More efficient than a percussion drill, the drill pierces concrete and stone without worry, and can be turned into a chisel for small demolition work. But is he really enduring on drums?

Use a wireless hammer drill.

With the evolution of batteries, power tools have gained autonomy, maneuverability and power, like these six drill chisels. They find themselves more and more at home, despite still high prices.

Hole puncher: an effective strike with few strokes

To limit manufacturing costs, wireless perforators do not all turn into chisels. For this, the machines must be equipped with a battery of one good voltage and a good amperage and have a excellent strike force. The six devices tested here have this function.
The wireless drill has a electromechanical striking mechanism (or electropneumatic) identical to that of the wired models. It propels a hammer on the tail of the drill at a relatively slow rate of 3000 to 5000 cps / min, for 1000 to 1400 rpm max. This striking system is much more efficient and generates less vibration and noise than a percussion drill that operates at a frequency of 20,000 to 50,000 cps / min.
The strike force is expressed in Joules (J) and it is one of the main criteria of choice. The power of the perforators of our test ranges from 1.3 to 2.8 joules. The striking mechanism disengages to rotate the wood and metal. Screwing and unscrewing can also be envisaged. The rotation of the mandrel can be blocked to allow small chiselling, to take off the tiles for example or to puncture blocks, bricks, soft stones...

Batteries source of energy

The six selected machines are equipped with Li-ion battery (lithium-ion) 18 to 36 V and 1.3 to 5 Ah. The higher the voltage, the stronger the punch. The more amps, the greater the autonomy. It is thus possible to drill concrete with drills of diameter ranging from 16 (Ryobi) to 26 mm (Hitachi) and more than 70 holes of Ø 10 x 80 mm.

Perform settings on a chisel punch

Sliding ring system for changing impression tools.

On each mandrel, a sliding ring system facilitates the change of SDS + impression tools. On the Dewalt and Makita, the ring is particularly wide and flexible.

Adjust the depth gauge.

The depth gauge adjustment is simplified on the Bosch and the AEG. Just press a button on the auxiliary handle to unlock the gauge.
On others, it is done after loosening the auxiliary handle.

Slide the auxiliary handle around the piercing head.

On all machines, the auxiliary handle slide around the piercing head. On the Makita, pins can direct it in steps of 20°.

Rotate the adjustment knob to choose how to use the punch.

The perforators propose three settings: classic drilling, percussion and chiselling. A neutral point makes it possible to turn the mandrel to orient the chisel.
On AEG, Makita, Bosch and Dewalt, the knob is wide and easy to turn.

Adjustment button to choose how to use the punch.

On the Ryobi and the Hitachi, it's a bit small.

Use the direction reverser of a hammer drill.

In conventional drilling, it is also possible to to screw and unscrew.
Each machine is equipped with a inverter of meaning. It is particularly well located on the Dewalt.

Check the battery charge level

Check the charge level.

The batteries are equipped with charge level lights (except Hitachi). To check the level, you have to press a button that lights leds.
It is particularly wide and easy to handle on the AEG.

Remove the battery from its housing.

This is done without removing the battery from its housing, except on Bosch and Dewalt.

Switch on the battery on the charger.

All batteries can be easily tripped on their charger.
That of the Makita perforator is equipped with a cover that protects the contactors from dust and shocks.

Strengths and weaknesses of drill chisels in use

Chipping perforator equipped with a shock absorber system.

The machines (except Makita and Hitachi) are equipped with a shock absorber system between the handle and the engine block.
It is particularly effective and absorbs shocks really well.

Use a one handed chisel punch.

The Ryobi is the only one that does not have an auxiliary handle. Light and compact, it can be used with one hand without problems, but beware of frequent torque returns when the drill gets stuck.

Carry out a vertical drilling with a hammer drill.

The Hitachi is favored by its high weight on vertical holes.

Perform a chiselling with a perforator.

With their big size, the Makita and the Hitachi lack maneuverability in function chisel.

The equipment

LED lighting on a chisel punch.

Bosch, Dewalt and Ryobi machines are equipped with a led lighting. It is particularly effective on the Ryobi.

Attach a three-jaw chuck to make some holes.

For some holes (in wood or metal) or to screw / unscrew, you must add a three-jaw chuck, which accepts smooth tipped drills. It is supplied with the Hitachi.

Secure mandrels
To avoid the rise of torque in the forearms during drilling, each perforator is equipped with a secure disengaged chuck. That of Ryobi is not, and the returns in the arm are well felt. Fortunately, the machine is light and therefore easy to master.

The points to take into account to make the right choice

  • To be manoeuvrable, the wireless perforator must not be too heavy. The battery represents about 50% of its weight. As an example, the Ryobi, with its 18 V battery, weighs 2.4 kg, the Hitachi and its 36 V 4.3 kg battery.
  • The perforators are delivered with chargers capable of analyzing the battery. Indicators provide information on the status of the batteries before and during charging: out of order, power supply problem, charge level... Some chargers are air-cooled (AEG, Bosch, Hitachi, Makita) which shortens the time to charge and extend the life of the battery.
  • A auxiliary handle, to be mounted on the drilling head, is supplied with each machine. It allows to have more support force during drilling and chiselling. The Ryobi does not have one, and it's missing in some situations, even if it's light and uses one hand without problems.
  • Except the Ryobi, all the perforators are sold in a hard case.

The evaluation criteria of the 6 chipping drills

  • Piercing efficiency concerns the different types of drilling and the maximum capacities given by the manufacturers. We dwelt on the perforation in concrete and stone to test the endurance of the machines.
  • Chipping is often useful, even if with these tools, do not expect to drop a wall. But they are enough to rectify an angle, make a bleeding or enlarge a piercing...
  • The battery and charger are essential elements. We conducted the tests until the batteries ran out, which overall showed good battery life. The charging time has been checked as well as the ease of use of the chargers.
  • The comfort of use takes into account the good slip-resistant cladding, the quality of manufacture, the maneuverability, the installation of the tools and the flexibility of use of the orders. Finally, the vibrations in perforator mode have been tracked.

Test procedure *

The machines were tested on vibrated concrete sidewalk curbs 30 cm thick and on an old limestone wall.
The holes were executed without pre-hole, with two and four-sided double-helix concrete drill bits of Ø 10, 16, 18, 20, 24 and 26 mm, for a drilling length of 15, 20 and 39 cm.
The tools have been changed to test the flexibility of the rings.
The drilling took place vertically and horizontally to control the handling of the perforators.
The test was concluded on chiselling.
* System D test benches are made under real conditions of use by our journalists. The results may therefore differ from those displayed by the manufacturers, whose tests are performed by laboratories according to standardized protocols.

What to remember from the test?

Cordless perforators are quite efficient and offer good autonomy.

  • Arrived first, the Dewalt displays a nice homogeneity. Very compact, it is cut for intensive work and the maximum drilling diameter of 24 mm is impressive.
  • In second place, the Bosch loses some points on the maximum diameter of drilling.
  • Third, the Makita is a safe bet, despite a coal engine that requires maintenance and consumes more.
  • In fourth place, tied, theAEG is powerful and theHitachi robust and enduring. Both of them, however, struggle a little on the big diameters of drilling. On the other hand, the consumption is correct.
  • The Ryobi close the march. But his price is unbeatable and he has quite successful tests. It remains however rather intended for occasional works.
