If not in proper alignment with the bore, a fluted chucking reamer will...

Explanation:
When the axis of a fluted chucking reamer isn’t aligned with the bore, the cutting edges engage the wall unevenly and pinch against the hole. This prevents smooth rotation and causes the tool to bind inside the bore. Proper alignment lets the flutes cut evenly along the centerline; misalignment disrupts that path and creates friction that locks the tool in place. Overheating or off-center holes can be byproducts in poor setup, but binding is the direct and immediate result of misalignment.
