1. The hole enlargement of the saw blade

When cutting wood, in order to adapt to different sawing machines and different processing requirements, some users will choose to enlarge the central bore and pin holes. In fact, many manufacturers have designed different apertures for different sawing machine models when producing woodworking saw blades. However, if the aperture of the woodworking saw blade you purchased is not suitable for your sawing machine, or you want to adapt to more processing needs, you can also perform hole enlargement.

2. How to enlarge the hole

The hole enlargement of the woodworking saw blade is not complicated, and you can do it in the following ways:

• Use a hole enlarger

The hole enlarger relates to a professional knife tool for enlarging small holes. Secure the woodworking saw blade to the workbench and use it to slightly move along the edge of the hole to enlarge the hole diameter.

• Use a drill

If there is no hole enlarger, it might be easier to use a drill to enlarge the hole. Fix the woodworking saw blade on the workbench and use a drill with a suitable diameter to slowly enlarge the hole diameter. However, it should be noted that this is still producing a tremendous amount of heat when using a drill. The approach to cooling is very simple: and carry the heat somewhere else by using water. In addition, the method may easily cause wear of the saw blade speeding up.

3. Does hole enlargement affect the sawing effect?

Hole enlargement will not have much impact on the sawing effect. If the hole size after enlargement is suitable for your saw machine and processing needs, the sawing effect should remain unchanged.

It should be noted that it is not recommended to frequently enlarge the holes of woodworking saw blades. On the one hand, enlarging the holes may reduce the surface flatness of the woodworking saw blade and accelerate the wear of the saw blade; on the other hand, too frequent enlargement of holes will also have an adverse effect on the service life.

4. Conclusion

Woodworking saw blades can be used to enlarge holes, but the maximum attempts for it is not an option. Therefore, confirm the saw machine and processing requirements before enlarging the hole so that the appropriate hole diameter can be matched.
