Traditional chainsaws used chains that were fitted with scratcher teeth. The large teeth were packed tightly together to prevent them from biting too deeply into the wood. However, the chains were extremely slow until the invention of the chipper chain by Joseph Cox. It uses curled teeth, which has depth gauges in front of each tooth to prevent individual teeth from cutting too deeply.
While modern chains like those featured on our website use a more advanced type of teeth (full and semi-chisel teeth), chipper teeth still play a significant role in modern chains. Most of the chainsaw chains from Oregon for example feature semi-chisel teeth while those from Stihl (Stihl twelve-inch Picco Super chainsaw chain) have a full chisel tooth. Semi-chisel teeth have rounded corners, which reduce the cutting sharpness. But, they maintain the appropriate level of sharpness when cutting hard, frozen, dirty or dry wood. Full chisel teeth make the cutting of soft, clean lumber efficient as the sharp edges cut through the wood fibres fast.
Another critical aspect to factor in when buying chainsaw chains and bars is the depth gauge. Modern chainsaw chains should have the appropriate gauge height for a safe and efficient operation. Depth gauges that are too high may not allow the chainsaw to cut fast because they make a shallow depth for individual cuts. Low depth gauges, on the other hand, increase the risk of kickbacks significantly.
The gauge of the saw chain should range from 0.05” to 0.063. Most of Oregon’s chainsaw chains in our stock have gauges measuring 0.043 inches. Note that the saw chain gauge should match the gauge of the chainsaw’s guide. It is because thick chains may not fit while extremely thin ones often slip sideways and may not cut correctly.
The pitch also makes a crucial aspect when buying chainsaw chains and bars. It defines the distance between two rivets and is calculated by measuring the space between three rivets (most rivets don’t have a similar length apart) and dividing the value by two. Our saw chains have a pitch of .404, .325 and .375 inches.
The chain should fit the chainsaw bar appropriately. Most saws have lengths that range from 6-20 inches. Gardening activities require small electric saws while activities like felling large trees need professional-grade saws with lengths of more than twenty inches.
