When cutting any board always use the thinnest blade you can, a thicker blade will try to part the board more as it cuts, put it under more stress and create rub marks on the bevel, particularly at the end of the cut as the blade is retracted. Putting a board under more stress means the blade is under more stress and so is the framer! Â Â More blade stress = more blade bending.
Using a thin blade (providing it is set up properly) will glide through the board making it easier on your hand/arm/fingers and produce a clean straight cut. The only time I have had to go for a 015 blade is if the board is over 3000 micron but even then this, as in all cases, should be supported by a little experimentation.
