Chainsaw Chain Specs Explained, Understanding the DL Meaning

Chainsaw chain DL stands for drive links, which are the small, tooth-shaped tabs located on the underside of the chain that run around the guide bar.

"Drive links are what allow the saw's clutch and sprocket to pull the chain around the bar, functioning like the teeth in a clockwork's cog," experts note.

These links are distinct from the sharper cutting teeth on top of the chain where the actual wood-cutting takes place.

When replacing a chainsaw chain, you will typically encounter the DL count alongside two other critical metrics, pitch and gauge.

Why Drive Link Count Matters for Safety

Pitch refers to the spacing between chain rivets, while gauge indicates the thickness of each drive link's lower tang to ensure proper compatibility.

Chainsaw safety and performance heavily rely on having the exact DL count to prevent dangerous operational hazards during use.

A chain with too few links will not fit the guide bar even with the tensioner fully loosened.

Conversely, a chain with too many links remains dangerously loose even after adjustments, creating serious risks.
