How to Choose Suitable Bucket Teeth


Few components of a loader, backhoe or Bucket Teeth can do more to help or hinder your productivity than the teeth on the bucket. So, how can you wade through the multitude of choices on the market today? The key is to match the bucket teeth and the adapter, or shank, to your machine and work.

How is the bucket teeth made? Well, there are three main types of bucket tooth:

1. Forged teeth are made from high quality alloy steel. Heat treated to offer maximum resistance to wear and impact. Over 50% more wear life over fabricated teeth.

2. Cast teeth are made from austempored ductile iron. Heat treated to offer maximum resistance to wear and impact. A cost effective alternative to the standard forged tooth, strong and lightweight in design. Self-sharpening.

3. Fabricated teeth are made from alloy steel. Through hardened for resistance to wear and impact. Self-sharpening.

Generally, 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.

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. Bucket 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. However, they are not always the best tooth for providing a smooth bottom to a hole or trench and you should weigh the full needs of your job when choosing a tooth system.


How well the bucket teeth stands up to penetrating shocks and high breakout forces. Simply put, how sturdy is the bucket teeth 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.
