If you’ve been in the hobby world for a while, you probably know DSPIAE. It’s one of those brands that has earned the trust of modelers thanks to tools that are clever, practical, and above all, precise.
The ES-A Reciprocating Electric Sander quickly became a favorite when it was released. Small, easy to handle, and very efficient, it was the perfect ally for anyone who wanted to move past manual sanding and get faster, cleaner results. Many builders have been using it on Gunpla, scale models, and miniatures with great success.
But DSPIAE didn’t stop there. Listening to feedback from hobbyists worldwide, they went back to the drawing board.
Now DSPIAE has decided to take things a step further. Listening to the community, they’ve introduced the new DSPIAE ES-A PRO. This isn’t about replacing the original, but about offering a more advanced option for those who want extra power, control, and durability. With an optimized motor, a full metal body, and thoughtful additions like the LED status bar and expanded accessory kit, the PRO sets a new benchmark in its category.
In this article, we’ll walk through the key differences between the ES-A and the ES-A PRO so you can decide which one is the better fit for your bench.
🔧 Design & Build Quality
DSPIAE ES-A (Original): Compact and lightweight, designed for easy handling. Its mixed-material construction makes it accessible and comfortable, especially for hobbyists who are new to powered sanding.
DSPIAE ES-A PRO: Upgraded with a full extruded alloy body. This gives the tool a premium feel, greater durability, and a balanced ergonomic design for longer sessions without fatigue.
⚙️ Motor & Performance
ES-A (Original): Equipped with a standard motor delivering reciprocating action at speeds up to 3600 RPM. A reliable choice for speeding up repetitive sanding tasks on plastic parts.
ES-A PRO: Re-engineered with an optimized motor and drive system that offers smoother reciprocation and steadier torque. With adjustable speeds reaching up to 5400 RPM, it maintains consistent performance even on resistant surfaces, reducing vibration and ensuring finer results.
🎯 Precision & Control
ES-A (Original): Provides clear time savings compared to manual sanding and is ideal for everyday modeling tasks.
ES-A PRO: Adds enhanced vibration damping and ultra-fine reciprocation, making it especially effective for curved, angled, or highly detailed parts. The result is a more controlled, precise finish that elevates complex projects.
🔋Power & Charging
ES-A (Original): Powered by a rechargeable battery with up to 1 hour of runtime. USB-C charging keeps it simple and convenient.
ES-A PRO: Includes a direct connection charging module for a stable and efficient charge. A new multi-color LED status bar provides real-time feedback on battery level and operation, so you always know when it’s ready.
Both versions come with DSPIAE’s precision sanding heads and essential accessories.
