Yes. Looks like 45 but was so fine on repasses can't really see last stroke of hone stones. As explained by machinist.. a sunnen fully digital automatic bore/hone bar head and cnc control of stroke of axis. Supposed to be better than oem, better ring break in + longevity. Awaiting bore gauges to measure and double check. Was nice to have bore edge chamfered correctly too. No fist shaving as I checked bore cleanliness.
