Suitable for operators seeking long service life and reliable cutting performance in hard ground conditions.
Digger Supply 21LH + 21RH Carbide Teeth
Product Type: Carbide Trencher Cup Teeth. Fit: Chains with 2″ pitch. Material: Steel. Identified as a quality aftermarket option with carbide tips, these teeth are designed to deliver enhanced durability when penetrating rocky soils. The paired LH/RH configuration supports even wear distribution and stable performance during continuous trenching operations.
Digger Supply 5LH + 5RH Carbide Teeth
Product Type: Carbide Trencher Cup Teeth. Fit: 2″ pitch chains. Material: Steel. This set provides a compact LH/RH pairing suitable for smaller or lighter-duty trenchers while still offering carbide advantages for rocky soils. A practical choice for mixed ground conditions where durability matters but chain wear remains a concern.
Digger Supply 9LH + 9RH Carbide Teeth
Product Type: Carbide Trencher Cup Teeth. Fit: 2″ pitch chains. Material: Steel. The 9LH/9RH pairing is intended for operators who need balanced wear and dependable cutting action, especially when soils contain moderate rock fragments. Carbide tips offer extended life compared with standard steel teeth.
Digger Supply 15LH + 15RH Carbide Teeth

Buying Guide
- Ground conditions: Carbide tips excel in rocky soil and hard clay, where standard steel teeth wear quickly. Choose higher carbide content or specialized bullet teeth for extreme conditions.
- Pitch compatibility: Ensure teeth match your trenching chain pitch (commonly 2″ in professional trenchers). Mismatched teeth can reduce performance and increase wear.
- Left/Right orientation: LH/RH or 5LH/5RH configurations promote even wear and smoother cutting. Consider sets that include both sides for balanced life.
- Tooth geometry: Bullet or cup shapes influence penetration and breakout resistance. Bullets may excel in tough rock, while cups provide stable cutting in mixed soils.
- Maintenance: Regular inspection for wear, cracks, and carbide loss extends tool life. Clean blades and re-sharpen as needed following manufacturer guidelines.
- Availability: Stock levels and aftermarket options vary. If a specific pattern is backordered, assess alternative 2″ pitch carbide teeth with similar geometry and material.
- Cost vs. durability: Carbide teeth typically cost more upfront but can lower total cost of ownership by reducing downtime and replacement frequency.
- Brand and compatibility: Trusted brands and verified compatibility with your trencher model reduce the risk of fitment issues and performance inconsistencies.
- Safety and handling: Wear protective gear when installing or removing teeth. Follow torque and installation procedures recommended by the equipment manufacturer.
When selecting rock teeth for trencher work, operators should weigh soil hardness, rock content, and trenching speed. Carbide-tipped options from reputable sellers often deliver extended life in challenging ground, though availability and exact fit depend on the trencher model and chain system in use. The products listed here are commonly compatible with 2″ pitch chains and are designed to balance performance with durability across a range of trenching tasks.
