR Rental Tools website at publication. Both the large and small breakers rent for the same 500 THB per day or 3,000 THB per week. This covers the machine with a standard bit and does not include site delivery if any, so always call to confirm the net price before starting.

Here is a simple example. A job removing a concrete slab at the front of a house, expected to take 3 days at the daily rate of 500 THB, works out to about 500 times 3, which is 1,500 THB before any delivery cost. This lets you set a rough budget before you even call.

For multi-day jobs, always compare the weekly rate, because once you use it beyond about 6 days the weekly rate of 3,000 THB is better than the daily rate. Seven days at the daily rate would be 3,500 THB versus 3,000 THB weekly. If you know the job is long, ask about the weekly rate when booking.

To compare the breaker against other categories in the same job, such as a concrete saw or plate compactor, see the tools and pricing page to plan the whole budget in one pass.

A breaker produces loud noise, dust, and strong vibration, so the operator should wear full protection: safety glasses, ear plugs or muffs, a dust mask, anti-vibration gloves, and safety boots. Dust from breaking concrete contains silica that is harmful to the lungs, so a mask and water to suppress dust both help a lot.

The correct technique is to let the weight of the tool press into the material rather than forcing it down. Hold it firmly with both hands, stand in a balanced position, and rest your hands periodically, because holding a vibrating tool continuously risks hand-arm vibration. Breaking up the work into rest intervals reduces both fatigue and this risk.

Electrical safety needs extra care. Check the cable and plug for damage before use, do not work in wet conditions or standing water, connect through an earthed outlet or a residual-current device, and switch off before changing the chisel bit. Never carry the tool by its cable.

Before you start breaking, make sure the area to be chipped has no water pipe, electrical cable, or important reinforcing bar embedded in it, to avoid damage or danger, and cordon off the area below or around to keep flying concrete off other people. If working at height, secure yourself and watch for losing balance from the tool's recoil.

AR Rental Tools has branches in Bang Kho Laem and Bang Khen. You can pick up at the branch or have it delivered to the site across Bangkok and nearby provinces. Delivery cost and truck slot depend on distance and the number of machines, and the team replies within about 30 minutes during business hours.

Booking takes only a few steps. Call 089-690-9876 or message LINE @ar.tools, say whether you want the large or small breaker, briefly describe the job, and give your start and return dates. The team then confirms the price, delivery cost, and truck slot before setting a pickup or delivery day.

On collection, check the cable, plug, and chisel bits for condition and completeness, and run the tool briefly before signing. If the machine has a problem or the accessories are incomplete, tell the team immediately so it can be swapped before you start, with no time lost on site.

For urgent same-day jobs, calling the team directly is faster than a long message, and if you give the project name or the district of the site, the team can dispatch a truck from the nearest branch to arrive on time.

The first common mistake is choosing the wrong tool type, using a breaker to drill anchor holes, or a rotary hammer to break thick slab, which makes work slow and loads the tool the wrong way. Avoid it by being clear whether the job is breaking or drilling; if unsure, let the team help you choose when you enquire.

Another is misjudging the site power. A breaker draws a lot, so if the outlet or extension lead is too small you will hit voltage drop or repeated breaker trips. Prepare a correctly rated cable, or budget for a generator if the site power is insufficient, so you do not have to stop mid-job.

A health-related mistake is using the tool continuously without breaks, which tires the operator, risks vibration-related hand numbness, and overheats the machine. Taking rest intervals and rotating operators extends the working life of both people and machine.

In short: choose the model to match the job, prepare enough power, wear full protection, and check the area before breaking every time. See details and rates for both breakers on the tools page or start from the home page to view other categories, then call to confirm the price and slot before the start date.
