Tool News/ Helical Cutter Heads The buzz for home jointer and planer owners is the helical or spiral cutter heads.
A true "spiral" blade cutterhead uses a curved HSS blade. Instead of slamming the blade straight into the wood the blade engages only a small section at a time as it turns, "slicing" the wood off. This allows it to deal with wild grain with little to no tearout.
A helical head imitates this action with a series of small cutterheads arranged in a spiral pattern. Each cutter is rotated slightly, so that one corner hits the wood first, then the rest of the cutter shears off wood as it moves forward, mimicking the shearing motion of the spiral blade.
