Forgive me if I seem a little preachy, but quite a bit of people misunderstand what this tool is for: this is a high speed, LOW torque (in other words, do NOT apply excessive pressure), LOW amp (not much mechanical power), multi functioning rotary tool. Dremel will most likely NEVER make a rotary tool that is high speed high torque, high amp, because that's not their niche. This is for weekend warriors, do it yourself-er types, this for crafts and hobbies, this is NOT an indus..
