Caterpillar Digger & Excavator Bucket Teeth

Good, sharp bucket teeth are essential for ground penetration, enabling your excavator to dig with the least possible effort, and hence the best efficiency. Using blunt teeth greatly increases the percussive shock transmitted through the bucket to the digging arm, and hence also to the slew ring and undercarriage, as well as ultimately using more fuel per cubic metre of earth shifted.

Why not bolt-on teeth? Ultimately, a two part tooth system offers greater versatility of tooth types, and also greater strength, since the adapters are welded to the bucket’s cutting edge.

Why bother with different types of tip? The notes above give some indication of this, but basically it is the best way to ensure tooth breakage/wearcosts are kept to a minimum, and to ensure you’re not wasting fuel by struggling to dig with blunt or incorrect teeth.

Which is the best tip? There is no ‘best’ tip, and tip choice is not an exact science, particularly in varying ground conditions. However, if you use the best compromise for your particular job, and review the criteria regularly, you can save a great deal of time and effort. Remember that tips may be swapped before they are worn out, and kept aside for future use.

What machines can they be used on? Basically, there is a size of tip and adapter to fit all excavators from 1.5 to 80 tonnes. Many machines are already fitted with this system, but if not, it is a relatively easy job to weld the adapters onto the bucket edge and convert.

What if I want a flat edge? If you need to dig a flat base to a trench, you can weld a cutting edge across a set of tips to form an 'underblade'. These can be swapped for standard tips at any time, and re-fitted when you next need to use a straight edge.
