I’m trying this blade as a replacement blade in my Lamello top 20. The Lamello blade has only two teeth with a positive hook, the other four have a negative rake. In comparing the cut between the two blades, I found that the CMT blade cut a little closer to the top surface of the material, which is no big deal, and that the CMT slot was a little narrower, so that the biscuits fit tighter.
CMT makes a range of top-quality replacement blades for popular biscuit joiners. CMT blades have an orange PTFE coating to prvent pitch buildup. Use the chart below to help select the correct blade for your needs.
