FAQ: Applications

Can I use a right angle grinder to get a linear finish?

A belt is your best option for a linear finish. If you need to use a right angle grinder for the finishing application, we would recommend our Z-WEB hook & loop discs.


Why are my wheels not lasting as long? I keep needing to use more than one.

The product you’re using might be too soft for the application. We recommend using a hard bonded wheel, like PREDATOR cut off wheels or PREDATOR grinding wheels.


My wheel is not cutting straight pieces. What could be the problem?

You may need to check your tool to see if everything is secure and not worn down. Another reason could be that the product is too hard, and you need to try a softer wheel.


I was working on a project and the metal started to burn. What do I do?

We recommend using your tool at the max power, or you need to go with a product that is softer. Always remember to check RPM guidelines for safety. You may be running too hot.


I’ve been on this project forever. Why is my product so slow to cut?

There are a couple of reasons why this could be happening. You may not be using the right tool with the recommended RPM speed, or you need to use a coarser grit. Another suggestion would be to apply more pressure. If you are using a wheel, a softer bond would be a better choice for this problem.


My cut off wheel broke during the application. What can I do to prevent this from happening?

My cut off wheel broke during the application. What can I do to prevent this from happening?


My product keeps glazing while I’m working on a project. What causes this, and how can I prevent it?

Glazing can occur once the product starts wearing out and there no sharp grains left. You could be using the wrong product for the job, or using it incorrectly. We recommend a coarser grit (36-40) for a heavier operation. If you are using a wheel for the job, always remember to use a soft bond for tougher applications, and hard bond for the lighter applications.


The work piece material keeps adhering to the product and it’s hard to finish the job. What can I do to prevent this?

This instance is referred to as loading. To prevent this, we would recommend using a grit of 36-40, and open your work space more for any issues with debris.


What type of conditions should grinding tools be stored?

To make sure you don’t cause damage to any tools, store them on a dry and level surface.


Am I able to store my machine with the disc still fitted on?

We highly recommend that you remove any product attached to a tool before storing. Any product stored with a tool attached could cause damage and safety issues later.


I have a disc I was wanting to use, but it looks damaged. What should I do.

We recommend to stop using any damaged product and throw it away to ensure that no one else will use it. For added safety measures, always make sure to check and inspect any product for damages before use.


Should I use a different guard when cutting with an angle grinder, other than the one used for grinding?

You can use an open guard for grinding, but FEPA recommends that a guard that covers both sides should be used for any cutting. Always remember to use a guard to fight debris and promote safety.


Is there anything I can do about premature loading/clogging?

ARC’s exclusive grinding aid, Performance Coating, can be baked into some abrasive products to reduce grinding temperatures and prevent loading when working with softer metals like aluminum. Plus materials with additional grinding aids are available.


What is the proper way to store coated abrasives?

The backings and resin bonds are sensitive to change in temperature or humidity and should be kept in cool, dry areas. These products should be stored in their original container in temperatures between 60-80 degrees Fahrenheit and 35-50% relative humidity.


What applications are non-wovens used for?

Blending, cleaning, finishing, light deburring and stock removal, polishing, rust/oxide removal, scrubbing, & scuffing


What does arbor size mean?

Arbor size is the size or diameter of the shaft on the tool.


What does RPM mean?

RPM stands for Revolutions Per Minute. It is the rotational speed of the tool.


What materials are non-wovens used on?

Aluminum, Mild Steel, Stainless Steel, Titanium, & non-ferrous metals.
