This wiki has been updated 17 times since it was first published in November of 2018. Many people look at rusted beams and car chassis and think, "junk." But those who are equipped with one of these handy needle scalers know that old metal can be brought back to like-new condition with just a bit of elbow grease. If you restore old vehicles, boats, or engines, these tools are a necessity. We've included both bayonet and pistol types to suit every need and working environment. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.

Editor's Notes

March 16, 2021:

After taking some time to review our previous picks for this page, we eventually determined that all of our existing choices were still great selections, so there was no need for us to make any major changes to these rankings.

The most substantial alteration we made was replacing our top-placed Ingersoll Rand 125 with the upgraded Ingersoll Rand 125-A Standard Duty, which looks to have a design very similar to its predecessor, although this one promises improved durability via virtue of a reengineered spring.

For alternative options to combat corrosion, maybe you’ll be interested in checking out our list of sandblasters or chemical rust removers.

March 08, 2021:

Though it had been some time since we last updated this list, it turns out that it didn't matter. After carefully reviewing the other options on the market, we couldn't find any better models that deserved to usurp a spot from one of our current recommendations. We were hoping to be able to include an electric scaler at this time, but there simply aren't any available yet that we felt comfortable including, so for the time being, it looks like you will have to stick with a pneumatic model and an air compressor.

December 01, 2018:

While a needle scaler's ability to effectively remove rust, paint, mill scale, and weld spatter was a top priority, we thought it just as important to focus on a tool's durability as well. We believe that a tool that functions extremely well, but breaks after a couple of uses is almost more disappointing that one that doesn't work at all for its intended purpose. At least the latter doesn't get your hopes up in the beginning just to dash them unexpectedly.

Special Honors

It is capable of up to 3,000 blows per minute for quick material removal. ingersollrand.com
