Product Reviews

Given the vast choice of spot weld cutters, choosing the best 5 was a challenge. Here are our favorites.

1. Blair 11096 Cutter Set

Best Professional Spot Weld Cutter

Very few spot weld cutters can compare with the Blair cutter set. It is the best choice for professionals. This set is highly popular and comes with three 0.375-inch cutters, as well as a “skip-proof” arbor pilot and a spare pilot should you need it.

The blades are double-ended, which means they cut more efficiently, putting less strain on the cutting blades and preserving the life of the cutter. When the bottom teeth dull, simply switch the cutter over and use the second set of teeth.

This set fits 0.50-inch hand drill chucks, so they are pretty much universal, and they are manufactured from high-grade M2 steel, meaning they hold their sharpness for longer.


  • M2 quality steel.
  • Popular with professionals.
  • “Skip-proof” pilot.
  • Spare pilot.


  • Expensive.

The blades are 0.375 inches in size, which seems pretty standard for spot welds, and because it comes with 5 blades, you never need to worry about the cutters dulling.

What Is a Spot Weld Cutter?

A spot welder is a tool that transfers heat through copper alloy electrodes to weld two or more sheets of metal without the use of additional filler. The heat comes from an electrical current.

Spot weld cutters are specifically designed to remove those spot welds without using a rotary cutter, making the job neater, faster and easier.

Spot welding is one of the oldest welding methods, and it works best with thin sheet material, which is why you see it commonly used in the automotive manufacturing industry. It is also an ideal method of making temporary welds.

Things to Consider (Buying Guide)

It is a challenge defining what makes the best spot weld cutter in one word. Several factors are at play here, but there are some basics you should consider.


There are several brands of spot welder cutters, and they all claim to be the best. Some are more popular, with higher customer satisfaction and sales figures. This translates into a higher price tag for the very best.

The brands to look out for are Blair, KCC and Grizzly, to name a few.

How Many Cutting Blades?

The amount of cutting blades you get with your spot weld cutter matters. Most brands offer a choice of two blades as part of their package, but if you need to widen your choice, make sure that you can purchase additional blades separately. If not, this will severely restrict the versatility of the tool.

You also need to know that these spares are affordable and won’t break the bank.

Quality of the Materials

The materials used in the spot weld cutter’s manufacture make a massive difference in how it performs and its longevity. Blair weld guns use M2 steel, which is durable and hard-wearing, while KCC also offers high-quality steel in their manufacturing process.

The quality of the components is vital if you want a spot weld cutter that lasts decades instead of a couple of years.


Price could be first, middle and last on the list. It all boils down to the budget. How much do you want to spend on your spot weld cutter? The truth is, you get what you pay for. The quality of the materials used, the warranty and the tool’s capabilities are all affected by the budget.


Warranties translate into peace of mind. The longer the guarantee the spot welder has, the less the machine ages, and the longer you get to use it hassle-free. Check each brand for its warranty, as it will vary enormously between them.

Always try and get the best warranty you can.

How To Use a Spot Weld Cutter

Locate the spot welds you want to remove, and using a drill and small bit, drill a pilot hole in the center of the spot weld. Sweep away any strands of metal. Insert your weld cutter into the same drill, and using the pilot hole as a template, drill down until the teeth have ground away from the weld material.

Some kits have centering tips included to make neater and more accurate cuts. The best cutters will leave the spot weld smooth and burr-free.

Spot Weld Cutter FAQs

What Is Squeeze Time in Spot Welding?

Squeeze time is the interval between the electrode’s initial application on the material and when the current is applied. Squeeze time is necessary because it delays the current until the force of the electrode has reached the correct level.

How Far Apart Should Spot Welds Be?

The recommendation is that the spot welds should be at a distance equalling 10 times the material thickness. This helps to attain adequate joint strength and to take account of any overlaps of the sheet material.

What Is the Best Way To Remove Spot Welds?

The best way to get rid of spot welds is to use a spot weld cutter. With a drill and a pilot bit, you find the center of the spot weld and drill through. Then, with the cutter tool, you can easily remove the excess weld material, leaving it burr-free and smooth.

How Do You Drill Through a Spot Weld?

Using a drill and set of drill bits is an easy way to drill through the spot weld. However, it can punish the bits and wear them down somewhat. The easiest way is to start with a small bit as the pilot and graduate to a larger size, using the pilot hole to centralize the bit.

It might take longer to do it this way, but it is cheap and easy to do.

Can I Spot Weld With a MIG Welder?

You can spot weld with a MIG welder, but you must first purchase a dedicated torch nozzle and a pair of locking clamps. You also need two drill bits. You can buy a complete kit for this very purpose.

Line up the panels and measure where you want the weld to be. Mark the spot and separate the panels. Using the drill bit, drill the hole through the top panel. You now have the recess where the weld can sit. Realign the panels and measure the next spot and so on.

Repeat this process until you are ready to weld. Use the clamp set and hold them in place, positioning the torch nozzle over the spot. It’s now time to start spot welding.

A Cut Above the Rest

If you are working on a car or restoring a classic, sometimes you need to make light work of spot welds to remove rusty panels. A spot weld cutter does this and also stops you from butchering the panel by trying to pull it apart, causing unnecessary damage to your project.

Get a spot weld cutter and make your life easier. It could be one of the best investments you make.
