A Leader in Efficient Cutting Power
The new Zentool 21E2 is the result of a mountain of research and development. Using their experience and customer feedback from the first generation Zentool polishers, the design team at Zen Automotive Supply in Australia, set their sites high. The goal was simple to say but difficult to accomplish: to create the smoothest, quietest, user-friendly long stroke dual action polisher on the market today.
Starting from the cord, everything was changed. The cord is now an ultra flexible and soft SJO cord, 10 feet long. To make it last longer and foster good storage habits, the Zentool comes with an attached Velcro cord keeper.
The tool body was a big part of the new design. User ergonomics were the main consideration, solidity, and quality of materials came next with the aesthetics of the tool also weighing in. The handles are comfortable and textured to allow for better control without the need for a strong grip on the tool. The front handle was given a lot of attention and testing. Itâs a composite structure that is quite thick. Joel is a detailer and knows that tools get dropped; so while itâs not unbreakable, itâs very durable.
One other feature of the casing is the externally accessible brushes. Brushes are the part of any tool that requires the most maintenance. Making them accessible without having to disassemble the casing is another great attention to detail.
Inside the casing is a where the real magic happens. Connected to that supple power-cord is a simplified switch and speed controller. The designers managed to make the wiring simpler, and even more reliable. The less connections you have the better it is. Those controls are connected to a more powerful 600w high torque motor. This little jewel of engineering runs cooler, creates more power, and does so with a generator friendly 300w less power consumption. The armature is dynamically balanced on a state-of-the-art machine that reduces vibration from the motor. The fan design was changed to increase airflow and cooling while reducing sound.
The precision machined gears are cut in such a way that they are always in contact, further reducing noise and vibration. The gear casing is filled with a high-quality lithium based grease for long life and cooler running.
The business end of the Zentool 21E2 where it converts all that rotation to a 21 mm dual action is a thing of beauty. Precision machining meets computerized modeling to make an offset counterweight assembly that is a jewel. The design team managed to increase the rotating mass. This means smoother running and not as pad-weight dependent to maintain that smooth vibration-free experience detailers need. Having a higher rotating mass allows the Zentool to work comfortably with both the included 5" and 6" cross ventilated backing plates.
