GROUP B CARBIDE BURR #7

This carbide burr chews through some pretty hard maple for shaping without bogging down. The double-cut teeth leave a fairly smooth finish that needs less sanding than I expected.

The double cut design eats through plastic and soft aluminum without clogging, which is exactly what I needed for a quick shaping job. Shaft fit was solid in my rotary tool, and it kept its edge through a full afternoon of use.

I was surprised how smoothly this burr cuts through aluminum—no grabbing or chattering like cheaper bits. The double cut design leaves a nice finish, and it's held up well in my drill press.
