GROUP B CARBIDE BURR #9

The double cut design chews through mahogany and plastic without bogging down, which is exactly what I needed for my carving work. Shaping softer metals like aluminum is a breeze too, and it's held its edge through a full afternoon of use.

I was skeptical about using a carbide burr on plastic, but the double cut design left a surprisingly smooth finish on acrylic sheets without melting or chattering.

I've been using it to clean up edges on plastic parts and it doesn't grab or chatter like my old bits did. The double cut design leaves a surprisingly smooth finish, so I barely had to sand afterward.
