Is a spinning frame of reference an inertial frame of reference?

2. Relevant equations

net torque, net force = ma, equilibrium --> net force = 0, net torque = 0

I've learned that an inertial frame of reference is a frame of reference which is not accelerating.

3. The attempt at a solution

I would guess that it is, based on the concepts of netwon's first and second law, and equilibrium. If an object is in equilibrium, this means there are no net forces or net torques acting on it. Assuming the spinning "frame of reference" is in equilibrium, then there are no net forces acting on it. No net forces acting on it means that it is not accelerating (f = ma). Since it is not accelerating, it is an "inertial frame of reference". So I believe a frame of reference that is spinning would be an "inertial frame of reference" (assuming the force that caused the torque intially is no longer active). But, I am not confident of my conclusion.
