Point Cold Chisel (4x18x300)

The extra length is about your hands. On a hand-struck chisel, the length is what puts distance between the hammer and your fingers, and it is also what lets you reach into a hole you are breaking out, a chase you are deepening, or a joint set back from the face of the work. Every hundred millimetres of chisel is another hundred millimetres your hand can be from the blow and from the flying debris. On demolition and breaking work, where blows are heavy and the material sprays, that is worth having.

The thicker 18mm body is about stiffness. A chisel is a column being loaded on its end, and a longer one is more prone to flexing and to being deflected by hard material. Increasing the body diameter as the length increases keeps it rigid, so the energy travels straight down to the point instead of being lost in flex.

The point concentrates the whole blow into a tiny area, generating the very high local pressure that splits and fractures material rather than cutting it. That makes it the tool for breaking brick, block and stone, starting a break in concrete, punching through masonry, breaking out mortar and tile beds, and cracking seized assemblies apart.

The protect grip is a safety component, not a comfort one. It is a flared sleeve between the struck end and your fingers, and it takes the missed hammer blow that would otherwise land on your knuckles — which, with one hand holding and one hand swinging, happens to everybody eventually.

The hazard that deserves the most attention is mushrooming. The struck end of a cold chisel is deliberately softer than the cutting end so it absorbs blows, and it gradually spreads into a mushroom with thin curled edges. Those edges are brittle and eventually break off under a hammer blow and fly at speed — a well-documented cause of eye injuries and embedded splinters. Grind the head back to a clean chamfer at the first sign of curling, and keep it slightly bevelled. A mushroomed chisel is not a worn tool to be tolerated; it is a hazard to be dealt with before the next blow.

The material is carbon steel, heat treated, with a powder coated finish that resists rust in a damp toolbox.

The buyers are masons and bricklayers, demolition and building contractors, plumbers and electricians breaking out for services, groundworkers, and hardware dealers supplying construction.

Eye protection every time. Strike square. Keep the point dressed sharp, since a blunt one skids and doubles the number of blows. Message us on WhatsApp for a price, or for the shorter 250mm version for confined work.
