  • Cutting molded grating: Depending on the amount (linear feet) of grating to be cut, a variety of shop tools can be used. For best results, use a heavy-duty rotary saw with a masonry, carbide, or diamond coated blade. Firm support of the panels will prevent shifting. Turning the panel bottom-side-up gives a smooth surface for the saw to ride on and reduces chipping. Be sure to allow for the blade kerf (3/16″) when measuring.

    In addition to breaking through rocks, tunnel bench drilling bits also play a role in stabilizing tunnel walls. As tunnels are excavated, the surrounding soil can become loose and unstable, posing a danger to workers and the structural integrity of the tunnel. Tunnel bench drilling bits are used to create holes for support structures such as bolts and mesh, which help to secure the tunnel walls and prevent collapses. By stabilizing the tunnel walls, these drilling bits ensure the safety of workers and the success of the tunneling project.

    Crafted from tungsten carbide, a compound known for its extreme hardness and wear resistance, these drill bits boast an unrivaled durability that allows them to outlast high-speed steel (HSS) bits by a considerable margin. Their design incorporates sharp cutting edges and a unique geometry that reduces walking, ensuring holes are drilled with precision and accuracy. This level of performance is particularly critical in applications where exact hole placement and clean hole finishes are paramount.
