DremelMax Life 115HP 5/16" (7.9mm) High Performance Rotary Carving Bit, 2-Pack

I bought these to rout out hinge recesses in wood doors, for thicker spring load hinges that I installed. They work very well, and are very sharp. Took only a minute per hinge recess to deepen each one. Much better and cleaner than using a chisel to deepen the recesses.I have also used them to enlarge door lock cut-outs in door frames when I adjusted the strike plates to get doors to fit tighter against the seals.Highly recommended!

Bought the 2-pack assuming I would burn out one before completing my address sign before finishing. Carved out 5 numbers with a single bit in cedar at 3/16" depth and the bit is still sharp. Started at 30K rpm on the Dremel but found it burning a bit so finished the project between 15-20K rpm.Will buy these again if needed.

I got this to remove old glazing from windows. It worked but I tried steaming and steaming worked better to remove old hardened glazing.

Works as expected of Dremel. I've purchased less expensive "equivalents" and found them lacking. These bits hold up well when used as directed and not allowed to overheat.

Keep it cool and the head lasts forever.

so these 2 are someone else..power to a whole different level

dremel bits are hard to beat

Purchased for an aluminum milling job honestly probably too big a job for a dremel, but they worked well. Pay attention to speed guidance, these will gum up with aluminum if you run the RPM too high. (12 to- max15K RPM works well) maybe overpriced, but a nich product and they will probably be around long enough for me to get value out of them
