How Do I Choose The Right Saw Blade

saw blade is a main parts of Reciprocating saw.a good saw blade will make you do more with less. safe cuts with reciprocating saw depends on having the right blade for the tool and for the type of cut you want to make.

Blade Tooth Configuration

The shape of the saw blade tooth and the way the teeth are grouped is one factor to affect the way the blade cuts. The configuration of the teeth on a saw blade has a lot to do with whether the blade will work best for ripping, crosscutting or laminates.

Flat-Top (FT)

Flat-top teeth are used on blades for ripping hard and soft woods. Because wood is much less likely to chip and splinter when it is being cut with the grain, a rip blade is designed to quickly and efficiently remove material. The flat-top tooth is the most efficient design for cutting and raking material out of the cut.

Alternate Top Bevel (ATB)

This means that the blade teeth alternate between a right- and left-hand bevel. This configuration yields a smoother cut when crosscutting natural woods and veneered plywood. The alternating beveled teeth form a knife-like edge on either side of the blade and make a cleaner cut than flat-top teeth.

Combination Tooth (Comb)

Combination blades are designed to do both crosscutting and ripping. The teeth are arranged in groups of five four ATB teeth and one FT with a large gullet between the groups.


Triple Chip Grind

The TCG configuration excels at cutting hard materials such as laminates, MDF and plastics. Teeth alternate between a flat "raking" tooth and a higher "trapeze" tooth. The TCG configuration is also used for non-ferrous metal cutting blades.

High Alternate Top Bevel (Hi-ATB)

The Hi-ATB configuration is used for extra-fine crosscutting and to cut materials surfaced with melamine, which is prone to chipping. The high bevel angle increases the knife-like action at the edge of the blade.
