A pack of 10 replacement 4-sided solid TC cutters for the spiral cutter block fitted to the Axminster Workshop AW2260S planer thicknesser. Each cutter has four edges, when a cutter eventually dulls, simply turn the cutter through 90°, retighten the screw and you're ready to go again. Each cutter's edge will last around 10-20 times longer compared to standard high speed steel planer blades.
