It matches the standard 7-spline configuration used by multiple saw models, making it a versatile option for mixed-tool shops.

Buying Guide
What to check before buying a 22mm spline drive sprocket:
- Correct bore and spline: Ensure the inner hole is 22mm and the spline matches your saw’s drive hub (7-spline, small-spline, etc.).
- Pitch and teeth: Confirm chain pitch (3/8″ vs 0.325″) and the number of teeth to match cutting needs and chain type.
- Brand compatibility: Some brands favor specific sprockets for optimal engagement. Check your model’s recommended parts.
- Durability vs price: Metal rims offer durability; consider environments (seasonal work vs. occasional use) when evaluating value.
- Replacement availability: Ensure the product is readily available and shipped to your location for maintenance planning.
