The heavy rock splitting wedge is a tool for splitting large and hard stones, rocks, granite, marble, and concrete. It uses non-blasting methods and can replace traditional methods for secondary blasting and chemical separation, making it environmentally friendly. Made from high-quality spring steel, it is durable and features a frosted, non-slip surface for faster splitting. To use, pre-drill a borehole 2mm larger than the wedge’s diameter (1.02 inches/26mm) with a depth of 7.5 inches/190mm. Note: Not to be used on steep slopes and always take necessary protective measures when working.
