I’ve just taken delivery of a core-splitter made by Helmut Kawohl in Germany. He personally delivered the rig and it is absolutely excellent! I’ve seen cores split all sorts of different ways over the years – hand and electric saws, Dremels, tile cutters – none of which were ever particularly satisfactory (or safe!). This new rig makes perfect cuts in plastic tubing (haven’t tried metal yet) – for large bore core it can also usefully put double cuts in so a slab can be extracted from the centre.
Helmut has drilled fixed positions for the adjustable surfaces to accommodate our most used core tubes, but the cutter is fully adjustable for any diameter and wall thickness, and can split cores up to 1.5m long.
Core cutting will no longer be a messy, unpredictable team operation!
