How to Choose the Best Straight Grinder?

  • What type of straight grinder you want?

The pneumatic or air-powered straight grinders are quite different. You will always have to carry an air compressor with you if you want to operate this tool. Compressor delivers compressed air that runs the motor and then the rotary head of the grinder.

This type of tools is suitable for in-house grinding, polishing, and sanding, deburring, derusting, and buffing jobs. You should not choose a pneumatic straight grinder if you do not own an air compressor.

  • Build quality:

The second most important thing you should consider is build quality. Different brands use different materials to produce the components for their power tools. You should invest your money in a grinder that can offer at least 2 years’ problem-free service.

Not all the electric die grinders are designed to offer such a long-lasting support. Therefore, you should look for the specs that increase the lifespan of a straight grinder, such as air exhaust slots, outer housing, collet size and quality, and other safety features.

  • User-friendliness:

Every straight grinder is powered by a different type of motor. Some motors can produce up to 28,000 RPMs and some only up to 25,000 RPMs. Power matters when you are going to work longer in your workshop.

You would not like to deal with a grinder which does not generate enough rotation speed to finish the ongoing work in time. Therefore, you should carefully check the speed before you place the order. You should also check the controls to ensure you can easily turn on and turn off the grinder.

  • Budget:

Some power tools promise unmatchable quality and performance but their cost is too expensive. Some straight grinders are quite affordable but you cannot find reliable information on their manufacturers. Such issues often trouble the customers.
