Carbide Cutting Tools
A 5 pack for $22.95

We discovered some really great motor tool cutters that will really speed up your model building chores. These carbide cutters feature a drill point end with a fine tooth, high helix design cutting edge that really eats through plywood, fiberglass or carbon fiber.
Each pack contains (2) 1/16", (2) 3/32", and (1) 1/8" diameter cutters all with a 1/8" shank to fit your motor tool. Once you try them, you'll never want to be without them and you can't beat the price!
As always wear safety glasses when working with rotary cutters of any kind.
