Timberline Tungsten Carbide Cutters are designed specifically for the Timberline Chainsaw Sharpener. All sizes are usable and interchangeable with the sharpener without changing any parts.
Ask any machinist and they will tell you tungsten carbide is extremely tough and durable and will outlast any hardened steel file period. Because of its durability it is difficult to claim an exact lifespan. However, much testing and customer feedback allows us to confidently claim a minimum of 30+ sharpenings. Users may very well exceed 100+ sharpenings with careful use by not binding the carbide cutter and always spinning clockwise.
It is recommended to sharpen the chain often instead of waiting until it is extremely dull. This will make sharpening even faster with a quick touch up while reducing wear on both the carbide cutter and the chain itself.
