Sharp and durable.
This is a great burr, sharp, durable and very tough. I real use my tools, I have a professional metal business, so literally this is used extensively on a daily basis. Even when it has been abused, bot on purpose I might add, but an accidental hangup or rough cut that would bend the shank of other burrs on the market these ones still run true and do not deform. Basically if you want a good carbide burr that will last most homeowners or hobbyist a lifetime then this is it. I have some of these that have 100's of hours worth of use on them and they are still milling A500 steel like butter. Little word of advice from a professional, if you are going to use these extensively invest in some good cutting oil, it will give you a better finish, increase the material removal, increase the life of the tool and keep the burr sharp and limit clogs, especially in materials like aluminum or lead. Follow that easy rule and they will cut like no other! I am not a paid spokesperson or affiliated with the company at all. I build professional Aluminum Trailers and Military Items SIC Metals in Clarion PA. We use these burrs to clean out A500 in house shakle links and corner welds.

Good quality
Use this for grinding metal on sculptures. Work better at lower speeds. They tend to take off when used in my air grinder. Work great in the battery op ones or plug in type.

Worked great for my purpose
My use is fairly unique. Used to de-burr the half-round holes bored into PVC trim board for accents (similar to spots on dominoes) . Rotary burr tears through the pvc leaving a nice smooth hole.

Good Quality but What About Size?
Dul Series SB-41. I ordered a 1/16 burr bit and it is advertised as such but how can this be? Here it is side by side next to a 1/16 drill bit. It obviously is wider in diameter. Is there something I don't know about burr bits and their sizing? Any replies are welcome.

Doesn't last long.
Used to clean 5/8 holes and only stays sharp for about 10 holes. I had 1,680 holes. Will not buy again.
