404 Pitch, Gauge and Length Dimensions of a Chainsaw Chain

There are many types of chainsaw chains - the key to choosing the right one is understanding its three core dimensions: pitch, gauge and length. Each of these can be measured and compared to ensure that the chain you buy fits your tool properly.

Pitch

The spacing between the cutting teeth in a chainsaw chain is called its "pitch," and it determines how well the tool can drive the chain around the guide bar. This can make a big difference in the amount of wood that can be cut by the chainsaw, and how fast the tool can cut it.

A chain with a larger pitch is typically faster and more efficient than one with a smaller pitch. This is why you'll see these larger pitch chains on the top professional chainsaws and models used by fire departments and first responders.

However, bigger pitch sizes require more power to drive the chain through the bar and into the wood. This can mean that the power head and engine will be more heavily loaded, which can reduce its lifespan.

Chains with smaller pitches can also be more energy-efficient and require less power to drive the chain. They're ideal for tasks where the amount of wood removed is less important, or for battery-powered tools.

Gauge

The thickness of a chain's drive links is a major compatibility factor, and it's important to make sure that the replacement chain you purchase has the correct gauge for your tool. If the new chain has a gauge that's too thin, it won't fit in the grooves on the guide bar and could jam up your tool. On the other hand, if the chain has a gauge that's too thick, it might be too stiff to drive the chain around the bar.

If you're unsure about which chain gauge is compatible with your tool, check out the specifications on the packaging or in your manufacturer's manual. It's also a good idea to try the chain on your tool before purchasing it so that you can feel its weight and measure its length.

Full Chisel

A chain with a full chisel cutter design is great for cutting long, deep cuts on chainsaw bars that are 24" or shorter. These chains have a wide space between the teeth, which provides more room for the wood chips to follow the chain out of the wood and expel from the cut. This helps them work more efficiently and produces a cleaner cut.

Semi Skip

A semi skip chainsaw chain has more teeth than a full skip, but not as many as a standard skipping chain. This arrangement allows the wood shavings to clear from the cut more effectively, while still delivering more cutters than a skipping chain.

This chain is a great choice for professional woodcutters who use a bar that is over 24". It's also the chain of choice for most Oregon chainsaws, with LubriTec oiling to keep your chain and bar well lubricated while you're working.
