Excavator Sharp & Tiger Teeth

Both are pointed profiles; the two labels come from the source references rather than from a fixed standard. The practical difference is tip geometry and the amount of material behind the point, which is why the listed photographs should be compared against the tooth being replaced. Send the part number or a dimensioned photograph if two references look close.

A narrow tip concentrates force, so it is the wrong choice where the difficulty is impact rather than penetration: solid rock, blocky ground or demolition material will break a pointed tooth before it wears out. Penetration profiles are also more likely to be lost or broken when used outside their intended conditions. Keep standard or heavy-duty profiles for that work.

Yes. A narrow working edge carries less wear volume than a full standard profile, so a pointed tooth normally has a shorter change interval even in the same material. The trade-off is deliberate: better penetration in compacted or frozen ground in exchange for more frequent replacement.

Where a drawing or sample is available, yes. A longer, thinner tip penetrates more easily but has less material behind the point, so it breaks more readily and wears through sooner; a shorter, fuller tip trades penetration for life. Send the required tip geometry, connection details and quantity so the profile and tooling can be reviewed.

That is where they are most useful. A pointed profile breaks into hard layers with less breakout force, which is why sharp and tiger forms are used in compacted soil, hard clay and frozen ground, and why they put less load on the machine than a wide standard tooth.

Corner positions usually take the hardest penetration load and wear faster than the centre, so pointed profiles are often fitted at the corners with standard teeth through the centre. Fitting every position with pointed teeth gives maximum penetration but shortens the overall change interval. State the bucket arrangement and the ground so the mix can be reviewed.
