Net force when deriving relation between torque and angular acceleration

When deriving the equation $tau = Ialpha$, it is assumed that $$F_{tangential}=ma_{tangential}$$$$a_{tangential}=alpha r$$$$tau=rF_{tangential}$$$$tau=mr^2alpha=Ialpha$$ However, doesn’t Newton’s second law describe that $Sigma F=ma$? And isn’t $Sigma F$ in this case equal...
