Types of Saw Blades

Types of saw blades and the cuts they make

Blade teeth are of two general types: Tool steel or carbide. Carbide is harder and holds a sharp edge much longer.

Band Saw Blade

A straight blade welded into a circle. Used mainly at sawmills & steel service centers. Preferred over circular saws due to less waste.

Crosscut

In woodworking, a cut made at (or near) a right angle to the direction of the grain of the workpiece. A crosscut saw is used to make this type of cut.

Rip cut

In woodworking, a cut made parallel to the direction of the grain of the workpiece. A rip saw is used to make this type of cut.

Plytooth

A circular saw blade with many small teeth designed for cutting plywood with minimal splintering.

Dado blade

A special type of circular saw blade used for making wide grooved cuts in wood so the edge of another piece of wood will fit into the groove to make a joint. Dado blades can make different width grooves by addition or removal of chipper blades of various widths between the outer sadaio blades. This first type is called a stacked dado blade. There is another type of dado blade capable of cutting variable width groove. Das. An adjustable dado utilizes a movable locking cam mechanism which causes the blade to wobble sideways more or less. This allows continuously variable groove width from the lower to upper design limits of the dado.
