Welding Angle Grinder Buying Guide
If you are considering the purchase of an angle grinder then you should compare the following things about the different grinders to find the perfect one for your needs.
The size of the disc that an angle grinder uses will determine the size of the cuts you can make with the tool. Larger discs make larger cuts and smaller discs make smaller cuts.
The amount of wattage the angle grinder has will tell you how much power the tool has. The increased wattage of a grinder indicates that the tool has an increased amount of power and will be able to cut through materials that are denser or thicker.
If you buy an angle grinder that has the option of multiple speeds then you will be getting a tool that you will have more control over and be able to use in more applications.
If an angle grinder has a motor that is brush less then you can expect the grinder to be more durable and last longer than the grinders that are powered by motors with brushes.
You can buy angle grinders that are powered by 110V, 220V, or battery. The 110V powered tools are commonly seen at work-shops and business locations. The 220V and the batter powered options are usually seen at a private business, or homeowner work locations. The battery-powered grinders are cordless and much easier to maneuver and use in awkward places.
Additional Safety features
If the angle grinder has a slow start, anti-kickback, or paddle switches listed as one of their features these are all safety-related elements to protect the user.
Frequently Asked Questions
Q. What can I do with an angle grinder?
An angle grinder can be used to smooth welds and make welding projects more aesthetically pleasing. You can also use an angle grinder to cut ceramic tiles, pavers or stucco to get a better fit.
You can sharpen blades using one of these tools, or remove rust and corrosion from metal objects. The angle grinder can even be used to remove loose paint when you are preparing a surface for painting.
Q. What is a grinder in welding?
In welding, there are times when slag is created. This is excess material that causes the weld bead to appear lumpy instead of smooth flat and uniform.
A grinder is a machine that removes this excess material and makes the weld bead smoother and more attractive. It functions a lot like a high powered sander with a specialized wheel for removing and sanding metal components.
Q. Does grinding a weld weaken it?
You do not weaken the weld by grinding it unless you remove some of the parent materials when you remove a portion of the weld bead. If you do remove any of the weld beads then you do make the strength of the weldless.
If welds are properly executed then they will be as strong as the parent materials they are created from and connected to. Grinding can be performed to remove slag and dress a weld up as long as too much of the weld bead is not removed from the surface.
If you are looking for an angle grinder that has the highest power to weight ratio available then you want to consider the Dewalt DWE402. The 11,000 RPM motor provides you with the utmost in power for a tool its size.
The Makita XAG04Z is an excellent choice if you are looking to buy a battery-powered angle grinder. The battery-powered tool does not have a cord to interfere with your access to the area you need to work in. It is powerful and durable, and it takes a standard 4 ½” grinding disc.
