Instructions: Sharpen the saw blade

After frequent use, you will find that the saw blade needs sharpening or replacement.
However, it must be clarified in advance whether you actually always have to buy a new saw blade immediately or whether there is a possibility of sharpening the old saw blade again. What’s the procedure?
Below you will find the relevant information on what is important when sharpening a saw blade.
Detection of the blunt saw blade
A significant indicator of a blunt saw blade is the recognizability of heat marks on a workpiece. This increases the duration of the cut and the effort required to drive the saw blade into the workpiece also climbs.
In addition, the corners are torn out and the result of the cut is unsatisfactory. The risk of jamming or recoil of the saw blade is increased. This creates a high risk of injury for you at the same time.
The hints for a blunt saw blade
You will notice a slow saw speed . The interfaces are discolored and at the same time show an unclean cut. The sawdust is very delicate . A comparison with the cut of a very filigree toothed saw blade is actually given. In addition to the higher volume when sawing, you will notice vibrations . In general, hearing protection is required when working with a chop saw.
Vibration and flutter show an imbalance. This high risk should not be underestimated, because the high speeds during the rotation can cause the saw blade to burst.
Sharpening the saw blade
You should only machine blades for circular saws . If the teeth have no particular hardening, you can try to sharpen the saw blade by hand and a diamond file. However, sharpening saw blades still includes numerous additional measures.
Dressing saw blades
Dressing is required because after a few grinding operations, the teeth have been slightly changed in their format. Few teeth are shorter than others and would not produce the necessary cutting performance between the longer teeth.
When dressing, the teeth are brought back to almost the same length to ensure that all teeth can be cut. You can do this yourself. Some machines also do this.
The setting of saw blades
In addition to the frequent dressing, a cabinet is occasionally required. The teeth are alternately bent on both sides . This creates a wider saw cut later than the original saw blade. This prevents the saw blade from tilting when sawing.
Locking tools
Classical pliers are used for the cupboards . The limitation is a problem. You can only achieve uniformity with enough practice. Closet devices for the blades of the circular saw are recommended . They are available in specialist shops.
A professional setting device bends the teeth of the circular saw pliers in order to maintain a flat format and this ensures a uniform setting of the blade. As a rule, these devices are available in specialist shops from around 80 euros.
With very voluminous blade diameters, problems can also arise with the cabinet devices. In some cases, very voluminous sheets no longer fit in the device.
Professional grinding of circular saw blades
If you have circular saw blades professionally sharpened, trimmed and set, you save the effort and costs. As a rule, it is advisable to buy devices if you often have to sharpen the saw blades and the saw is used very often .
When sawing firewood with a seesaw, frequent sharpening is required. Here it is definitely worth buying your own sharpening device. Frequent sharpening of the saw blade is also necessary when sawing wood with numerous nails .
Only a blunt saw blade does not require a new purchase. Nevertheless, you should examine the saw blade for damage as well as broken and bent teeth. Cracks are an unmistakable sign and you should actually set aside the budget for a new saw blade.
