Review: Adaptador cumple para lo que se requiere
Review: Incredibly handy - I find I often pull this out to trim something, often more than just a door. It is so much quicker and easier to use than a full size two handed planer. Great quality but as some have said, pressing the detent and switch is somewhat hard to activate and hold. Expensive, but so worth it

I find I often pull this out to trim something, often more than just a door. It is so much quicker and easier to use than a full size two handed planer. Great quality but as some have said, pressing the detent and switch is somewhat hard to activate and hold. Expensive, but so worth it

### ⭐ Failed to function properly
*by A***R on October 12, 2025*

I saw this and thought what a great idea! All of my tools are Bosch 18V so I have plenty of batteries and chargers. I bought a DREMEL 12v rotary tool just because of this adpater (Bosch & Dremel 12v batteries are interchangeable), thinking I won't have to purchase an abundance of 12v batteries. I did have to grind away the surface area in front so the battery would fully lock into place. This is to be expected at times. No problem there. The problem is that it doesn't work. I kept thinking that perhaps it wasn't fully seated. After numerous attempts, inspecting and measuring, I became frustrated and disassembled the entire assembly, plugged it in, and positively ensured it was making contact. I have 18 volts going in, 12 volts coming out but it will not power my tool. The polarity is correct, and I tried numerous batteries. Stumped.... Disappointed.... Useless. Now I have to buy an abundance of 12v batteries and a quick charger and lug all that extra madness around. Heads up, item will NOT fit the Bosch GLL3-330CG laser.
