Hollow-ground circular saw blades can produce super-smooth cuts with all types of woods. In fact, the cuts can be so smooth that these blades are often referred to as "planer" blades.

But....use them improperly and the result will be excessive heat build-up ...burning of your workpiece edges...and binding that could bring your cut to an immediate halt as your saw stalls and fuses pop.

Here's the trick. Where most saw blades are designed for use with their tips breaking the wood surface by only 1/8" to 1/4", hollow-ground blades are designed to be adjusted so the blade projects through the workpiece much further....at least to the bottoms of the tooth gullets...even further if possible.

This is due to the fact that he teeth of hollow-ground blades typically have no set. As a result, a slight projection of only 1/8" to 1/4" will not provide sufficient blade side clearance to prevent this binding and burning.
