How to choose the right bucket teeth for the job

Matching the bucket teeth on your excavator, loader or backhoe to the cut of the job can reduce wear and tear on your bucket and bucket.

Very often, the teeth in a new bucket are not suitable for your particular job. To make the right tooth choice, consider the type of material you intend to move and the job your equipment will be performing.

Hardening materials extend the life of teeth

  • The harder the tooth material, the greater the resistance to wear, abrasion and impact, and the longer the wear life.
  • Special casting and heating techniques combined with certain material types, such as cast austenitic ductile iron (ADI), can produce teeth that are stronger but lighter in weight. Backhoes, excavators and loaders use ADI bucket teeth for medium to high intensity work.
  • Made from ductile iron, the grinding teeth can withstand the high wear conditions caused by handling sand, gravel and rock. While the wider tip provides additional penetration of the filling material, the additional wear surface combined with the ductile cast iron extends the life of the teeth.
  • Backhoes, excavators and graders can also be used with assembled standard teeth.Inconel-molybdenum alloy steel self-sharpening teeth offer an economical solution for general applications.
  • Depending on the application, forged, high-strength, hardened bucket teeth are also available for loaders, scrapers, excavators and backhoes. Forged teeth made from carbon, chrome, nickel and molybdenum steels are designed to resist wear and impact and offer greater durability and higher tensile strength than standard types of ductile iron teeth.

Shape: its length (and width)

  • The length and shape of the bucket teeth affect their performance. Shapes include progressively blunter, wider teeth and narrower teeth with sharper tips. Each shape changes the rate at which the tooth is consumed, or the percentage of dirt, rock or other material that comes into contact with the entire tooth. Wide bucket teeth place a greater surface area on the material and are suitable for general loading and digging applications. Teeth with a larger wear surface usually last longer.
  • However, the greater surface area does not result in the ability to penetrate compacted, frozen or rocky materials. Trenching and digging require tapered bucket teeth with a pointed tip. As the sharp teeth penetrate the material, less hydraulic and fuel consumption is required to drive the bucket through the material.
  • The flared universal bucket teeth can withstand moderate impact and wear conditions while leaving the smooth ground required for trenching. Jobs involving high impact and rock prying require shorter bucket teeth.

Penetrating teeth

  • Penetrating softer, denser materials, such as clay, requires bucket teeth with cross-edge tips and central ribs to provide additional support.
  • Penetrating harder materials, such as sedimentary rocks, cemented gravels and poorly shot rocks, requires single pick teeth with a sharp triangular point.
  • Some tasks involve hard, hard-to-penetrate materials that normally require fracturing. Double-ended bucket teeth remain sharp and provide maximum penetration, while being used primarily as angular teeth.
