How We Research

Updated on

Every guide on Best Angle Grinder Online starts with one question: will this tool suit the person who is shopping for it? For grinders, that means the jobs you have, the discs you plan to run and whether you want a cord or a battery.

Here is how we answer it.

1. We start with your job

Cleaning rust off a gate, cutting a bolt and sharpening a mower blade all call for different setups. A big 7 inch grinder is the wrong tool for light work in a tight spot.

We check the size, the power and the switch type. When your project limits the choice, we say what to look for.

2. We compare specs and features

For angle grinders we look at disc size, amps or voltage, no-load speed, switch type, guard design, side handle and weight. For cordless tools we also check whether a battery and charger come in the box, since many bare tools don't include them.

For bench grinders, die grinders, sanders and rotary tools we check the matching details, like wheel size, collet size, pad size, speed range and what comes with the kit.

DeWalt, Milwaukee, Makita, Bosch and the others describe their tools in their own words, so we name the brand for every claim. We also note the warranty terms the maker lists.

3. We look at buyer feedback

We read what buyers report after using a tool. We look for patterns, like switch problems, overheating, short battery life and loose guards.

One angry review doesn't sink a product. A pattern does.

4. We score each product

Our score weighs specs, features and buyer feedback against what you're shopping for. A tool that is great for one reader may score lower in a guide written for another.

Scores spread out on purpose. A 10 is rare.

5. We keep pages up to date

Products change, and some disappear from stores. Makers sell close models and kits under similar names, so we check each model number and what comes in the box, and we only link new units.

We skip unknown brands with no track record and any tool with a known recall. When we update a guide, the "Updated on" date at the top changes with it.

What our picks are not

Our picks are research, not lab tests. We don't claim to have used every tool we cover.

Grinders can throw sparks, kick back and shatter a damaged disc. We don't call any tool safe or easy, and we label maker claims as the maker's claims.
