Drilling and breaking a yorkstone sandstone block.
Watch this video of a large stone block from a yorkstone quarry being drilled and broken in half. The stone block is first drilled using a large pneumatic rock drill, then metal wedges called ‘plug and feathers’ are placed inside the drill holes. One ‘plug’ is placed in between two ‘feathers’ in each hole drilled. The plugs are then hammered down, forcing the stone block to break along the line of the drill holes. The blocks will then be turned into yorkstone paving or yorkstone walling products.
To see the yorkstone blocks being quarried, check out our other videos.

Ace. I’m breaking up a large sandstone rock in my backyard and I wish I could do it as quick as this.
