How to Choose Bucket Tooth II


Penetration: The ability to penetrate tough material, whether 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 tooth with high penetration that also has high impact is best suited to digging and trenching applications as it enable the bucket to more easily penetrate material. However, it is 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.

Impact: 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. Bucket teeth with high impact are best suited for digging and trenching applications when using an excavator, backhoe or other machine with high breakout force.

In addition, it also need to choose the right retention system. The way you mount the tooth to the adapter(shank) can determine how firm the tooth will stay over time. It will also determine how easy the tooth is to replace when worn.

1. Flex pin - Horizontal: Flex pins are two steel forgings that have a neoprene rubber in between. As you pound the pin through, it squeezes the neoprene and that holds the tooth up on the adapter. Installed and removed properly, flex pins can be re-used up to 10 times.

2. Flex pin - Diagonal (Rhombic System): Using a slightly longer flex pin than the horizontal mounting system. The rhombic system mounts the tooth and flex pin at a 45 degree angle. This makes installation and removal as easy as the vertical system while providing the strength of the horizontal system.

3. Roll pin - vertical: This looks like a steel coil. The pin is pounded down through the top rather than through the side. Roll pins are not re-useable and must be replaced along with each bucket tooth installation.

4. Crimp on: The sides of the Bucket Tooth itself are crimped into impressions on the adapter. This is a more cost-effective option for smaller less-powerful machines.
