## Description

Brushless power to perform, runtime to last. From cutting to sanding, and grinding to drilling the Dremel 8250 delivers corded performance without the inconvenience of a cord. Featuring an advanced brushless motor, the 8250 provides optimized motor efficiency, more runtime & power, and long tool life. With 20% higher power vs Dremel’s most powerful corded tool the 4300, the 8250 provides maximum versatility to perform the widest range of applications and is compatible with all rotary tool accessories & attachments. The powerful 12 Volt / 3 AMP Lithium-Ion battery provides superior performance & runtime at all speeds; delivering 100% more runtime vs the 4300 ensuring that the 8250 will still be going strong when you need it. The innovative tool design is engineered to exceed endurance tests for consistent & powerful performance every time, while the ergonomic body provides a comfortable grip zone making it ideal for extended use. The 8250 gives you the confidence & performance to tackle the toughest of jobs.

Review: Charging error... only 120V No: 120V~220V - Users outside the US and Japan need to purchase a separate 220V charger; otherwise, the battery will not charge.
Review: Defective battery & tool shuts off on high spee - Unfortunately, the product has multiple serious issues that make it unusable. First: While charging, the indicator shows green as if the battery is full, but once installed it turns blue and remains extremely low. The tool shuts off after only a few minutes. I charged it multiple times for long hours with zero improvement — a clear sign the battery is defective or old stock. Second: Even when trying to use the tool, it immediately shuts off when set to a high speed level. It cannot handle even minimal load, which indicates either an internal fault or a battery that cannot provide enough power. This is not a minor defect — the product is simply not usable. The customer loses, while the seller benefits from selling a faulty product at a high price. This is unacceptable, especially from a brand like Dremel. I strongly advise checking the battery and tool condition before buying, because the issue is obvious from the very beginning.

Very nice kit and Dremem tool. Has one battery and couple of collets. A little pricey but is brushless and works really well not having to worry about a cord when doing a job.
