8250 12V Lithium-Ion Variable Speed Cordless Rotary Tool with Brushless Motor, 5 Rotary Tool Accessories, 3Ah Battery, Charger, and Tool Bag

Users outside the US and Japan need to purchase a separate 220V charger; otherwise, the battery will not charge.

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.

部品取り付ける用の軸が添付されていなかったので、付けられないですです。 パワーは、Dremel 4000よりあるみたいです。 予備バッテリーを探しているのですが、どこにも無くて困ってます。

El producto cumplió con lo que necesitaba es de excelente calidad

Works great. I had no idea how much I was going to love not having a power cord. I will never get a corded Dremel again. The charge lasts a long time and has lots of torque.

Product material looks poor and the indicator lights are like cheap products. Better to check for other alternatives before deciding to buy this
