Dremel has been the leader in the rotary tool market for some time, and the introduction of the new 8220 Lithium-ion Cordless Rotary Tool kit means that they now have an even wider appeal. While their existing lineup, including the popular Dremel 4000-2/30 High-Performance Kit, is very capable, the 8220 allows portability not found in previous incarnations from the company. Partially, this is because their other cordless tools, particularly the 7.2V MultiPro and 4.8V MiniMite, all fell short when it came to power and longevity. Even the 10.8V, while technically very similar to the 8220 in power and capacity, carried the same 3-hour charge time for its Lithium-ion batteries. Now, Dremel has borrowed from parent company Bosch, integrating their 12V Max technology, and bringing its latest cordless rotary tool’s recharge time down to a manageable one hour.
