What causes sparks when grinding?
While grinding metal, sparks are produced because of Friction. The rotating grinder cuts through the metal molecules, rubbing against them and producing heat. Some particles get loose in this process and burn because of this heat.
Can sparks from a grinder start a fire?
Can an Angle Grinder Cause a Fire? Cutting metal with an angle grinder causes a lot of sparks. However, the sparks that result are not that serious of a fire hazard. The only way a fire could start is if the sparks happen to fall continuously on the same spot of highly flammable material.

Typically the sparks that come off of an angle grinder are small and very light, because of this the spark is usually small enough to cool down before it hits bare skin. However, the larger hot sparks from grinding metal are much more dangerous, since they usually are larger, and possibly consist of burning metal.
Do sparks from a grinder hurt?

You can stop this happening by making sure you are using the right wheel for the material, and have set the right speed.
Why do we need non sparking cutting tools?
Well look no further. Our Non-Sparking tools mean there’s no more worrying about heat and sparks in EX areas! There are many occasions where traditional grinding and cutting tools are totally unsuitable due to things such as heat and spark creation.
What kind of connection do you need for air grinder?
All of our tool bits are to be used with an air tool with 1/2″ connection. Slower rotational speeds (only 750 – 4000 rpm) mean that less heat is generated. This grinder offers both a grinding surface and a cutting edge in the same tool.
How many types of grinders do we have?
We have 4 different types of grinders in our Non-Sparking line: the Flapdisk Grinder, the Giant Series, the Cutting Grinder and the DIE Grinder which has 6 different bit shapes. There are many reasons why our tools are unmatched: our tool head consists of a strong alloy which is then coated with a special layer to make it even stronger.
