How to Choose Bucket Tooth I


Few components of a loader, backhoe or excavator can do more to help or hinder your productivity than the Bucket Teeth. So, how can you wade through the multitude of choices on the market today? The key is to match the tooth and the adapter, or shank, to your machine and work. If your are the one whose work involves excavator, luckily, this article will tell you how to choose right bucket tooth.

First, you need to know how is the bucket tooth made. Generally speaking, there are three types of bucket tooth, say, forged teeth, cast teeth, and fabricated teeth.

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.

Cast teeth are made from austempered 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.

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

As a rule, the shape of the tooth determines it's life and use. Each teeth 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: This is 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 bucket 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, the longer the tooth will last before it needs to be replaced.

However, bucket tooth 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. Bucket tooth 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.
