Dremel always amazing

Great tool to use. A bit bulky but 12v supply with 35000rpm still available its worth it. However keep in mind that Amazon US supplies at 110V so make sure when ordering. I am still looking for a replacement charger to get the battery charged it is so upsetting......

Picked during Prime Deals and have no regret.

IMPORTANT! If your tool is flashing green when it is turned on, set it 10 to 15k and try again. Toggle on and if it still flashes try again. Now to the review. This is a great tool. It's got plenty of power and can SAND through a board. Not just cut. With a SANDING DRUM you can go through a board. It doesn't bog easily above 10krpm. It is great for cutting bolts, cutting sheet metal, sanding metal and wood, rough and fine shaping in wood. Fine shaping in aluminum, polishing steel, rough axe or lawn blade sharpening, engraving, and much more I haven't done yet. The battery life is good, but it leaves some to be desired. It can be gripped like a golf club for grinding, and shaping, or like a pencil for fine and detailed work. The battery charges in 30 to 40 minutes. It is quite heavy, but not enough to stop most detailed work. I can't say much about durability, as I've only had it for a week, but I've got it covered on sawdust, metal dust and splashed with water lightly. This is a brushed tool, but there is not a way to change brushes, so I guess you replace it. Fine with me for 70$, but might be a deal breaker for some to replace every 150 hours. It is a great starter dremel though. You will have to buy a lot more accessories to fuel your rotary addiction, but at this price it's pretty easy to. The carrying case is a huge bonus. It fits my 110 piece accessory kit with the charger, tool and battery. I overall, a great buy.
