Marcrist PC850 3 Piece Diamond Core Set

The Marcrist PC850 3 Piece Diamond Core Set is a comprehensive dry diamond coring kit designed for plumbing, heating, and electrical specialists working with hard building materials.

The set covers three of the most commonly required core sizes — 38mm, 52mm, and 117mm — making it a versatile choice for running pipework, conduit, and cable through walls and floors. All three bits feature an 8mm segment height and 165mm core length, suited to dry drilling through non-reinforced concrete, brick, London bricks, natural stone, calcareous sandstone, Poroton, and concrete pipes.

Every essential accessory is included straight out of the box: a 200mm pilot drill, drift key, 1/2" jaw chuck adaptor, and extension rod. The kit is supplied in a sturdy aluminium carry case, keeping components organised and protected between jobs — a practical benefit for contractors moving between sites.
