There are many theories in the industry on the best way to prolong fingerjoint cutting knives to have them produce a better chip load. There are just as many ways in practice that don’t follow the recommended guidelines too, like fewer teeth that can add life, but may also reduce output quality. Another approach is to compare the three types of fingerjoint cutting knives available for your wood production need: HSS, carbide and PCD (polycrystalline diamond). Beyond the investment for a 25x or up to 500x run rate, are there other advantages to consider that could be a reason to switch?

Naturally sensitive to moisture, wood shrinks when moisture is lost, which can result in warping and twisting. The amount of shrinkage depends on the wood species and also on the pattern of the year rings or growth rings.

When choosing a blade, here are a few things to consider: 1 Diameter: This is measured from the furthest edge of one tip to the furthest edge of the tip directly opposite. Use the saw diameter the machine was designed for. Even if the material being cut doesn’t require the depth of cut you will get from the proper size blade, you want the rim speed attained by a full diameter blade.
