Cutting Edge
The front wear component of a bucket that penetrates material first, typically bolt-on for field replacement.
The cutting edge (also called blade or lip) is the bottom-front steel component of a bucket that makes first contact with material. It's designed as a replaceable wear item, protecting the bucket shell from damage.
Types:
- **Standard flat edge**: General-purpose digging
- **Bolt-on reversible**: Can be flipped when one side wears
- **Weld-on edge**: Welded in place, for less aggressive applications
- **Half-arrow edge**: Enhanced penetration for hard materials
- **Serrated edge**: For frozen ground or root cutting
Material:
- Standard: Hardox 400 (400 HBW)
- Heavy Duty: Hardox 450 (450 HBW)
- Extreme: Hardox 500 (500 HBW)
Cutting edge selection affects:
- Penetration force required
- Bucket fill factor
- Wear life
- Operating cost per tonne moved
