Buying Advice
We've created this section for first-time shoppers who are still confused. Here, we'll briefly discuss a few specs that you should know before buying. Knowing your specs gives you a clearer understanding of how your angle grinder works, and lets you find the right one for your project.
Which Wire Wheel Brush do I Need?
Knotted Wheel Wire
Knotted wires use twists of metal wire, or knots to operate. This brush supports aggressive cutting and absorbs vibrations and bending that might lower the wire's quality.
Standard brushes are twisted to about two-thirds of the device's filament length. The other third is slightly flared. With larger applications and sizes that need a tougher brushing action, the knots can twist for the entire length.
Knotted wires are known for their versatility. They are also known as cable twists and is used in oil pipelines and oil fields. With knotted wires, you can use your grinder to complete the hardest cutting tasks with ease.
Crimped Wire
Crimped wire brushes consist of stainless steel, carbon steel, or brass filaments that look pinched, wavy, or bent. When grinding metals normally, small wire pieces break off and leave cutting edges open. Crimps solve this problem by creating cleaner breaks. They support uniform brushing because of the tool's filament tips helps its cutting action.
Most crimped wire brushes have a 2" arbor hole that works with shafts ranging from ½" to 1". These brushes are available in various sizes, but the most common diameters are 6" to 8". Get a crimped wire if you're a novice user who wants clean cuts when completing your daily grinding tasks.

Angle Grinder Considerations
Speed Ratings
The speed rating of your grinder is directly correlated to the RPM of your motor. A good grinder has an RPM of 5,000 to 11,000. While this means your tool is efficient at grinding and cutting at high speeds, you still need to remain careful.
Comfort
You want an angle grinder that's ergonomic and easy to use. Having a grinder that doesn't fit well with your hands will increase your exposure to injury. Unless you have a large job that requires a very high-speed angle grinder, a smaller angle grinder model is preferable.
Look for an angle grinder with an anti-vibration handle. This keeps the machine steady and in place while you're working. Do this to make your projects safer and easier to complete.
