Hyper Tough AQ25000S-A 1.5-Amp, 106-Piece Rotary Tool and Kit

I had a "D" name brand tool for quite a few years. It got infrequently, light use for most of the time and when I put it to some heavier use, the motor went up in smoke. I replaced it with this unit, and have had it for over 2 years. It is more powerful than its name brand predecessor, and it likely has seen more and heavier use in 2 years than my old one did in 10. Performs flawlessly.

People have had two issues with this tool. which I solved. --Collet not holding tool bits. There was a burr in my collet that stopped the bits from going in more than 1/4 inch---File the burr out, or just tap the bit in and it will break the burr. When fully inserted and wrench tightened the collet is as good as any. --Not enough torque (power). Yes, it is a moderately powered tool, with tiny bits. 1/8th inch shank cutters should let you know none of these small tools are for large metal removal projects, but it does what it was designed for well. The minimum 8,000 rpm is way too fast for large cutters, buy a 1/4 inch shank rotary grinder or a 4&1/2 inch disc grinder for big work. You can buy all three for less than the cost of one dremel tool.
