What Is a Spot Weld Cutter?

Factors to Consider Before Buying Spot Weld Cutters

Are you wondering how to choose the best spot weld cutter for your needs? Here is a list of factors that you should consider!

What Materials Were Used to Make the Cutter?

The majority of manufacturers go with steel as the preferred material. However, you probably know that steel can be of different quality.

If you are looking for a cutter that will be most durable and long-lasting, go with M2 steel. It provides the strength and sturdiness that can handle even the strongest welds.

Although you can’t say that it is expensive, an M2 steel spot weld cutter kit is among the priciest out there. It is why only premium brands like Blair decide to use it.

Other manufacturers use steel of various quality, and that directly affects the durability of the set. It is why you should ensure to go only with top-quality steel.

How Many Cutting Blades Are There?

You can encounter different spot weld cutter sets out there. Depending on the manufacturer, the sets will have a different number of blades. Since cutters come as a kit, the chances are you will receive at least two cutting blades in the box.

Some companies are generous enough to include a large number of blades and top that up with a budget-friendly price.

It is vital to check the number and specifics of the blade included in the cutter set. You want to ensure that the components perfectly fit your needs. It is the only way of turning the purchase of a spot weld cutter into a long-term investment.

Warranty

It doesn’t matter which project you are buying; a warranty is an important indicator of quality. It shows you whether the manufacturer trusts its product. The general rule is that the longer the warranty, the better.

However, you also want to consider that affordable kits usually have a lower quality than premium sets, which justifies a shorter warranty.

Here is where the brand also plays an important role. You want to stick with a reputable manufacturer because you can be certain they will follow the warranty promises.

Shady companies might offer a generous warranty, but they are not ready to provide support when you need it.

How to Use a Spot Weld Cutter

Once you purchase a cutter for spot welds, you will need to learn how to use it. The working process is quite simple. The device has a tiny centering pin that gets in touch with the panel. Thanks to that, the cutter keeps its position.

Since there is a spring for the pin, you need to apply pressure to start cutting. If you are familiar with wooden hole saws, the cutting wheel reminds of them. Please note that you can choose another cutting head from the set, and you should do that in case you didn’t pick a suitable one.

As you apply pressure, you will notice that the device cuts through the panel. The reason why spot-welding cutters are so popular is that they are the most accurate way of cutting these welds.
