Crosscut Saw Blades The negative hook angle of radial-arm and sliding miter saw blades pushes the stock downward and against the fence to provide an extra margin of safety. If you own a sliding miter saw or a radial-arm saw you’ll want a crosscut blade that is specially designed for these machines.

What does Hi ATB mean?

High Alternate Top Bevel (Hi-ATB) For extra-fine crosscutting and for materials prone to chipping, such as melamine, hardwood and laminate flooring and fine hardwoods. The high bevel accentuates the razor sharp slicing action at the edge of the blade and provides a sandpaper smooth finish.

What is a negative hook angle?

While a positive hook angle is great for ripping, a negative hook angle is better for crosscutting. The negative face of the tooth is much less likely to cause chipping in the surface of the wood as it’s oriented in a counter-rotation direction.

What is the hook angle on a saw blade?

Saw blades come in a range of hook angles. If the teeth lean forward (facing into the cut) the blade has a positive hook angle. If the teeth lean backward, the blade has a negative hook angle. Most saw blades for woodwork- ing have a hook angle ranging from -5° to 20°.
