Grinder Buying Guide

Grinder Power Source

There are many different types of grinders available on the market today. No matter the grinder type, there must be a source of power in order to make the grinder work. To make sure a new grinder meets your expectations, the power source should be taken into consideration. Grinders may be electric, battery, or pneumatically powered with larger, commercial grade grinders being fuel powered (diesel, gas, propane).

Electric Grinders

Electric grinders are powered by electricity and require being plugged into a power outlet. While this may restrict the grinder’s portability, electric grinders are also much more powerful than battery operated, or cordless, grinders. Depending on the projects you’ll be working on, having a more powerful grinder may be essential to achieving high quality results.

Cordless Grinders

Cordless Grinders are battery operated, making them very portable. However, they are not as powerful as other grinder types and are only available in hand-held models. The battery will also require periodic charging. For projects that require only light use of a grinder, the portability and convenience of a cordless grinder may suit your needs best.

Pneumatic Grinders

Pneumatic grinders are powered by air. They are typically hand-held grinders that combine power and precision and are excellent for when delicate grinding in needed. Manufacturers often refer to pneumatic grinders as air grinders.
