Best Angle Grinders for Welding
An angle grinder or disc grinder is used extensively in metalworking. First developed in 1954 by Ackermann + Schmitt (now FLEX tools), its unique design was the first to place a grinding disc in the horizontal position. From preparing surfaces prior to welding to grinding down welds (or slag) after, this tool is indefensible for every welder. Cutoff wheels, sanding and brushing attachments further add to this tool’s utility.
In most cases though, you’ll be using your angle grinder to clean rust off or mill scale and smooth out ragged edges. This helps create a stronger weld that is less likely to crack or be porous. Angle grinders are often much faster in cleaning off metal than a wire brush, and they take less effort, too. For welds that will be visible, grinding also helps to finish, polish and finalize the joint.
If you don’t own an angle grinder or are looking to replace an old one, we’ve put together a great list to help you out. Here are some of the best Angle Grinders on the market that you may want to consider before making a purchase.

Powered by a 11,000 RPM motor that gives it the power needed to grind down just about anything you can throw at it, yet it’s still very affordable and budget friendly. The DWE402 does weighs six pounds, so while it’s a bit heavier than some, it’s built solid and made to last.
