Hi, this is Eric with TechShop, and another edition of Tool Showcase.

I’ve got a treat for you today, something new from Aircat Pneumatic Tools.

This is the model 6390 Compact Needle Scaler.

Some of you might be wondering what this does and I’m going to show you in just a minute.

I have to admit I went for many years without one of these and when a tool dealer told me about them, it was like the best thing since sliced bread.

A needle scaler is designed to remove rust, scale and paint and I can tell you from experience they can be huge time savers.

This new model from Aircat features 4800 blows per minute, a 1 ¼ inch stroke and a durable steel housing in a lightweight compact design.

It really has a nice, machined look to it and a clean finish. Call me crazy, I know it’s going to get used but I like a good looking air tool.

I’ve installed the air fitting and added the prerequisite drops of oil, plus I’ve got my safety glasses and hearing protection, so let’s hook it up and check it out.

You can see how it made short work of the rust and I use these a lot on brake drums and rotors.

I also like the knurled grip; it makes it easy to hang on to.

So if you’d like more information about this and any of Aircat’s many other tools, visit

How to Maximize Cooling System Efficiency (VIDEO)

Do everything you can to help the system operate as intended. This video is sponsored by Rislone.

Today's cooling systems manage heat loads instead of reacting to them after they happen. These intelligent systems will look at calculated engine load, throttle position and more to determine the best course of action. These real-time countermeasures help to keep combustion chamber temperatures at optimum levels for the best possible combustion event. The condition of the coolant has a direct relationship on the health of the cooling system. The coolant additive packages contain wetting agents or surfactants, which reduce surface tension and allow the coolant to transfer heat more efficiently. The cooling system has an important job in street cars, but it's even more critical in heavy-duty or high-strain applications. Whether we're talking about heavy-duty trucks, work vehicles, or sports cars which see routine, spirited or track driving, their cooling systems will need to hold up to even harsher conditions. If the goal is to keep temperatures in check, then we need to do everything we can to help the system to operate as intended.
