Dremel Cordless Rotary Tool: Brushless Performance with a Lifetime Warranty
Dremel is renowned for its rotary tools, much like Kleenex is for paper towels. The brand has been active in the cordless tool market for over a decade. Over the years, our writing instruments and rotary tools have seen significant improvements. The Dremel 8250 is a prime example of the latest technology in action.
Performance of the Dremel Cordless Rotary Tool
One of the standout features of the Dremel 8250 is its brushless motor, powered by a 3.0Ah 12V battery. Compared to the corded Dremel 4300, which is Dremel’s most powerful corded model, the 8250 provides 20% more power. Additionally, it outlasts the cordless 8220 when it comes to run time, allowing for extended cutting of 1/4″ lag bolts.
But what does all this mean? Brushless motors are more efficient than brushed motors, offering improved power and longer run times without the need to replace carbon brushes. If you’ve used an earlier model of the Dremel cordless rotary tool, you may have noticed that you can apply more pressure while cutting and sanding without the tool stopping. However, tasks may take longer to complete.
Adjustability and Safety Features
The Dremel 8250 allows you to adjust the motor speed using the dial below the on/off switch. You can select a speed range from 5,000 to 30,000 RPM. The dial has detents that smoothly slide into place, ensuring seamless transitions between speeds.
To keep you informed, there is a blue LED light that illuminates in 5,000 RPM increments. This provides clear feedback on the current speed setting. Additionally, a red indicator light warns you of overloads and high temperatures, ensuring safe and efficient operations.
Design and Ergonomics
Measuring 9.6 inches in length, the Dremel 8250 is designed for high performance. It offers a slightly thicker waist and widens towards the rear to accommodate the 12V battery. Despite its power, it weighs only 1.3 pounds, making it comfortable to handle and operate.
The tool features ample rubber overmolding, enhancing both comfort and grip security. Furthermore, it comes with a built-in wire tool hanger, providing convenient storage during breaks.
Pricing and Warranty
The Dremel 8250 is available in several configurations. The basic kit includes the tool, a 3.0Ah battery, charger, and a 5-piece accessory kit, priced at $149.99. Alternatives include a kit with a flex shaft attachment for $184.99, as well as a comprehensive 160-piece accessory kit for $224.99.
Here’s the exciting part: Dremel stands behind this tool with a limited lifetime warranty. Compared to the previous model’s 2-year warranty, this is a significant improvement. The batteries also come with a 2-year warranty.
The Bottom Line
The Dremel 8250 Cordless Rotary Tool boasts superior power when compared to corded options and offers extended run times, making it a worthwhile corded alternative. While it excels right out of the box, heavy-duty rotary tool users may want to consider adding a second battery for uninterrupted operations. Precision users, on the other hand, can benefit from the addition of a Flex Shaft.
