Detonating cord for quarries and stone cutting
Detonating cord has found its way from the quarries into the stone cutting work sites.
Nitrocord 25/40 g detonating cord is rapidly replacing pipe charges by being both cheaper and easier to use. Cutting power of the detonating cord is exceptionally good, and it leaves a smooth and clean edge to the rock.
We also supply sizes between 10-100 g, and there is also a smokeless version available.
