Notes for key dimensions on type 1 & type 3 teeth:

Type 1: All that is required is dimension ‘A’, although dimension ‘C’ is useful. Dimension ‘B’ is not applicable.

Type 3: The side-bolt holes are of little concern when identifying this type of tooth, and the only dimensions required are as per those of the type 2 tooth. In other words ‘A’, ‘B’ & ‘C’.

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 adaptors 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 accross 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.

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.

All the bolt-on teeth in our range are in stock in our warehouse, and are supplied complete with nuts and bolts as necessary.

IMPORTANT! When ordering teeth and/or side cutters, you MUST check and specify dimensions 'A' and 'B' in order to ensure you receive the correct parts.

If the effort of burning off old bolts, and bolting on new teeth seems too much, you could always convert to our replaceble tip type teeth. Once the adapter is welded onto the cutting edge, you can swap or replace tips quickly and easily.

Type 1 Type 1:
Single leg, bolt or weld-on tooth

Type 2 Type 2:
2 leg, bolt-on tooth

Type 3 Type 3:
2 leg, bolt-on side cutter (corner tooth) supplied in pairs

Type 4 Type 4:
Weld-on, hardened casting, for use as side cutter, or between teeth on cutting edge

Type 5Type 5:
Weld-in blade forging, for use as side cutter on larger excavator buckets




The Caterpillar type side-pin tip and adapter system is a tried and tested formula, and offers wide choice of tip styles and exceptionally good value for money. Our 'non-genuine' equivalent to the CAT system is the most popular choice both on our new excavator buckets, and for customers repairing existing bucket, because as well as being very well priced, it is easily available worldwide, since you can also buy the (compatible) genuine article through your local friendly Caterpillar dealer.

Replacement tips are most easily identified by the length and diameter of the lock pin.

Short 'R' style tip Short 'R' style tip
For all general purpose applications. A good strong tip, with low unit cost.

Long 'R' style tip Long 'R' style tip
A longer wearing general purpose tip, but with less ultimate strength than the Short type.

H.D. Abrasion 'R' style tip H.D. Abrasion 'R' style tip
For high impact, high wear applications, where Short or Long wear or break too quickly.

'V' Sharp, Penetration tip 'V' Sharp, Penetration tip
Essential for penetration in extremely hard ground conditions.

'V' Sharp, Penetration tip Weld-on adapter

'V' Sharp, Penetration tip Retaining pin & split washer



Along with replacement bucket teeth, we also stock a range of standard 230-240 HB cutting edges for general bucket repairs, in the following sections:

Prices start from under £70 + VAT including delivery.

Edge stock

These edges are suitable for bucket repairs and fabrications for most general plant, construction and agricultural equipment, (up to 9 tonnes operating weight) for buckets and dozer blades.

We can also supply purpose cut bucket blades in larger sections - from 25, 30, 40 or 50mm thickness - in either Boron steel or Hardox.
