The diameter of each needle also differs. Usually, the more needles it has the more rusts or area of rusts it can knock off in one go. The number of needles can range from 12 to 19. Air needle scalers usually come with different number of needles on each one. Needle size and quantity is also something you need to consider. Personally, I generally prefer the pistol grip handles, since you can easily grip it better and apply more pressure on the surface you’re working on, especially when working in an open area where space is not a concern. So, consider the handle you’re going for when choosing an air needle scaler. No matter the type of handle it comes with, a longer unit will be hard to fit into tight quarters. You should also consider the total length of the tool when making your choice. You can easily slip that under your truck and knock off some rust from the frame or chassis. On the other hand, they fit more into tighter spaces because of their streamline design. Straight handles however can also be held pretty easily, but you can’t apply the same amount of pressure on the tool and surface you’re working on as when you’re using one with a pistol grip handle. On the other hand, they’re often larger, heavier and can be quite difficult to use in tight spaces, like under your truck. Pistol grip handles are generally easier to hold, and it’s fairly easy to apply more pressure on the surface you’re preparing while using one with a pistol grip handle. These two handle types offer different advantages and disadvantages. A pistol grip handle, and a straight handle. There are two types of handles you’ll have to choose from. One of the first things most pros consider when choosing an air needle scaler is the type of handle it comes with. Here’s what you should consider before choosing a pneumatic needle scaler for your projects Type of handle or grip What to Consider When Choosing an Air Needle Scaler When using it however, you should wear gloves and a suitable eye protection as the needle scaler can cause the rusts or weld slags to fly everywhere randomly. Then you can move on to another area and so on. To start scaling the surface, hold it at an angle of 45 degrees to the work surface and work it across the surface, taking care not to cover too large an area at once.Ībout 2 or 3 passes over a 6 or 8 inch area is usually enough to clean that area. This you can do with solvents or a combination of fresh water and ditergent. There are other methods of scaling or removing rust, old paint and other foreign materials off the surface of metal, but the needle scaler has advantage over the rest because each of the needles adjusts itself to the contours of the material being cleaned, which makes it ideal for scaling irregular surfaces.īefore using it on any surface however, it’s important to prepare the surface first by removing any greese, chemicals, oil and any water-soluble contaminants. We’ve reviewed several models in this article with each of them offering different numbers of needles, operating speeds and power levels. These needles moving at these speeds force chips of every dirt, rust and old paint off the surface. When connected to a compressed air source, the tool forces these needles against the metal surface it’s applied on at variable speeds up to around 5000 times per minutes measured in BPM (Bumps Per Minute). The needle scaler comprises a set of very fine chisels which are known as the needles.
