Reaming involves re-cutting an existing taphole with a slightly larger diameter bit to remove dry wood and microbial growth that can restrict sap flow. By widening the hole just enough, you clear out buildup and keep the flow steady as the season progresses. This maintenance helps prevent blockages and keeps tapping sites productive. Pruning is about trimming branches and has no relation to tapping holes. Pubescence refers to a hairlike coating on plant surfaces, not to tapping practices. A preheater is equipment used to warm sap or lines, not to clean or widen tapholes.
