1 - 4 Joules: Small rotary hammers (for light work, such as drilling into walls)
4 - 10 Joules: Medium-sized rotary hammers (for heavier tasks, such as drilling into concrete)
10 - 40 Joules: Heavy-duty tools (for very heavy tasks, such as concrete demolition)
40 - 60 Joules: They are used for medium-sized demolition, for removing pavements, or on very hard materials.
60 - 100 Joules: These compressors are suitable for industrial applications, such as large-scale demolitions and heavy drilling tasks in hard materials.
Over 100 Joules: The very large hydraulic hammers and compressors in this category are used in mining and very large-scale construction or demolition. They are capable of penetrating extremely hard materials, such as rocks and heavily reinforced concrete.
