Abstract

The present invention relates to a saw blade, and more particularly, in view of the situation that the saw blade is worn out by cutting the wood using a conventional saw for cutting wood, the present saw is disposed of the saw blade (2) (3) When the tip is worn, it relates to a saw blade that can be broken and used for a certain length.

Description

Saw blade {SAW BLADE}

The present invention relates to a saw blade, and more particularly, to a saw blade that can be used by breaking a predetermined length of the end of the saw blade teeth when worn.

In general, when cutting a wood using a saw for cutting wood, the saw is cut to the wood by repeatedly pushing and pulling a certain force against the wood. Among the pushing and pulling operations, the pushing stroke is a subsidiary stroke for pulling, that is, the saw is generally cut by the cutting stroke. During this cutting, there is a slight difference depending on the cutter, but it is mainly cut (cut) by the inner part of the saw blade. As a result, as shown in part A of FIG. Therefore, when the front part is worn out, there is no cutting work efficiency, and most carpenters who are workers discard the saw.

In order to solve such a problem at one time, the present invention aims to allow the saw blade (2) to be broken by a predetermined length when the teeth (3) end portion is worn.

1 is a perspective view of the saw blade of the present application, FIG. 2 is a side view of the present application, and FIG. 3 is a B-B cross-sectional view of FIG.

In normal saw blade,

When the end of the tooth 3 of the saw blade 2 is worn, it is characterized by forming a plurality of cutting lines 4 to be broken by a predetermined length.

The cutting line 4 is characterized in that it is formed diagonally.

The cutting line 4 is provided with a groove 5 having a predetermined depth in the longitudinal direction so as to be easy to break.

Example

If the wood cutter wears the end of the teeth 3 of the saw blade 2 due to long use of the saw, it may be used by breaking the cutting line.

By cutting the diagonal cutting line, the tip of the saw blade is sharp, so that it may be conveniently used for cutting a simple curved portion as shown in FIG.

The saw blade of the present invention has an effect of improving cutting efficiency by breaking and removing the worn end during the wood cutting process;

Considering that the conventional end is worn out and discarded, it can be said to be a very advantageous design.

Claims (3)

In normal saw blade, Saw blades characterized in that a plurality of cutting lines (4) are formed so as to be broken by a predetermined length when the teeth (3) end of the saw blade (2) is worn. The method of claim 1, Saw blades, characterized in that the cutting line (4) is formed diagonally. The method of claim 1, The cutting line (4) is a saw blade, characterized in that to form a groove (5) of a predetermined depth in the longitudinal direction in the cutting line so as to be easy to break.
