Titanium Carbide Rotary Burr Set - 10pcs Double Cut Tungsten Steel Die Grinder Bits, 3mm(1/8") shank and 6mm(1/4") Head Size for Woodworking, Drilling, Metal Craving, Engraving, Polishing

I had to cut open a frozen trunk latch on our minivan. I went through a couple boxes of the diamond coated bits and several hours of work without success. I also shopped all the local tool stores and a couple big hardware stores and nobody sold bits like this.These bits worked great! One bit, that is still usable, and a half hour and I had the trunk open. If you have to grind metal with a dremel then buy these.

I gave this to a creative woodworker as a gift, and they were delighted ... and were very eager to use them the very same day. I'm going to take that as a ringing endorsement of the worthiness of these bits ...

Je n'ai pas encore essayé sur mes créations de bois mais ca l'air solide, intéressant. Livraison rapide.

These burrs are worth the $. I'm still a novice, so I still like to experiment with different burrs, and how they will suit my needs. These have become my go to do anything on virtually any surface! Definitely recommended!

It works good, ends are brittle but stand up really well 👍
