The shape of the tooth determines it's life and use. Each tooth will have varying degrees of three factors. Matching the right level of these factors to your job will enable you to work as productively as possible.
Factor 1：Wear life
The ability to withstand wearing, scouring and abrasive action of the material being handled. Wear life is obviously determined by the construction and the material of the tooth, but just as important is its shape. The shape of the tooth determines how much wear surface comes in contact with the dirt or other material being dug or loaded.
The more wear surface a tooth has, then the longer that tooth will last before it needs to be replaced, however teeth with a lot of surface area don't always have the most efficient penetrating surface and can make it more difficult for the bucket to power through hard, compacted ground.
Teeth with high wear life may be more appropriate for loading and material handling applications due to their long life, whereas for digging and trenching high penetration and impact is usually more important.
The ability to penetrate tough material, when it's tightly compacted, rocky or frozen. The best penetrating tooth is typically a sharp pointed end, often referred to as a Tiger Tooth. Teeth with high penetration that also have high impact are best suited to digging and trenching applications as they enable the bucket to more easily penetrate material.
How well the tooth stands up to penetrating shocks and high breakout forces. Simply put, how sturdy is the tooth and how will it hold up on a powerful digging machine. Teeth with high impact are best suited for digging and trenching applications when using an excavator, backhoe or other machine with high breakout force.
Hopefully this will allow you to make a more informed decision when selecting a tooth system.
