Given vectors $\overrightarrow{a}=(-3,1)$, $\overrightarrow{b}=(1,-2)$, $\overrightarrow{m}= \overrightarrow{a}+k \overrightarrow{b}(k\in\mathbb{R})$.  
$(1)$ If $\overrightarrow{m}$ is perpendicular to the vector $2 \overrightarrow{a}- \overrightarrow{b}$, find the value of the real number $k$;  
$(2)$ If vector $\overrightarrow{c}=(1,-1)$, and $\overrightarrow{m}$ is parallel to the vector $k \overrightarrow{b}+ \overrightarrow{c}$, find the value of the real number $k$.
