About ETA


When you need a specific industrial tooling product, like a tap arm, isn’t it nice to talk to someone whose entire company is based upon expertise in that one product and it’s correct application and understanding of how that will help your operation? Isn’t it also great not to have to pay through the nose for that product? Contact us and find out just how nice it is.

When Ergonomic Tool Arms, LLC was started, our goal was to produce a simple, smooth operating, well made tapping arm. To make the best arm possible it was absolutely necessary to machine all the components and assemble everything right here where we had full control and could delivery quickly.

Rather than make a huge number of models to handle larger and more difficult threading operations we strive to do just a few things very well. Thus currently we offer only tapping for threads in the Size 1 Adapter range. See
Tap Adapters. If your requirements involve threads beyond the range of our TA-Series Tap Systems we would be happy to refer you to our very capable competitors.

Right from the beginning we had the confidence to offer a
3 year warranty against excessive wear, regardless of the number of cycles. After 5 years on the market we are happy to note nothing but a few minor claims against that warranty. With some periodic maintenance on the tapper motor itself, you can expect the ETA Tap Arm System to provide many, many years of perfectly tapped holes. See System Details.

What about you and your company? If you are on the front lines of product or component manufacturing then your bottom-line depends upon wise capital investment in tools and equipment. It also depends upon productive, injury-free workers producing your products efficiently and without defects. We understand that completely. Compare our price and quality to others and you will make the right choice. Also see our
3 Year Warranty.

From the beginning we knew we had a good arm design offered at a very reasonable price, but we honestly expected that it would take some time to get people to try something from a new company. What surprised us was the response from the industrial marketplace. Sales took off quickly in the first few months and within the first few years ETA distributors were receiving additional orders from major manufactures in North America and overseas. Through our very capable distribution network of technical sales engineers we soon had as customers the top aerospace, automakers, auto component suppliers, appliance, green energy, small engine, transportation, off-road equipment, and many other consumer product manufacturers.

We hope you will be as pleased with the value and performance of our tapping arms as the rest of our customers are.

Fit, function & longevity of the TA Series Tapping Arm comes from simple yet durable design and our tap arm systems come at a very practical price. Precision machining and hand fitting of components during assembly make ETA tap arms the Swiss watch of tapping arms. We back this statement with a 3 year warranty against wear-out. These floating tap arms offer the most flex ability in a tap arm. Movement of ETA tapping arms is virtually effortless. Threads are formed or cut without torque reaction because the tap arm keeps the tool from spinning. Once set up properly, the tap arm machine also guides the tap and keeps it in perfect alignment with the hole.
