What Does an Excavator Bucket Mean?

General Classification of Heavy Machinery Bucket Teeth

  • The general condition of excavator working bucket teeth directly affects the productivity of the equipment, and if their integrity is optimal, it will minimize the mechanical stresses transmitted to the machine and increase productivity, thus extending service life and reducing maintenance costs.
  • A common mistake made by owners of excavators, backhoes and other earthmoving equipment is to use the same type of bucket teeth for different tasks without considering the nature of the material being moved or its characteristics. This limits the efficiency of the machine in achieving high productivity, increases wear and tear, and minimizes the life of multiple components.

Consider the following factors before selecting the type of teeth you will use in your machine.

  • Tooth excavation range.
    The structural design of the tooth is related to its excavation range. Analyzing the type of soil, for example in dense, rocky or frozen terrain, the best choice is a sharp or pointed tooth, as it has a smaller contact surface with the ground and allows the restoration tool to penetrate the material effectively. On the other hand, teeth with relatively wide tips are used for less compact surfaces or for working with materials.
  • Impact resistance.
    Bucket teeth are designed differently depending on the degree of wear of the work they will perform. To choose the right bucket teeth, consider the nature of the soil.
  • Some machine manufacturers offer their tooth classification systems, and you should contact your parts supplier to learn about their characteristics and uses, but in many cases, you can identify any of the following types in any brand.
Tooth type


Tooth Type: Universal
This is the default configuration for excavator buckets and its use is ideal for loose or loose surfaces with low to medium wear and low to medium impact levels. Its primary use is for trenching.

Suitable for excavators in loose terrain with low wear and versatility. Designed to achieve trenches and finishes. Impact: medium-low.

Tooth type: digging


Suitable for excavators working on dense surfaces with high wear and impact, requiring high levels of digging, such as ice, rock. It has the disadvantage of low service life.

Tooth type: Double jaw


They are used for highly compact surfaces with high impact levels, with a higher level of digging than the previous examples, and are recommended for execution in low wear environments.

Tooth type: Chisel


Widely used in excavators requiring low to medium penetration and impact, they have a long service life and an optimal digging range in the above mentioned soil types, but they are not recommended for abrasive materials.
