Reverse circulation drilling machine horizontal hole drilling is a high capacity, versatile drilling machine which can be used to drill large diameter holes by the raised drill or blind shaft methods. It used for vertical or horizontal drilling operations on hard geological formations such as granite, quartzite as well as any other high strength materials.
Raise boring tbm (tunnel boring machine parts) Cutter are usually applied to bore very hard and very abrasive rock. We manufacture 8",12",15"raise boring cutters with different carbide rows. The cutters with carbide buttons, namely button disc cutters, TCI disc cutters, are easily mounted in raise boring head with the saddles in certain patterns to get different spacing between the rows to suit different geological conditions. Generally, large row spacing is fit for soft rock and narrow row spacing is fit for harder formations.
· Cutter cones are forged with high quality alloy steel, and heat-treated to proper balance between hardness and toughness.
· Carbide inserts can be selected from a wide range of shapes, sizes and carbide grades to ensure long service life and high penetration rate.
· Carbides are inserted in cones with different rows. The combination of cutters with different rows Carbides results in different spacing to suit different rock formations.
· Cutters can be easily mounted on the saddles and positioned in raise boring headin certain patterns with different spacing to suit different rock formations.
