75CL066E Oregon Square Ground Chisel 3/8 .063[1.6mm] 66 drive links

Oregon 75CL is a square ground full chisel chainsaw chain designed for maximum cutting performance in professional applications. As the standard sequence version of the 75CJ, it delivers the same aggressive square-ground cutter design but without the full skip layout, making it ideal for users who want the fastest cutting speed with a full complement of cutters.

Square ground chain is regarded as the highest performing chain available, offering approximately 15–20% faster cutting than standard full chisel chain along with excellent stay-sharp properties. It is especially suited to clean timber and high-output saws where maximum productivity matters. Sharpening requires specialist square-ground files and precise angle control, so experienced users often use a Granberg clamp-on file guide or dedicated sharpening setup to maintain correct cutter geometry.

Not commonly available from other chainsaw chain retailers.
