Carbide Burr Set Die Grinder Bits Rotary Tool Bits 1/8" Shank 10 PC Double Cut Wood Carving Accessories Cutting Burrs Metal Grinding Engraving Polishing Porting Trimming

I have purchased several different Dremel accessory kits at places like Home Depot and Lowes, thinking I had a well-rounded set of items to handle most jobs. But when duty called, the parts failed. The bits on some of the grinders would literally fall off within 1 - 2 minutes of using them for their specified purpose. The final straw was when I tried to use the metal grinder accessory for 2 different kits I'd purchased ... and both fell off within 2 minutes on what should have been very easy applications.So I bought these directly after that situation and WOW - they work very well. The quality of materials is very distinguishable from the others, and I also noticed that the heads and the base are one piece - instead of something loosely attached to the base like the others. The metal grinder quickly allowed me to handle the job I needed it for. In fact, I then used the set to go back and finish 4 other jobs I had attempted but couldn't do because of my inferior prior accessories.When done they showed no sign of wear and I feel these will easily last me years and years. Glad someone out there still makes quality parts!

Arrived on time and in good condition, as described, appears to work fine so far, but i'm a hobbyist and not in production.

Nothing fancy but does the job. For what you pay they’re ok

Turning these cutters at 25k rpm’s provides a smooth and clean cut. I really like the different shape and size options. Highly recommend!

Got them to get the hard to reach spatter from welding. Does the trick

Works with my dremmel.

The tool bit itself is pretty good. Seems to last. The problem is the shank, it breaks very easily. Each of them that I used broke within a couple of minutes, even when I was very careful. Perhaps they can’t handle the heat that is generated? I don’t know.They are very affordable, but next time I’ll go for something a little more expensive in the hopes of finding better quality.

Ordered this set because I wanted to gasket match an intake manifold and grinding stones weren't doing it for me (wore out too fast, gummed up with aluminum). For that purpose, this tool has excelled. As recommended by the other reviewers here, I choke up as far as possible on the shank to avoid breaking it. I run the tool at about a 60% duty cycle to prevent both the burr and my Harbor Freight rotary tool from overheating. A few drops of cutting oil now and then, and I have yet to jam up the burr with aluminum. Personal preference, but I run the tool as slowly as possible; just fast enough to avoid chatter; it is very consistent and controllable.I think a lot of the negative reviews are coming from people pushing these little burrs beyond their intended use case. If you treat them as delicately as the precision jobs for which they were built, they should serve you well. If you want to pretend your Dremel is a pneumatic die grinder for hogging out bad welds... Good luck.
