  • Low speed!
**Low speed use only. They will bend at high RPM. Very sharp and work well for hard to reach places. Take your time and keep RPM low. If I only use them once or twice a year they are worth the price.

  • Great value, cuts...okay
These would probably be better suited for cutting aluminum. I had them in a Dremel tool and was trying to work my way out to the outside of a head bolt that was busted in an engine block. They were terribly slow to cut, but I imagine they would work considerably better on aluminum or maybe even plastic? They are accurate in length and vibrate a fair amount if you don't stabilize them or if you have the speed too high. However, for as many as you get, this is a nice deal worth trying. ... show more

  • Warning at high speed they warp and bebd
The burrs are great but the long shafts warp and bend at high speed and cause injury to hands and possibly the face

  • Great for fine hobby work.
Well packaged. Sharp bits. They do exactly as I wanted. I'm mostly cleaning out plastic airframes for RC aircraft. Good value for the money and fit well in a standard Dremel.

  • Horrible and unusable.
Didn't receive a single bit with a straight shank. Every one of them oscillate, when in first use before making any contact, in the rotary tool for having bent shanks. And so they cannot be used...at all. Horrible quality...is the best I can say about this product.

  • Better than expected
I bought these to hog out 16ga 304l stainless steel tubing. Shockingly, they worked great! Moved some serious metal. I did have to be cautious with the speed and feed of course.
