💡 What actually keeps router bits centered when running at full throttle? These holders rely on radial compression to squeeze the cutter evenly along its length. - Keep the seating area clear of debris so the tool sits flush in the main bore cavity - Hand tighten until firm resistance hits, since over twisting strips the outer threads fast - Stay within rated RPM limits to keep centrifugal forces from pushing the clamp outward
