10PCS Long Carbide Burr Set 1/8" Shank L 4" Die Grinder Bits for Dremel

It’s exactly what I expected

I used this to grind some pot-metal on the inside of a headlight housing. It did the job, and saved me about $300 on a replacement headlight. Just be careful when using this: they are long and can become uncontrollable at high speeds. Just be sure to wear eye/face protection and be sure this properly locked into the tool you're using it with.

Absolute garbage bits, they came in not even straight and wobble if you put any kind of slow to medium speed to them on a dremel, One bit even bent completely over while in the dremel

Bought the set for porting an aluminum intake manifold, and the bits all chew through aluminum efficiently. I can imagine they would be excellent for wood, resin, plastic, etc. Be careful when using not to bend the shafts- they're shipped in two seperate hard plastic cases for a reason! And if you are going to cut aluminum or other nonferrous metals, be aware of the speed and pressure you're using- consider using oil or another coolant to prevent galling and clogging of the teeth.

Good quality and length for the job I'm doing. But, they come packed in tubes of 2 and I noticed some of these arrived bent. I put them on my dremel, turned it on and they wobbled aggressively. No big deal as I will bend them back into shape.

Works great just what I need

These work OK, but there is the touchy period right at startup and stop(down?) in a dremel tool, where the rotational speed coincides with their physical length (what's known as a resonance in physics) is no bueno and they can bend. Yes, *bend*. After that they are trash. I would recommend paying more for a name brand. Or be prepared to by more later on.

Great bits , long for when I need it
