Buying Guide

Our hammer drill buying guide has compile to provide you with the best possible advice on your purchase. In our opinion, there are some important criteria to take into account when choosing the best Bosch cordless hammer drill that will meet your needs.

The Type Of Hammer Drill

There are two models of hammer drills that stand out, the corded hammer drill and the cordless hammer drill. Your choice will depend on how you want to use it.

The Power Of A Hammer Drill

The impact drill allows you to drill and screw in soft, hollow materials and the hardest materials such as stone, concrete, and brick, thanks to the percussion function. 

There are different models for occasional, regular, or intensive use. The more powerful the drill, the easier it will be to drill and screw in tough materials like concrete or stone.

The Chuck Of A Hammer Drill

Corded and cordless hammer drills all have a chuck that allows you to install a bit or bit. There are different types of mandrel depending on the desired use:

  • The Diameter Of The Chuck – Hammer drills mainly have two diameters; 10mm and 13mm. The 10mm chuck allows drilling and screwing with small bits in small diameters  ( around 10mm in metal and concrete, 20mm in wood. As for the 13mm chuck, it offers much larger drilling and screwing diameters ( maximum capacity around 13mm in metal, 16mm in concrete, and 45mm in wood ). Choose according to your use of a drill.
  • The Self-tightening Chuck – This option is ideal for your screwing and unscrewing because it offers the possibility of changing bits quickly. It is the most common today on impact & hammer drills.

The Weight And Ergonomics Of A Hammer Drill

Using a hammer drill can be difficult with a heavy model. I advise choosing a model with a weightless than 2kg. The lighter the impact drill, the easier it will be to carry out your work at height, at arm’s length, and in time. 

Today there are models of drills weighing less than 1kg like those of the Bosch brand.

The Battery Of A Cordless Hammer Drill

The vast majority of cordless hammer drills now work with Lithium-Ion batteries, providing sufficient voltage and ampere for your day-to-day home and DIY jobs.

The Lithium-Ion battery – This technology makes it possible to have lighter drill batteries, which recharge more quickly. Typically, the batteries charge between 30 minutes and 90 minutes, depending on your model of the hammer drill. These Lithium-Ion batteries are useable in medium and high-end impact drills.

Battery Voltage – The voltage on impact drills is between 10.8V and 20V to date. The higher the voltage, the more powerful your hammer drill will be. We suggest a minimum power of 14.4V.

Battery Intensity – Like voltage, the greater the intensity ( measured in Ampere Ah ), the more powerful your battery will be and will last longer. Today there are models of impact drills with an intensity between 1 Ah and 5 Ah. I recommend at least intensity of 3 Ah.
