Chip Free Cuts In Plywood
Are you pulling your hair out trying to get chip free cuts in plywood with the super thin veneer we are getting these days.
In addition to using a saw blade with a high ATB grind on the teeth and a zero or near zero hook angle on your saw blade, a zero clearance blade insert supports the plywood as the blade exits the plywood giving it support right up to the edge of the blade. Use one for different kerf blades and one for bevel cuts from 0 to 22-1/2 degrees and one for cuts from 22-1/2 to 45 degree cuts.
If your saw is not 220 volt powered try using a thin kerf blade if your splitter or riving knife will allow it. With a thin kerf blade you have less drag on the motor keeping the R.P.M.’s up and allowing the saw to cut better by maintaining the proper speed. A few of my favorites are the Tenryu Miter Pro which has a .118 kerf or the Diablo D1080x which has a .098 kerf. Both of these blades have an alternate top bevel as well as a alternate shear face so they work more like a spiral router bit slicing the wood.
