1 Penetration is key
The amount of surface area that contacts the ground during penetration determinesthe efficiency of the tooth. lf the tooth has a larger width or a blunt surface area,more excavator power is needed to penetrate the material, more fuel is used, andmore stress is placed on all machine components.
Penetration teeth are self-sharpening by design, sharpening itself as it wears. Topenetrate tightly compacted ground, rocky or frozen conditions, you will need longpointed "y” teeth called Spikes' or Double Spike' teeth. Others include reinforcedpenetration teeth with extra wear material. These tooth profiles enable the bucket topower through the material with ease while digging and trenching, but because theyhave less wear material in them compared to say abrasion teeth, their service life isshorter. Don't expect penetration teeth to do clean-up work!

2. Hold on tight during high impact conditions
Bucket teeth with high impact resistance can withstand penetrating shocks and highbreakout forces. These are best suited for digging and trenching appliions whenusing an excavator, backhoe or other machine with high breakout force, particularlyin hard rocky conditions and rock quarries.
Getting the material out of the ground quickly is important, but good tooth-adapterfitment is key to reducing impact stress on the tooth system and bucket. Poor tooth-adapter fitment creates a huge amount of pressure on the pin which can result inweakness and instability, ultimately causing fractures or the pin to drop out!
