The 56mm Core Drill is the standard size for most stainless steel balustrade post coredrill installations — the diameter most commonly required when setting round and square posts into concrete, stone, or masonry substrates using anchor fix epoxy. If you are installing coredrill posts and are unsure which drill size to specify, the 56mm is the most likely correct choice for a standard residential balustrade project.
Its 56mm cutting diameter produces a clean, precise hole that accommodates the post stem with sufficient clearance for the epoxy to flow evenly around it and cure with full bond strength on all sides — the critical requirement for a structurally sound, permanently set coredrill post.
Heavy-duty barrel construction delivers smooth, accurate cutting in concrete, stone, and masonry with professional-grade precision and durability. Sold individually.
